First, let’s understand what is software testing:

What is software testing?

Software testing is the procedure of analyzing a software program or system to find and fix bugs or faults. It guarantees that the program complies with the requirements set out, performs as intended, and is free of any flaws that can impair its functionality or usefulness. As such, it is a crucial part of the software development lifecycle.

Software testing may be carried out manually or automatically, and it entails a number of steps including test scenario identification, test case creation, test execution, and test result analysis. Unit testing, integration testing, system testing, and acceptance testing can all be done at various phases of the software development process.

Software testing’s primary goals include finding flaws or faults in the program, making sure it complies with all criteria, enhancing the program’s quality, and boosting user trust in it.

Effective software testing may assist to enhance the software’s overall performance and dependability, increasing user happiness and the project’s likelihood of success.

Benefits of software testing

The life cycle of software development must include software testing as a critical component. It entails the process of inspecting a software program or system to find any flaws that can affect the user experience. The following are a few advantages of software testing:

  1. Detecting defects: Software testing helps in detecting defects early on in the software development life cycle. By detecting defects early, developers can address them quickly and avoid the cost of fixing them later.
  2. Improving software quality: By testing software, developers can ensure that the software meets the quality standards set by the company or the industry. This, in turn, improves the overall user experience.
  3. Ensuring reliability: Testing helps in ensuring that the software is reliable and performs as expected. This is important for critical applications such as those used in healthcare or aviation.
  4. Enhancing security: Testing helps in identifying security vulnerabilities in the software, which can be fixed before the software is released. This is crucial for applications that deal with sensitive information.
  5. Reducing maintenance costs: By testing software, developers can identify defects early on, reducing the cost of maintenance in the long run.
  6. Meeting regulatory requirements: Many industries have strict regulatory requirements that software applications must meet. By testing software, developers can ensure that the software meets these requirements.

What are the 7 principles of software testing?

Bellow are listed the 7 principles of software testing

Testing shows the presence of defects

Finding and recording software system flaws is the main goal of software testing. Testing’s goal is to show that bugs exist rather than to prove that the program is defect-free.

Software testers may aid product developers in understanding and resolving issues with the software by identifying flaws. Software testing is therefore a crucial part of software quality assurance.

Exhaustive testing is impossible

It is difficult to test every input-condition combination that a software system could experience. Numerous situations and input combinations are available with even the most basic software systems.

As a result, software testers must focus on the most important and likely situations while utilizing a risk-based approach to testing. The most likely flaws and risky regions must be identified by testers using their knowledge and skills.

Early testing saves time and money

The later in the software development life cycle a fault is detected, the more expensive it is to rectify it. Defects are easier to rectify and less expensive to remedy the sooner they are discovered.

Software testers should thus participate in the software development process as early as feasible, collaborating closely with developers to guarantee that errors are found and fixed as soon as possible.

Testing should be independent

To be impartial and objective in their testing, software testers should be separate from the program development team. Without worrying about prejudice or retaliation, testers may find errors and give feedback to the development team when they are independent.

Additionally, independence contributes to ensuring that the software is of the best caliber and that the software development process is transparent.

Defect clustering

Software development is characterized by a phenomenon called defect clustering, in which errors frequently gather in particular regions of the software. Defects, for instance, may group together in a certain module, function, or business process.

Because some parts of the program are more complicated and need more work to build and test, defects tend to cluster in those regions. Software testers must thus pay close attention to various components of the software system to guarantee that flaws are found and fixed.

Pesticide paradox

The pesticide paradox is a phenomenon in software testing when the same tests are run repeatedly over time but no longer find the faults that were previously found.

The pesticide paradox happens because software testers frequently concentrate on the same tests and scenarios, which makes it harder for them to spot new flaws.

Software testers should continually examine and update their testing methodologies, concentrating on new components of the software system to find faults that had not yet been found, in order to avoid the pesticide paradox.

Testing is context-dependent

Software testing is context-sensitive, therefore the testing methodology and technique must be adjusted to the unique needs and traits of the software system under test.

To guarantee that the testing is thorough and efficient, the testing methodology must take into account the technology, platform, business requirements, and user demands of the software system.

To guarantee that testing is incorporated into the software development process, testing must also be modified to the particular development methodology being used, such as agile or waterfall.

Software testing is a crucial step in the creation of high-quality software, to sum up. Software testers may find errors and give feedback to software developers by adhering to the seven principles of software testing, assisting in ensuring the greatest level of quality for the software system. To achieve software quality, software testers must use a risk-based testing strategy, concentrate on defect clustering, and avoid the pesticide paradox.

Functional testing

In this article, we will explore the subject of Functional Testing, what it is, and why it is important to perform it in any software project. We will cover some subjects, like what methods of functional testing are there, what are the benefits of it and we will share some examples of functional testing.

But first, let’s understand what functional testing means:

What is Functional Testing?

A form of software testing known as FUNCTIONAL TESTING verifies a software system against functional specifications and requirements. Each function of the software program is tested using functional tests, which involve supplying the right input and comparing the output to the functional requirements.

Functional testing mostly includes “black box” testing and is unconcerned with the application’s source code. This testing examines the Application Under Test’s User Interface, APIs, Database, Security, Client/Server connection, and other functionalities. Testing can be carried out manually or automatically.

What are the 3 types of Functional Testing?

3 major types of functional testing are as follows:

  • Unit Testing
  • Integration Testing
  • Smoke Testing

What types of Functional Testing are there?

You can see a list of the many functional testing categories below.

Unit Testing

Performed early in the development process, assisting in discovering flaws at this point. This helps avoid incurring greater repair costs for problems later in the STLC.

Methods employed include:

  • Branch Coverage: Testing covers each of the logical connections and outcomes (True or False). For instance, all branches of the path are If and Then conditions in a code If-Then-Else sentence.
  • Statement Coverage: When testing, each statement in the function or module must be visited at least once.
  • Boundary Value Analysis: The test case is then performed utilizing all the prepared datasets. The test data is created for the boundary values as well as for the values that fall just before and just after the boundary value. Days of Month, for instance, may accept values from 1 to 31. As a result, the test case will also be examined for the invalid conditions of 0 and 32 in addition to the legal boundary values of 1 and 31.
  • Decision Coverage: All selection routes are checked during the execution of Control Structures such as “Do-While” or “Case statement.”

Integration Testing

The software consists of two or more unit-tested components that are combined and tested to ensure that their intended interactions occur.

Seen between units, the transmission of instructions, data, DB calls, API calls, and Micro-services processing occurs. No unexpected behavior has been noticed throughout this integration.

Interface Testing

The accuracy of data interchange, data transmission, messages, calls, and instructions between two major parts is evaluated as part of integration testing. Through interface testing, the application’s communication with a database, web services, APIs, or any other external component is evaluated.

System Testing

The system as a whole is tested for compliance and accuracy against the specified requirements after combining all of its components. The integrated system is verified using a Black-Box testing approach.

System testing is carried out in a setting that is close to real life and by real-life usage.

Regression Testing

When a design deviates from an established workflow due to a technology or complete redesign, UX regression, or a step back in the quality or usability of an application’s or website’s user experience, can happen.

Smoke Testing

Smoke Testing is done on the application after development, when a new build is published, to make sure that all end-to-end major functionality functions. It is typically performed on early, unstable versions of an application that were produced during development.

Any important functionality that is found to be broken during testing results in the rejection of that build. The issues must be fixed, and a fresh build must be made for additional testing.

Sanity Testing

Sanity tests are chosen from the suite of Regression Tests to cover the main features of the application. For a somewhat stable application, developers do sanity testing on the fresh release.

An application is prepared for the following level of testing after it properly passes the Sanity Testing.

Acceptance Testing

The end-acceptability users of the application are tested during acceptance testing. The purpose of this testing is to confirm that the produced system satisfies all of the criteria that were established during the development of the business requirements.

It is carried out just after the System Testing and before the program is finally released into the actual world.

Some examples of functional testing

  1. User Login Testing: This tests the user login functionality, including valid and invalid login scenarios.
  2. Registration Testing: This tests the user registration functionality, including validation of mandatory fields, password strength, and email verification.
  3. Payment Gateway Testing: This tests the functionality of the payment gateway, including successful and unsuccessful transactions, handling of various types of cards, and security of sensitive information.
  4. Search Testing: This tests the search functionality of a website or application, including search results accuracy and performance under different conditions.
  5. Shopping Cart Testing: This tests the functionality of a shopping cart, including adding and removing items, updating quantity, and calculating the total cost.
  6. Order Placement Testing: This tests the functionality of placing an order, including shipping options, billing information, and confirmation of the order.
  7. Email Testing: This tests the functionality of sending and receiving emails, including attachments, spam protection, and email formatting.
  8. Data Integrity Testing: This tests the accuracy and consistency of data, including insertion, update, and deletion of data.

These are just a few examples of functional testing, but the specific tests you would perform would depend on the requirements and functionality of the software being tested.

Website Functional Testing?

Functional testing

A website’s functionality is tested using a variety of testing criteria, including user interface, APIs, database, security, client and server, and fundamental website capabilities. It is quite simple to do both manual and automated functional testing with functional testing. It is done to test how well each feature on the website works.

What methods of Functional Testing are there?

Functional testing is a type of software testing that focuses on verifying that a software system meets its specified requirements and works as intended. There are several methods of functional testing, including:

  • Unit Testing: This involves testing individual components or functions of the software to ensure they work as expected.
  • Integration Testing: This involves testing how different components of the software work together.
  • System Testing: This involves testing the entire software system as a whole to ensure it meets all the requirements and works as intended.
  • End-to-end Testing: This involves testing the software system from start to finish, simulating real-world scenarios, and checking for errors.
  • Acceptance Testing: This involves testing the software system to determine if it is ready for deployment and meets the expectations of the end user.
  • Regression Testing: This involves retesting the software after making changes or updates to ensure that the changes did not cause any unintended consequences.
  • Smoke Testing: This is a quick and basic test that is performed to determine if the software is stable enough to proceed with more in-depth testing.

Each of these testing methods has its specific objectives, techniques, and tools. The choice of method depends on the nature of the software being tested, the requirements, and the resources available.

Why Functional Testing should be a priority?

Functional testing is a crucial aspect of software development because it helps ensure that a software application or system functions as intended and meets the needs of its users.

It should be a priority because it helps to ensure the quality and reliability of software, meet user needs, comply with requirements, and ultimately save time and resources.

10 benefits of Functional Testing

Here are 10 benefits of using functional testing:

  1. Improved software quality: Functional testing helps to uncover defects and ensure that the software meets its requirements and works as intended.
  2. Better user experience: Testing the functionality of the software, it becomes possible to identify and address any issues that might negatively affect the user experience.
  3. Increased reliability: Functional testing helps to increase the reliability of the software by verifying that it behaves correctly under different conditions and inputs.
  4. Reduced downtime: Identifying and fixing defects early in the development process, it becomes possible to reduce downtime and minimize the impact of software failures.
  5. Increased efficiency: Functional testing helps to automate and streamline the testing process, resulting in increased efficiency and reduced manual effort.
  6. Improved user confidence: Conducting functional testing, it becomes possible to demonstrate to users and stakeholders that the software is robust and reliable, which helps to build confidence in the product.
  7. Improved product reputation: Delivering high-quality software, it becomes possible to improve the reputation of the product and the company that produced it.
  8. Increased customer satisfaction: Ensuring that the software works as intended and meets the needs of users, it becomes possible to increase customer satisfaction and foster long-term customer loyalty.
  9. Better risk management: Identifying and addressing potential issues early in the development process, it becomes possible to mitigate risks and prevent costly problems down the line.
  10. Improved development process: Incorporating functional testing into the development process, it becomes possible to continuously improve the software and refine the development process, leading to better results in the long run.

Functional testing for Mobile?

Functional testing

User interaction and transaction testing are typically included in the functional testing of mobile applications. Important considerations for this kind of testing include:

  • The type of application is determined by its operational capabilities (banking, gaming industry, social networks, and education).
  • The intended market (user, company, educational environment).
  • The method by which the application is distributed (for example, App Store, Google Play, or direct distribution).

Functional testing for Desktop?

Functional testing for desktop applications involves testing the application’s features and functionality to ensure that it behaves as expected. The purpose of functional testing is to validate that the software meets the specified requirements and functions correctly. This type of testing usually involves the following steps:

  1. Requirements gathering: This step involves understanding the requirements of the application, including the features and functions that need to be tested.
  2. Test case creation: This step involves creating a set of test cases that will be used to test the application’s functionality. The test cases should cover all the functions and features of the application.
  3. Test execution: This step involves executing the test cases on the application and verifying that it behaves as expected. Any errors or defects found during testing should be documented.
  4. Test result analysis: This step involves analyzing the results of the tests and determining if the application meets the specified requirements. If any errors or defects are found, they should be fixed and the tests should be rerun to confirm that they are now working as expected.
  5. Final release: This step involves releasing the final version of the application to the users after it has passed all the functional tests.

What are some Functional Testing interview questions?

Functional testing is the process of evaluating an application in light of the specifications in the requirements document, as the name implies.

Functional testing may be done manually or automatically, but both methods include evaluating the application by giving a set of inputs and identifying or confirming the result/output by contrasting the actual result with the intended result.

Most common interview questions for functional testing

  1. What do you mean when you say “functional testing”?
  2. What essential procedures are covered by functional testing?
  3. What makes functional testing different from non-functional testing?
  4. What distinguishes “Build” from “Release”?
  5. What various test techniques are employed in functional testing?

How to do Functional Testing?

Here’s a step-by-step guide on how to do functional testing:

  • Recognize the Functional Requirements;
  • In accordance with the requirements, determine the test input or test data;
  • Calculate the anticipated results using the chosen test input values;
  • Carry out test cases;
  • Compare the predicted and actual results.

What are some business benefits of Functional Testing?

To release a product that your end consumers would like, it is essential to test your company’s software. Functional and non-functional testing will make sure that your software is risk-free, secure, user-friendly, and simple to upgrade.

Additionally, it lowers the possibility that a significant software error may seriously harm your company.

There are several examples of how software errors have hampered corporate operations in the real world. Nissan removed nearly 1 million vehicles from the market in 2017 because the airbag sensory detectors’ software had malfunctioned.

Due to an unexpected breakdown of its POS (Point of Sale) systems, Starbucks famously had to close up to 60% of its outlets. Baristas were compelled to give away thousands of free beverages, much to the surprise (and joy) of consumers, costing the business millions of dollars in lost revenue.

How to do Functional Testing for a web application?

Any website has to go through testing before going live. Most experienced testers adhere to a set process since it aids in covering all angles.

  • Start the initial steps of functional identification;
  • Create or create the input data by the requirements;
  • Determine the requirements for the output-keeping function;
  • Start running the test case;
  • Examine the findings by contrasting them with what was anticipated.

How to do Functional Testing for a mobile application?

Any mobile app testing process must include mobile functional testing, which verifies that the program functions as it should. check for compliance with design and required standards.

Work together on the testing requirements

That is crucial. There can be no testing strategy without a clear understanding of what needs to be tested. Additionally, there should be no testing without a test strategy.

Although it might seem obvious, it is not the best practice to determine the needs in a vacuum. Which user instructions, integrations, procedures, and displays will be the most crucial will be known by the development team (and the Operations team in a DevOps situation). You may then begin to work on the test plan as a result of that collaboration.

Plan your tests and categorize them according to the importance

We occasionally observe this stage being completely skipped, which is unexpected and concerning. The test plan is not just a dull document where you list the things you already know.

It is a strategy for determining what you will carry out. Instead of writing down the exam strategy, the difficult part is usually the mental gymnastics that go into it.

However, in a nutshell, a best practice testing strategy should include the goals and parameters of the test, the resources needed for the test (including personnel, software, and hardware), as well as a test timeline.

Prioritize and rank the test cases that will be created as part of the strategy as well. Not all tests are equally important to one another.

Identify the automatable tasks

This might equally well be regarded as a component of the test plan creation. But it requires its section since it is so vital to testing and development techniques for mobile apps. Automate as much as you can, to put it simply.

Testing automation shortens the time to market while enhancing software quality. But be wise in your automation choices. This implies that you shouldn’t automate tasks that a manual tester might complete more affordably or efficiently.

Run your tests in actual user environments

More than any other sort of development, mobile app development requires that you discover a means to test in actual user settings. The consequences of losing data coverage or receiving an SMS are not something that web developers need to worry about, but you do.

Naturally, this increases the number of test instances, but that is the nature of mobile. Returning to the earlier discussion about test automation, having it in place will be quite beneficial as you begin to consider the functional requirements under various app scenarios.

Make it simple to submit your findings

The administration of outcomes ought to be one of the simpler aspects of the process, in principle. Although a lot of this relies on the test management systems you choose.

Abstraction and display of test results will be relatively simple with a modern test management system. It will be completed for you, and stakeholders will always have access to a dashboard.

In conclusion, functional testing plays a crucial role in ensuring the quality and reliability of a software product. By thoroughly testing all the functions and features, the development team can identify and fix any issues before the product is released to the market.

This not only helps to enhance the user experience but also reduces the risk of defects and improves the overall performance of the software. Effective functional testing requires a well-defined testing strategy, comprehensive test cases, and robust testing tools and techniques.

By following these best practices, organizations can deliver high-quality software products that meet the needs and expectations of their users.

Types of defects in software testing

In this article, we will talk about types of defects in software testing and how to identify them.

Software flaws can be detected throughout the entire process of developing and testing a product. Testers must have a solid awareness of the many sorts of errors that can emerge to guarantee that the most serious ones are addressed.

Let’s first understand what a defect is before we go further:

What is a defect in software testing?

A mistake, defect, malfunction, or fault in a computer program that results in an inaccurate or unexpected outcome or leads it to behave unexpectedly is known as a software defect. A software error occurs when the actual results don’t match the anticipated results. Sometimes programmers and developers make errors that result in defects, or bugs.

Software Testing defects

Software flaws come in a wide variety of forms, and testers must be conscious of the most typical ones to efficiently test for them.

There are three categories of software defects:

  1. Software Defects by its Nature
  2. Software Defects by its Priority
  3. Software Defects by its Severity

Types of Software Testing Defects by its Nature

There are many different types of software defects, and each has its own set of symptoms. Even if there are lots of these bugs, you might not see them frequently.

The most common software defects, those that are most likely to occur, are listed below and are categorized by nature:

Functional bugs

Functional bugs, as their name implies, are those that lead to problems with the software. A button that, when clicked, is supposed to open a new window but instead does nothing is a nice illustration of this.

Fixing functional defects

Functional testing can be used to address functional defects.

Unit Level Bugs

Defects that affect the operation of a single software unit are referred to as unit-level bugs. The smallest piece of a program that can be tested is a software unit. Classes, techniques, and procedures are a few examples of software units. Unit-level errors can significantly lower the software’s overall performance.

Fixing unit-level bugs

Unit testing can be used to address unit-level bugs.

Integration Level Bugs

Defects at the integration level appear when two or more software units are joined. These flaws can be challenging to identify and correct since they frequently call for cooperation among several teams. They may, nonetheless, significantly affect the software’s overall quality.

Fixing integration-level bugs

Integrity testing can be used to address integration bugs.

Usability defects

Usability bugs are flaws that negatively affect the software user experience and make it challenging to use. A software flaw that makes it challenging to use is known as a usability problem. Usability issues include those that make it difficult to use a website, navigate it, or complete the sign-up process.

Software testers look for these issues during usability testing by comparing programs to user needs and the Web Content Accessibility Guidelines (WCAG). They may, nonetheless, significantly affect the software’s overall quality.

Fixing usability defects

By conducting usability testing, defects in usability can be solved.

Performance defects

Performance defects are flaws that affect how well the software performs. This can include elements like the software’s speed, the amount of memory it requires, or the number of resources it needs. Because they can be caused by a variety of various variables, performance-level faults can be challenging to locate and resolve.

Fixing usability defects

Performance testing can be used to address defects related to usability.

Security defects

Software bugs of the security variety, if not fixed, might have serious repercussions. These flaws could provide hostile individuals access to delicate information or systems, or even give them control of the impacted software. Because of this, security-level issues must receive top-priority treatment and be resolved as soon as feasible.

Fixing security defects

Security testing can be used to address security defects

Compatibility defects

When an application is incompatible with the hardware it is operating on or with other software it has to interface with, it develops compatibility flaws.

Software and hardware incompatibilities can lead to crashes, data loss, and other undesirable behavior. Testers must be conscious of compatibility issues and conduct appropriate testing.

When used in conjunction with specific applications or when working under particular network settings, a piece of software that has compatibility issues does not function consistently on various types of hardware, operating systems, web browsers, and devices.

Fixing compatibility defects

Testing for compatibility can be used to fix compatibility bugs.

Syntax Errors

The most fundamental kind of defect is a syntax error. They happen when the code disobeys the programming language’s rules. An example of a syntax issue would be using wrong punctuation or neglecting to close a bracket. Since syntax problems typically prohibit the code from running at all, they’re rather simple to identify and correct.

Logic errors

Logic errors are flaws that lead software to provide false results. Because these issues frequently don’t generate any obvious faults, they can be challenging to identify and remedy. Any kind of software may contain logic errors, but such are most prevalent in programs that demand intricate computations or judgment calls.

Indicators of logic errors include:

  • Incorrect outcomes or results
  • Unexpected actions
  • Software freezes or crashes

Testers must have a thorough understanding of the program’s code and how it ought to function to identify and correct logic problems. The best method for locating these vulnerabilities is frequently to watch the program’s execution and look for errors using debugging tools or step-by-step execution.

Types of Software Testing Defects by its Severity

A defect’s influence determines its severity level. Therefore, the seriousness of a problem indicates the extent to which it affects the functionality or performance of a software product. Based on how serious they are, flaws are categorized as critical, major, medium, or minor.

Critical Defects

A software problem that seriously or catastrophically affects how the program functions are referred to as a critical defect. The application may crash, freeze, or behave improperly due to critical flaws. They might potentially cause data loss or security flaws. Because they must be corrected as soon as possible, developers and testers frequently give critical flaws the greatest priority.

Major Defects

A software bug that significantly affects how the application functions are referred to as a big flaw. Significant flaws can make the application run slowly or display other unexpected behaviors. They might potentially cause data loss or security flaws. Because they need to be corrected as soon as feasible, developers and testers frequently give major flaws a high priority.

Minor Defects

A software bug that has a minimal or inconsequential impact on how the application functions are referred to as a minor defect. The application may function a little bit slow or behave unexpectedly due to minor flaws. Since they can be corrected later, minor flaws are frequently given little importance by developers and testers.

Trivial Defects

A software problem that has no impact on how the program functions are referred to as a trivial flaw. The application may display an error message or behave unexpectedly due to trivial flaws. Because they may be corrected later, developers and testers frequently assign trivial flaws the lowest priority.

Types of Software Testing Defects by its Priority

Low Priority Defects

Low-priority flaws can typically be put off until the following version or release because they do not seriously affect how the software functions. This category includes grammatical and alignment issues as well as cosmetic problems.

Medium Priority Defects

Errors of a medium priority are those that might be resolved in a later version or after a current release. A medium-priority bug is one where an application returns the appropriate result but formats wrong in a particular browser.

High Priority Defects

High-priority flaws, as their name suggests, have a significant negative effect on how the product works. These flaws typically need to be corrected very away because they can seriously interrupt regular operations. High-priority flaws are typically categorized as “showstoppers” because they can stop the user from completing the work at hand.

These types of defects in software testing are inevitable facts. However, flaws can be handled to have a minimal impact on the finished product by careful investigation and comprehension of their nature, severity, and priority.

Testers can contribute to ensuring that errors are discovered and fixed as early in the development process as feasible by using the right questions and procedures.

Skills needed for being a good QA engineer

In this article, we will talk about the skills needed for being a good QA engineer.

It takes a long time to create a web page or application, and as it does, tests must be run to ensure that the code is written correctly and that the functionalities work as intended. A quality control engineer, or QA Engineer, is specifically responsible for this.

Table of Contents

Before we go further with this subject, let’s first understand what is a QA engineer:

What is a QA Engineer?

Every stage of the software development process, including design, development, testing, debugging, and delivery, is under the watchful eye of a QA engineer. They make sure the final product satisfies the demand and upholds the software’s quality standards at every stage.

The tests are also created by a QA engineer to ensure that the program is free of any technical flaws. They analyze data, find faults, and record findings while working in a lab or office environment in front of a system.

What is the role of a QA engineer?

Skills needed for being a good QA engineer

In an office, a QA engineer often works full-time. The majority of their work is spent checking the program for faults, making modifications, and making sure it complies with quality requirements. To test the program, they create test cases and record the outcomes.

Depending on the project they work on and the industry they work in, the QA engineer’s function may change.

A QA engineer is likely to carry out the following tasks on a weekly or even daily basis:

  • Establish guidelines and policies for developers to adhere to;
  • Conduct scripts for manual and automated tests;
  • Create and use automated testing;
  • Analyze test data to forecast user behavior, spot errors, and provide fixes to reduce issues;
  • To guarantee the project is delivered on schedule, he closely collaborates with the product development and testing teams;
  • Make sure the finished product complies with the criteria;
  • Analyze the aspects of the product and give suggestions for improvements to make them more effective and user-friendly;
  • Remain aware of the most recent standards, laws, and advancements in your sector.

Automation Testing

The process becomes simpler and more efficient if QA Engineers can develop software or service for the Project’s Software Quality Assurance Testing.

These are some advantages of automated testing:

  • Performance
  • Compatibility
  • Headless

The early phases of understanding automation testing may be difficult for engineers to understand. However, projects using automation testing have greater results.

Software Development Life Cycle (SDLC)

You must understand the Software Development Life Cycle if you want to be a member of the development and hiring team. To produce a successful project, businesses must go through several processes and combine them.

The following stages are necessary for an app or website development process:

  • Planning
  • Designing
  • Development
  • Software Quality Assurance Testing
  • Deployment
  • Maintainance
  • Evaluation
  • Disposal

Testing is only one stage in the Quality Assurance process. The development, testing, deployment, and maintenance of the website or app your business develops are all handled by QA Engineers.

After receiving client feedback and finding countless additional flaws and errors, they will test the project, approve it, then test it again.

Specifications for New Technologies and Systems

Consider that your QA Engineer is on route to use automation testing to find software flaws. They are utilizing computers and gear from the business. They are aware of software quality assurance testing, but they are not aware of how the system functions or changes.

How long do you suppose it will take them to restart several times? In addition, QA Engineers will revert to slower conventional approaches if they are unfamiliar with emerging technologies.

It’s also important to grasp computer-related developments, even if they have nothing to do with quality assurance testers.

Tools for test management and bug tracking

When hiring QA testers, businesses inquire about the testers’ familiarity with the following test management and bug-tracking tools.

Test Rail, Test Link, and Test Pad.

Proficiency in critical thinking and problem-solving

You should try out different approaches and try to work with them to discover answers to the errors you see in the Project as a recruiter for a Software Quality Assurance Engineer.

QA engineers will need to have a basic understanding of programming, as described in the section above. They may include the developers in the problem-solving process and come up with the best possible resolution to satisfy both the client and the business.

Project Administration

Project management skills are among the most important characteristics of QA engineers.

A QA engineer who can present the finished project to the firm and market is hired by businesses. They are accountable for the app’s performance and have to be prepared to make additional adjustments in response to requests from users.

Knowledge of the Project and the Domain

Consider that you are working on a global project. For the project for your customer, you are in charge of the development and software quality assurance tests.

Your QA Engineers are aware of their duties but are unclear about the Project, its specifications, and its objectives.

While doing tests as Quality Assurance Engineers, they give it their all, but since they lack project understanding, they lose out on some opportunities. How will it impact the outcomes of the app and your work?

All QA engineers need to learn about the origin and purpose of the project. Additionally, even after the Project has been released to the market, they should continue to monitor for updates.

Soft Skills that Make a Good QA Engineer

Skills needed for being a good QA engineer

In addition to great technical expertise, a specialist should also possess a certain set of personality traits that they may bring to the team. Employers will likely continue to appreciate and seek out the soft skills listed below in the future, in our opinion.

The issue is that active automation, which is now occurring in many industries, will greatly increase the value of soft skills. The duties that computers won’t be able to perform will need to be done by people.

On the one hand, there will be a rise in the demand for experts who can develop and manage automated systems. However, a majority of the duties that computers cannot complete are those that need soft talents.

Let’s start with a list of soft talents that are already advantageous for job seekers seeking QA positions:

Skills in communication

Everything depends on communication. The ability for transparent thought and expression is the key to productive teamwork. An in-depth explanation of the types of errors and the steps to recreate them must be provided by a QA engineer.

Both written and spoken communication is a part of it. Without accurate reporting, it would be challenging or perhaps impossible for the rest of the team to make modifications.

A personal approach

The concept of empathy is necessary for many different fields. Empathy is essentially the ability to understand people and put oneself in their shoes. In QA and software testing, empathy is the desire to understand the objectives of the client and share their viewpoints.

You’ll be able to ask the proper questions and offer your ideas in a way that can improve the final result if you’ve managed to determine what the client’s priority is.

A skill in analytics

In their regular job, QA professionals analyze software products’ features and behaviors to look for systemic faults. The ability to acquire and interpret information is the basis of such activities.

An analytical skill set includes logical thinking, critical reasoning, inquiry, data analysis, creativity, and problem-solving.

Detail attention

A QA engineer must be aware of subtleties and issues that are almost impossible to identify. It’s a careful task that calls for a lot of focus and some skepticism.

One can locate weak places in a generally reliable system by paying great attention to the details. Even if there aren’t any obvious errors right now, it promotes double-checking those areas that are often prone to flaws.

Aim for quality

A QA team may be pressured to examine complex features fast when the deadlines are short. Even under these circumstances, one should be conscious of the impact on quality and communicate their thoughts to a consumer.

A QA engineer’s job is to fully inspect a product. The time needed to do this must be accurately estimated, and the client must be informed. Always remain aware that quality assurance is your main goal and should come first.

Ability to reason

A thorough technical comprehension of the processes is necessary for reasoning. You should provide pertinent justifications when outlining to other team members why a certain method is necessary.

You should never say to a customer, “We need to do performance testing because it will be better this way,” or anything similar.

Every piece of advice needs to be supported by solid data. It’s crucial to be able to explain complicated concepts in a way that non-technical people can understand.


Many careers need patient labor and a commitment to learn and advance professionally. Without work and diligent study, it is difficult to become good at what you do. IT personnel should keep up with new trends and best practices as technology develops.

A person’s worth as a professional increase if they like going to events for their industry, developing their hard skills, keeping up with business news, etc. However, being limited to a single product makes it difficult to progress professionally.


There are people with extraordinary skills and expertise who find it difficult to collaborate with others. Collaboration is a key component of software testing.

Customers are still expected to cooperate closely with stakeholders and developers even if they just need one professional to work on a project. Too much reliance on one’s abilities might have an impact on the outcome. Smooth cooperation is even more crucial when many QA professionals are working on a project.

Does learning to code make you a good QA Engineer?

Learning the principles of programming may assist QA engineers to create automated test suites that would save time on manual testing and give them a better grasp of how software developers apply their development strategies.

The programming languages Java, C#, JavaScript, and Python are some of the most popular ones to learn.

Does becoming a good QA engineer require a degree in computer science?

Since many organizations still favor a degree, having a degree in computer science might help you land your first Quality Assurance position. That could be an option worth considering if you have the time and resources to go down that road.

Do you need to be certified to work as a QA Engineer?

QA certificates can improve your knowledge base and career. You do need to have a degree from an approved university or a few years of experience for several of these certificates.

If you are in search of a QA certification, take a look at this article, where you can find information about QA testing certifications.

How to apply for QA engineer positions

You can begin looking for junior-level opportunities once you have mastered the foundations of programming, testing, and quality assurance. Build a solid resume, and use the free online interview preparation resources to get ready for the QA interview questions.

It would be beneficial to have some experience through modest contract work if you are self-taught. Students will get access to internship opportunities and other career resources if they are enrolled in a degree program.

Those are some of the skills needed to be a good QA engineer. Hard skills undoubtedly form the core of a QA engineer’s skill set. However, a person’s soft talents are frequently what makes them a valued asset to a team. Typically, it is simpler to impart theory to beginning experts and to spend time monitoring their work than it is to build and nurture crucial soft skills. A QA expert should have a blend of hard and soft abilities and continually work to improve both.

bookmark_borderRegression testing

In software testing. regression testing is any type of testing that seeks to uncover new software bugs, or regressions, in existing functional and non-functional areas of a software application. A regression is defined as the reappearance of a previously fixed software bug. In order words, it is a change in the software that causes previously working features to stop working as intended.

It is carried out to validate that changes (usually bug fixes) have not introduced new bugs. It is often done after the execution of unit tests and integration tests.

What’s UX regression testing?

When a design deviates from an established workflow due to a technology or complete redesign, UX regression, or a step back in the quality or usability of an application’s or website’s user experience, can happen.

What are the 3 types of regression testing?

Regression testing
  • Unit regression

To enable independent testing of the unit without inconsistencies, the code you test in isolation during the unit testing phase forbids any dependencies on the unit you tested.

  • Partial regression

To ensure that the code still functions properly after you made modifications and you merge the new unit with older or existing code, you use partial regression.

  • Complete regression

You can use complete regression when numerous modules are impacted by a code change and it is uncertain how one module’s alteration will affect another. To see if the altered code has caused any modifications, you can revert the entire product.

What types of regression testing are there?

There are various types and formats for regression testing. How do you choose the right one for you? Consider your software development life cycle as well as any particular upgrades you intend to roll out.

Unit Regression Testing

This test focuses primarily on a number of variables, several recurring flaws, and the importance of particular aspects under examination. The primary goal of this test is to produce a useful piece of code that improves and provides value to the program as a whole.

Corrective Regression Testing

When there have been no relevant modifications made to the product’s specification, you can use this sort of regression testing. Additionally, there is no need to create any new test cases because it is possible to reuse the ones that currently exist to conduct tests and ultimately arrive at the required outcome.

Selective Regression Testing

This regression test makes sure that you use the test case’s existing portions. This saves time and effort from having to create a new test case from scratch, as well as lowering the cost of retesting.

Reset all test case

Given the lost time, reset all the test case can be quite tiresome. When only injected a small change into the existing product, this type of test is not advised.

Progressive Regression Testing

When there are little modifications made to the program specifications and you create fresh test cases, you can perform the regression tests.

Complete Regression Testing

The best regression testing to use if significant changes appear in your test code is this one. You can use this primarily when the software’s root code undergoes a significant modification. This aids in resolving unforeseen problems and serves as a final test before delivering the application to the user.

Partial Regression Testing

You can perform partial regression testing as and when you include new codes in an existing piece of code, as the name implies. The main goal of this test is to confirm that the system is operating in the same manner as it did previously.

What isn’t regression testing?

Regression testing is often mistaken for a retest, which is one of the biggest errors businesses make. Simply inspecting and making sure that certain portions of the code are in line with expectations is what the retest entails. On the other hand, it makes sure that the whole system can meet the criteria before release, ensuring that no new flaws are introduced.

Some examples of regression testing

Regression tests have many different uses. Let’s look at the most well-liked list examples:

  • Bug regression: A tester verifies if a particular bug that has been purportedly fixed has been fixed.
  • General functional regression: Several thorough tests across the entire app to check whether recent changes have caused code instability.
  • Conversion and port testing: To confirm that the program has been effectively transferred to a new platform, a suite of test cases is run.
  • Localization testing: If a program has been altered and rewritten in a different programming language, a tester evaluates the interface’s usability and makes that the program adheres to its new cultural norms.
  • Build verification testing: A series of quick tests to determine whether damage to a build is fixable or not. A build would be rejected if a test failed.

Let’s use “Login Functionality” to explain regression testing:

  • Utilizing their login and password or their Gmail account via Google integration, a user can sign into an app.
  • Users can now log into the app using their LinkedIn account thanks to the addition of a new feature called LinkedIn integration.
  • Verifying that other login methods are still working is just as important as making sure the LinkedIn login works as planned (Form login and Google integration).

Website regression testing?

Regression testing for websites is a type of software testing that aids in finding and fixing issues with website functionality, content, and accessibility. It is an essential component of any testing plan because it may help guarantee that the website keeps up with user expectations.

Regression testing for websites often entails running several tests against the website to look for any problems. Testers on the development team can run those tests or automatically through an automated system. This makes it possible to identify issues precisely and quickly so that they can be rectified before spreading widely.

What methods of regression testing are there?

Regression testing
  • Retest all

You must execute all the test cases in your test suite again in the retest. In comparison to other regression testing methodologies, this method is more expensive and time-consuming.

  • Regression Test Selections

In the test selection technique, you must choose the test cases from your test suites that you will use, while taking into account the code change in the module.

  • Test Case Prioritization

You must rank the test cases in order of top, medium, and low priority according to the significance of the functionalities. Then, according to priority, you can execute these test cases.

  • Hybrid

It combines the selection of regression tests with test case prioritization.

Why regression testing should be a priority?

To ensure that the unmodified code is not impacted, this is a quality control measure to see if the new code is compatible with the older code. The testing team is typically tasked with verifying any hurried system changes.

In this instance, it is necessary to conduct testing that only impacts the application area in order to complete the testing process on time and thoroughly test all significant system components.

When the program is constantly changing or being improved, this test is crucial. The tested code already in place shouldn’t suffer from the additional functionality.

Finding the bugs that appeared as a result of a code update necessitates regression. Without this testing, the product may experience serious problems in a real-world setting, which could put the client in danger.

10 benefits of regression testing

We listed the different benefits of the Regression test below:

  1. It raises the level of product quality
  2. It guarantees that any bug patches or additions made do not affect the product’s current functionality.
  3. This testing can be done with automation tools
  4. It will guarantee that already-fixed problems don’t come up again
  5. Helps keep the technology up to date
  6. Aids in developing an appropriate method for automating the recording of GUI responses
  7. Greater test coverage with shorter test times
  8. Sooner learn about troublesome bugs
  9. Improve efficiency and cost-effectiveness
  10. While continually improving the application, it maintains system stability

Regression testing for Mobile?

It’s essential to realize that the regression testing of mobile applications and online apps doesn’t differ much. No matter the platform, the app’s functionality will remain the same. For instance, the Facebook “Like” button will behave equally on both the online and mobile platforms, ensuring consistency in functionality.

Therefore, there isn’t much of a distinction between regression testing for mobile and regression testing for the web.

Regression testing for Desktop?

Regression testing is a sort of software testing used to find new bugs, or regressions, in desktop programs that have been introduced as a result of patches, modifications, or enhancements. As soon as there is a testable component, desktop web regression testing begins. Additionally, this kind of testing finds bugs or regressions that may have appeared in the system as a result of code alterations, which aids developers in creating properly working desktop applications.

What are some regression testing interview questions?

The interviewers usually ask these questions:

  1. What is Functional Testing?
  2. What is Regression Testing?
  3. Is Regression Testing done either manually or automated?
  4. How to perform Regression Testing?
  5. What are the steps involved while performing the Regression Testing?
  6. Why is Regression Testing beneficial for IT industries?
  7. To what extent is Regression Testing needed?
  8. What are the most common types of Regression Tests?
  9. When should you perform Regression Testing?

How to do regression testing?

It is best done by developing a plan early in the development process and sticking to it until you release the product. The good news is that creating a testing framework is not too difficult. Here are the steps that QA experts use:

Assemble tests for use

Gathering all the cases a QA expert plans to re-run is the first stage in creating a regression testing approach.

  • Include examples in the program’s error-prone locations since such parts are probably the most susceptible to system changes.
  • Include scenarios that test the product’s primary features. The home page, the login page, the payment gateway, and so forth are all examples of this.
  • Include challenging situations like GUI event sequences.

Calculate the time required to run the test cases

Make sure to include the time required to test each feature you have selected. Keep in mind that, aside from a session, your testers may need to arrange some time to learn the variety of tools required to perform and report certain tests.

  • Generating test data;
  • Preparing regression tests;
  • Reviewing test cases.

List the tests that you can automate

Compared to manual testing, automated ones are quicker and more trustworthy. Long-term, you’ll be able to utilize these scripts again for your subsequent projects, which will increase the effectiveness of software maintenance and establish a set of guidelines within the team.

Make test cases a priority

It’s usually beneficial for a tester to identify the cases that are most pertinent to the program and concentrate on running them as a top priority. Setting priorities is essential for good session management.

Utilize tools to accelerate the testing procedure

You can do regression testing with a variety of tools that assist QA professionals with planning, preparing, and reporting. The team may expedite the procedure and apply regression testing best practices by using these off-the-shelf products.

How is regression testing performed?

First and foremost, there are a few prerequisites that you must meet for a regression test so that you can perform it.

First, there must be indications that the code is broken.

Once you verify the complaints and you locate the problematic code, it is further dissected to determine how and why the issues exist. Taking the necessary action to modify and repair the harmed sections would be the logical next step.

The next action would be to run the Regression test as soon as you solve all bugs and issues. You can accomplish this if you select and execute helpful tests. In this instance, there are two categories for the tests.

  1. tests that include a cross-check for each altered section of the code.
  2. tests for the regions most probably impacted by these changes.

How to prepare for regression testing

Determine whether regression testing is necessary

Finding a requirement for software regression testing is the first step. You should use the regression testing approach as soon as you change the program. With the use of regression test scripts, the main goal of this testing method is to evaluate the software’s current functions.

Start with smoke and sanity testing

You should carry out smoke testing and sanity testing to save the tester time and effort, even before the regression testing procedure has started. The software’s fundamental and essential functions are swiftly examined during the smoke and sanity testing to make sure they function properly. It enables testers to determine if a build is safe or not and whether to push it forward for additional testing procedures.

Set entry and exit standards

It is crucial to establish the admission and exit criteria before the exam even begins. The test goals and test requirements should be in harmony at the entrance and exit locations. Determining the entry and exit locations so facilitates the testing procedure.

You should prepare and prioritize the following key testing situations

The software’s problematic parts and the parts that you must evaluate first should be identified by testers. Additionally, test case preparation and prioritization should revolve around troubled issues.

Automate regression testing

To complete a regression testing cycle, testers should determine the test cases that they can automate. You can use tools to evaluate the program by automating regression testing. Better test coverage, early problem identification, quicker releases, and time and effort savings for testers are all benefits of test automation.

Keep the regression test suite repository

Testers should keep the regression test suite in a repository. Testers should write the appropriate test cases and contribute them to the repository as early as any modifications are made to the product.

Additionally, you must clean the repository must of old test cases.

Obtain feedback from key stakeholders

You need to inform all stakeholders, including development teams, of the test plan after you created it. Additionally, it’s important to periodically gather input from team members and stakeholders to adjust the regression testing strategy as necessary to achieve meaningful findings.

What are some business benefits of regression testing?

Here are some benefits for businesses by adopting an effective regression testing strategy:

Identifies bugs and fixes them

Every time you make a change to a piece of software, there is a potential that it will create new problems or resurface flaws from the past.To find and fix the defects that appear in software following frequent code changes, an efficient regression testing procedure supported by a sound testing strategy is necessary.

Decreases testing costs and time

An efficient regression testing plan makes sure that you finish the tests as quickly as possible so that organizations may enter the market. An effective testing procedure makes sure that the previous issues do not reappear, avoiding the expenses of bug fixes.

Channels the efforts of the testing team

A solid testing plan guarantees that QA teams remain motivated and are current on the testing material, eliminates ambiguity, and specifies the responsibilities and duties of testers. It makes sure that the team is focusing their testing efforts in the right way to provide successful testing outcomes.

Easily handles testing complexity

Regression testing typically expands and becomes more intricate with time. You can use a sound regression testing approach to manage and handle complicated test suites more effectively.

Ensures optimal use of resources and testing equipment

Regression testing strategies should be carefully planned so that the teams are aware of their roles and duties in advance. You can plan appropriate regression testing techniques and resources to maximize advantages.

How is a manual regression testing strategy put into practice

No matter how adept you are at automation, manual regression testing is still necessary.

Decide on your regression testing plan

The first step is to make a pretty straightforward decision: Will you retest your whole program for this round of regression testing, or will you solely concentrate on affected regions and known trouble areas?

Specify the changes that you made to the product

You need to list the product changes that you made after that. To comprehend the nature of the most current upgrades, speak with the product manager.

Think about what other features such improvements could have impacted

You may want to verify various account organizational settings, user profiles, admin and rights settings, etc., for instance, if your app switched from supporting two-factor authentication to multifactor authentication.

Select the extra testing components or known issues areas that you will use

Is there anything wrong with your app? Exists a feature that frequently breaks and attracts a disproportionate quantity of support requests and QA-found bugs?

Control the testing area by dividing it apart

You should use test management tools, such as TestRail or JIRA, to divide up your extensive running list of things to test into individual test cases and exploratory test prompts.

Create bug reports that include reproducible instructions, images, and videos

The ideal bug report contains the feature name, the environment, the necessary procedures to replicate the issue (extra points for screed captures and screen-sharing videos), the intended results, the actual outcome, and the issues’ presumed importance.

Utilize testing resources to confirm testing coverage

You must then validate with your team what was covered when all testing is finished. Verify that everyone in your manual test management platform recorded their assignments as completed.

Keep and reuse your test cases

Review your exploratory test prompts and test cases from this round and determine how they fit into your broader regression testing approach.

How to do regression testing for a web application

No matter what operating system or browser is used to access your application, your consumers want a consistent user experience. They also anticipate that once a feature is in operation, it will remain in operation. Regression testing makes sure that any new code doesn’t break any of the application’s already-existing features or functionalities and that it keeps running on multiple platforms.

The user’s needs, for instance, can consist of:

  • The visual design of the application remains constant throughout
  • The functioning of the app is as expected
  • Different systems and browsers are supported by the application
  • Incorrect input is not tolerated

The implementation of these standards necessitates a thorough testing strategy. As you can expect, preventing regressions throughout your whole program necessitates a lot of testing.

To begin, you will want a fundamental set of end-to-end tests to guarantee that your most crucial user flows are covered. To capture the application functionality that has been introduced to the program over time, you need to create additional tests. Adding new functionalities tests to a regression suite that develops over time is an excellent technique to create your regression suite.

How to do regression testing for a mobile application

Before starting the testing of the mobile application, several factors need to be taken into account:

  • The app’s effectiveness when interrupted
  • Proper app installation on a different mobile OS version
  • Application usability about user needs
  • The navigation and layout are user-friendly
  • Consistency in landscape and portrait modes

Mobile testing is now more important than ever because of the rising demand for mobile applications. Making mobile testing more rigorous has become crucial given how quickly smartphones are developing.

The following guidelines must be followed while testing mobile applications for regression:

  • Select smartphones based on the usage habits of your target market
  • To do testing more quickly and automate testing, use emulation and simulation
  • A mobile app’s price and delivery time can be decreased when it is tested in the cloud

These are some of the most important details that you need to understand, Your choice will determine whether or not your testing process is successful. As a result, you must take every step very seriously.

After reading this guide, you should now have a clear understanding of what regression testing is, what it’s used for, what the benefits and limitations are, and how to go about conducting regression tests on your software.

By following the tips in this guide, you can be sure that you’re doing everything you can to ensure the quality of your software before release.

Usability testing

Usability testing is the process of assessing a product using real users. Usually, participants will attempt to execute standard activities during a test while observers watch, listens, and take notes.

This study aims to evaluate the product’s usability, gather qualitative and quantitative information, and assess participant satisfaction.

What’s UX usability testing?

UX (user experience) is fundamental to a product’s success, therefore it’s critical to put the user at the forefront of all design and development decisions from the start. A product must fulfill end-user needs in a way that is intuitive, simple, and elegant. Just meeting those goals is not enough. Every product must provide an outstanding user experience.

A vital part of good user experience design is usability testing. It enables you to test hypotheses, support research, and prevent unpleasant shocks or disappointments during late development or go-to-market. The only way to ensure that a product will deliver what customers are ready to pay for is through usability testing.

What are the 3 types of usability testing?

Moderated testing: In this type of user testing, a moderator who is knowledgeable about facilitation, quality assurance, and the product itself guides testers through test cases. In addition to collecting end-user input, the moderator will also compile comments and observations. Moderated testing can be done in person or remotely.

Usability Labs: Usability labs are planned events when end-user testers are hired and pre-defined testing is carried out on certain functions. Using qualitative and quantitative techniques, end-user preferences and behavioral information are acquired throughout these testing sessions. Usability labs need more preparation, but the results are more thorough and comprehensive.

Guerilla Testing: This kind of testing involves approaching potential end users and asking them to participate in a brief (10–15 minute) sessions that are focused on certain test cases or objectives. Testing costs are often low since guerilla testing may be as informal as approaching people in a coffee shop. The breadth, extent, and focus of the input, nevertheless, might vary.

What types of usability testing are there?

The primary usability testing techniques are briefly described in the section below:

Hallway Testing

This type of testing implies the use of random people to test the website instead of using experts who have experience and training in website testing.

Remote Usability Testing

You can test a website’s usability testing using users from different nations and time zones. Occasionally, you can use video conferencing for remote testing, while other times, the user and the evaluator work independently.

Expert Review

A professional in the area is consulted to assess the website’s usability. When evaluating a site, the expert may be brought to a testing facility or the testing may be done remotely with automated findings for review.

Paper Prototype Testing

Simply said, this usability testing technique entails producing rough, even hand-sketched, interface designs that you can use as prototypes or models for a design.

Questionnaires and Interviews

Interviews allow the observer to pose direct questions to the participants because they are one-on-one encounters. Similarly, using questionnaires, the observers can pose questions.

Do-it-Yourself Walkthrough

In this method, the observer creates plausible scenarios to simulate a usability test, as the name suggests. Then, just like a user, they proceed through the process themselves.

Controlled Experiments

A strategy that resembles scientific research and usually entails a side-by-side evaluation of two items and meticulous statistical balance in a lab.

Automated Usability Evaluation

To automate online usability testing, you can create numerous research papers and prototypes, all with varying degrees of success.

What isn’t usability testing?

The techniques listed below are not categorized as usability testing:

  • A/B testing: In contrast to usability testing, which looks at user behavior, A/B testing involves comparing various iterations of a website to see which performs best.
  • Acceptance testing: Acceptance testing is a technical test for quality assurance, not an assessment of how user-friendly and effective the product is.
  • Focus groups: When doing a focus group researchers assemble a small group of people to talk about a certain subject.
  • Surveys: Surveys are a tool for measuring user experience and can be employed in conjunction with usability testing to get user feedback.
  • Heatmaps: Heatmaps are a wonderful way to watch and objectively measure behavior on your website, but since they report on user behaviors on average, they aren’t exactly usability testing.

Examples of Usability testing

Here you can find some real-world examples of usability testing:


Movista is a workforce management program used by manufacturers and retailers’ suppliers. A smartphone app, aids users in planning and carrying out duties both in-store and out in the field.


Movista is poised to introduce new messaging, chad, and announcements offerings as a part of a broader redesign of its entire platform. This will improve communication between those working in-store and those out in the field.

Usability testing strategy:

Due to the late stage of the development of Movista’s new communications function, they tested a high-fidelity prototype.

They conducted these tests to address any remaining usability problems, which can be more difficult to spot during the process.

They aimed to obtain more statistically significant findings to confirm their designs before launch by conducting the test on a larger sample size. The fundamental structure of the usability test involved giving participants a fairly precise task to complete before asking them an open-ended question about their experience.

The group would rank people’s comments and then consider alternative options if there was a steady demand for them.

They ultimately decided to move the stage of picking a recipient to far earlier in the process based on the insights they gained from the final findings and feedback.


One of the biggest fast-food restaurant businesses in the world, McDonald’s serves an astounding 62 million people per day. McDonald’s, however, was slow to adopt the mobile revolution as its app for smartphones just debuted in August 2015.

In light of the opposition, McDonald’s needed to catch up. They chose to work with UK-based SimpleUsability before releasing their app in the UK to find any usability issues. Twenty usability tests were to be conducted as part of the test strategy, with task scenarios that spanned the whole customer experience from beginning to end. 225 end-user interviews were included in the test strategy.

Several usability problems were found during the investigation, including:

  • Poor call-to-action button display and functionality

  • The overall user experience was hampered by the absence of order personalization and favoriting


With more than 175 million unique monthly listeners, SoundCloud is the top music and audio distribution network in the world. To continuously test the usability of the SoundCloud mobile app, SoundCloud recruited test IO, a usability testing company with offices in Berlin.

SoundCloud’s strict development schedule necessitated the necessity for ongoing human user testing to guarantee that all new upgrades function properly on all devices and OS versions.

The main goals of SoundCloud’s ongoing usability tests were to:

  • Offer mobile app users a user-friendly listening experience
  • Find and fix software bugs before the general release
  • Streamline the process of creating a mobile application

They found over 150 usability flaws, including 11 critical ones, in the initial usability assessments. Internal bug testing probably wouldn’t have uncovered these problems. This is because they used users from a variety of devices and locales to test the software.

A testing scale this vast would have been exceedingly costly and challenging to accomplish without remote usability testing.

Halo: Combat Evolved

The first video game in the wildly popular Halo franchise was “Halo: Combat Evolved.” Within ten years of its release, Microsoft was able to sell more than 46 million copies of the Halo video games worldwide, contributing to video game and hardware revenues of more than $5 billion.

The Halo team assembled a group of console gamers to test the prototype of their game to see if they enjoyed playing it. And if they weren’t having fun, they were interested in finding out why not.

They placed the test participants in a sizable outdoor environment for the usability sessions, where opponents were waiting for them on the other side of the open area.

What the designers of the game expected:

They expected that when players sprinted closer to the adversaries, major combat rife with excitement and action would ensue.

What happened:

The test subjects would maintain the greatest possible distance from the adversaries and fire from a distance across the outdoor area rather than placing themselves at risk by moving closer. Although it was a secure and successful technique, the players found it to be quite dull and uninteresting.

The solution:

To warn players when they were too far from adversaries, the aiming indication in the center of the screen changed in size and color.

Website usability testing?

Website usability testing is the process of assessing your website’s functioning and design by watching visitors’ actions and behavior while they carry out particular tasks.

What methods of usability testing are there?

Moderated + in-person usability testing

The most control is provided in-person, moderated tests. They require a lot of resources, but they are great for gathering comprehensive data.

  • Lab usability testing: This kind of usability testing is conducted inside a lab that has been specially designed for it. While a skilled moderator watches and observes, test participants work on computers or mobile devices to accomplish tasks.
  • Guerilla testing: In this type of testing, people are randomly selected from a public area. They are requested to do a brief usability test in return for a gift card or another kind of reward.

Moderated + remote

You need a skilled moderator to conduct moderated and remote usability tests, using a computer or phone.

  • Phone interviews: In a phone usability test, the user’s online activity is remotely recorded while the moderator gives participants spoken instructions on how to accomplish tasks on their computers and gather information.
  • Card sorting: It involves writing topics on digital note cards and letting people organize and categorize the cards. They discuss their reasoning in a debriefing session led by the moderator after sorting the cards.

Unmoderated + remote

These passive testing methods, which mainly rely on computer programs, shed light on how people interact with a website in its “natural habitat”.

  • Session recording: This type of usability testing is using software to capture behaviors like mouse clicks, movement, and scrolling from actual (but anonymous) users.
  • Online testing tools and platforms: Numerous online testing tools enable you to observe user activity on your website from a distance. Some of those platforms let you pay participants to take quick tests, while others keep an eye on the actions of actual users as they navigate your website.

Unmoderated + in-person

You can administer unmoderated in-person tests in a controlled physical environment without a test administrator.

  • Observation: Researchers can observe participants’ facial expressions and body language during observational testing without the moderator’s involvement.
  • Eye-tracking: Using a specialized pupil-tracking gadget attached to a computer, researchers track and analyze users’ eye movements during eye-tracking testing. The computer can produce heatmaps or movement pathways diagrams by examining where users focus their attention when asked to perform a task.

Why Usability testing should be a priority

The danger of creating the incorrect product is decreased by conducting usability testing properly, when necessary, with the appropriate group of individuals, saving time, money, and other valuable resources. In other terms, if done early on, when the product is still in the paper prototyping stage, it identifies issues when they are simple and inexpensive to resolve. Additionally, when carried out on a mature product, it aids in understanding user success rates and the time required to perform tasks.

10 benefits of usability testing

Your close familiarity with your website or app may make it difficult for you to spot some usability difficulties that unbiased users from the outside may notice—helping you identify problems that you might have otherwise overlooked.

Using usability testing can help you to:

  1. Validate your prototype
  2. Make sure your product lives up to expectations.
  3. Determine the problems with complex flows
  4. Additional numerical data points
  5. Detect small mistakes
  6. Develop compassion
  7. Get buy-in for change
  8. Improve the user experience
  9. Saving money
  10. Save time and resources

Usability testing for Mobile?

Mobile app usability testing involves evaluating a mobile app’s usability on actual users. It demonstrates how simple the mobile application is to use and explains how it can better assist a brand’s main marketing goals.

Usability testing for Desktop?

You can do desktop application usability testing to uncover faults and defects in software and identify areas that you need to strengthen.

What are some Usability Testing interview questions?

There are basic questions that can be useful in every testing scenario, even though each case necessitates a new collection of usability test questions.

The following are three major categories of user testing inquiries:

  • Screening questions: a set of inquiries designed to assess a test taker’s qualifications.
  • In-test questions: a sequence of inquiries focused on your test objective. There are both general and particular inquiries regarding your product in the in-test questions.
  • Post-test questions: a series of inquiries you make after the meeting. These could involve elaborating queries.

How to do Usability testing?

A researcher (referred to as a “facilitator” or “moderator”) encourages a participant to complete tasks during a usability-testing session, typically utilizing one or more particular user interfaces. The researcher monitors the participant’s behavior and hears feedback as they complete each task.

How is usability testing performed?

Here are five steps on how you can perform usability testing

  1. Make task analyses and metrics decisions

You must first determine your metrics. Usability testing can reveal a wide range of problems, but if it isn’t targeted to identify particular metrics, it won’t be a good use of your time or money.

  1. Choose the ideal test type

Usability testing comes in a variety of shapes and levels of effort and expense. The measurements and activities you developed in the first phase will determine the type of test that works best for your website.

  1. Locate Reliable Participants

A UserTesting poll found that 41% of businesses hire between six and ten users, while 33% hire five or fewer.

  1. Decide When, Where, and Who

The decisions you have to take from here are:

  • Remote or in person
  • Moderated or unmoderated
  1. Repeat

Even though there is some debate regarding its contribution to innovation, iterative testing is the secret to great usability. What does iteration in the context of design mean? It implies that your work is never over; after developing a website, you continue to

How do you prepare for usability testing?

Recruiting people, assigning team roles and tasks, preparing or utilizing other forms, producing questionnaires, using standard post-test questionnaires, designing or using qualitative feedback methods, and testing the test are some of the actions involved in preparation for usability testing.

What are some business benefits of usability testing?

You can develop your product to provide an ideal user experience the more knowledge you have about how your users interact with it.

The following are some of the main benefits of usability testing in the creation of apps:

  • Save a ton of time and money: You may check that your app works properly and that its primary features are clear to use by conducting user testing. As a result, you may quickly find and fix problems with the user journeys early in the initial design rather than investing in a final project that doesn’t work out.
  • Find excellent opportunities: More than ever, they want convenience. If the possibility exists, users who wish to acquire a specific product through their app but are unable to do so because the ordering process is flawed or complicated would undoubtedly order it from a rival. You can find user annoyances through user testing that otherwise would go unnoticed.
  • Assure ease of use: Even though participants have no trouble using the application, a usability test can show how long it took them to figure it out if they ran into any problems, and how many steps they had to take to complete a particular task.
  • Obtain a significant competitive advantage: With so many applications available, you will need to go above and beyond to give your consumers an app they will select over another. The development of a product that goes above performance and gives a much-improved user experience is aided by usability testing.

How to conduct usability testing?

With the aid of this strategy, you can comprehend how simple it is for a user to utilize the application, how adaptable it is with controls, and how capable it is of achieving its goals.

Here are some steps on how to conduct usability testing:

Create the objective and purpose

Ask yourself what the test’s purpose is before you begin the actual testing. Is it the gathering of user data or the verification of user behavior when using the interface? The testing format will be determined by the purpose.

Select the test method

Select the testing technique that best fits your product taking into account the budget, people resources, and stage of product development.

Create the test strategy

Establish the testing process’s objective to keep the goals succinct.

List the queries and assignments

After the strategy has been decided, it is time to get ready for the test itself. Give the users a list of the responsibilities and inquiries that will help them get there.

Select a location and space

Consider the ensuing organizational issues:

“Where will the testing take place?”

“Will the testing be held online or onsite?”

Select the moderator

Select a person who interacts with the user and controls the entire testing procedure, leading the user every step of the way.

Determine the collaborators, helpers, and observers

Engage assistants, observers, and collaborators who can help you conduct the test in an objective and transparent manner for full efficiency.

Locate and select the participants

Decide who your target market is, then choose groups of users to test the product with. Ensure that you hire individuals who are not involved in product development. You’ll require 5-7 users.

Assemble the test materials

To perform the test, assemble the testing prototypes.

Hold a short warmup

By enquiring about their expectations for the project, you can try to break the ice.

Give users an assignment and a goal

While you shouldn’t try to sway the user’s opinion of the product, you should make sure they are fully informed of the objectives and tasks they must accomplish.

Keep an eye on how the consumer uses the app

Testing serves a purpose that goes beyond merely achieving objectives. Another important factor is how the user navigates the app flow.

Summarize the user’s experience

Gather the testing data so that you can further evaluate it with product managers and designers.

Analyze data and observations

Be prepared for unforeseen test findings. Analyze the data, and prepare to make significant adjustments to the current products.

How to do usability testing for a web application?

If your main method of doing business is online, your website is your online real estate. However, the likelihood of a bad user experience increases if the website doesn’t follow contemporary web design principles. The usability and intuitiveness of your website should be excellent regardless of how or why users go there.

QAs put a website through several user scenarios that are likely to be encountered when using it as part of online usability testing or web usability testing. It entails carrying out several user behaviors that new website visitors typically take.

Another QA observes user actions as they are being carried out to assess how usable the site is. Feedback is given right away since any problems that arise throughout the testing process can be seen and noted by the observer right away.

How to do usability testing for a mobile application?

Usability, according to research, is crucial to the success of mobile apps. In reality, a recurring theme across popular mobile phone applications is that users tend to think of them as simple to use, user-friendly, and quicker to complete tasks.

Mobile application usability testing can be done using one of two main approaches. Each has advantages and cons of its own, as is obvious. Which are:

  1. Laboratory-based usability testing
  2. Remote usability testing

The “Components” of a usability test conducted in a lab

In lab-based usability assessment, test subjects are observed as they complete prescribed tasks on a mobile device.

The Test Method

The testing process can be divided into the following six steps:

  1. Welcome and sign the permission form
  2. Preliminary interview
  3. Completing the test requirements
  4. A post-test survey
  5. Interview after test
  6. Debriefing

It’s critical to remember that usability testing is more than just a task to cross off the project schedule. The team should have a purpose for testing, and then put the findings into practice.

Why QA is important

This article explores the reasons why QA is important and outlines some of the key factors that make QA essential to every software project.

The victory of software development depends on quality assurance, known as QA. It checks the finished product for compatibility, functionality, and usability to make sure it lives up to expectations.

Some of the essential points of the importance of QA are:

  • Quality assurance is essential to ensure software products meet the user’s needs and expectations;
  • QA testing can detect errors on, saving time and money in the developing process;
  • A strong QA process can improve customer experience and loyalty by providing a quality product that meets their needs.

What is Quality Assurance?

To identify and correct faults in software systems, you can use quality assurance. Verifying that the software system complies with the customers’ specifications is the aim of quality assurance.

The reliability and maintainability of the software system are also ensured with the aid of software quality assurance.

When quality assurance is a first priority, everyone in a company is focusing on producing outputs that are free of errors. Software testing services entail the implementation of efficient processes that anticipate potential issues and eliminate the need for workarounds.

Companies that value quality assurance urge staff to see every stage of the software development process as a “product” with a “customer” in mind. Consequently, a business analyst gives project managers, designers, and developers information.

A designer builds a product that developers may use to translate wireframes and images into functional code, and so forth.

What does Quality Assurance Mean for Software Testing?

Quality assurance is an important part of software testing. It is a process of ensuring that the software meets the requirements of the customer and is free from any defects. It includes activities such as setting up test plans, developing test cases, executing tests, logging defects and tracking their resolution.

QA involves analyzing the results of the tests and ensuring that the software meets the required standards. It is essential for ensuring that the software is reliable, efficient, and secure.

Quality assurance helps to ensure that the software is working as intended and that you can identify any issues before you release the software.

The Benefits of Quality Assurance

There are many benefits of quality assurance for software testing. It helps to ensure that the software meets the required quality standards and it helps to identify and fix errors that could lead to software failures.

Is a critical part of the software development process and it helps to ensure that the software is fit for purpose and is fit to use.

Quality assurance also helps to improve the existing quality of a product while also helping to minimize customer risks. By identifying and fixing defects in software early on, QA minimizes the risks of those defects being exposed to customers.

Why QA is important?

Quality assurance may assist in locating any possible issues with the product. It can identify a manufacturing process component that can be rapidly rectified. As it draws attention to expensive or inefficient operations, it may also be quite helpful in keeping expenses under control.

Because consumers have favorable experiences with a product, effective QA practices may also improve a brand’s reputation. Supervisors can prioritize resolving production difficulties as soon as possible and making sure no new problems arise.

Time is saved with quality assurance

While developing error-catching systems takes time at the beginning of the process, fixing problems that are permitted to occur or spiral out of control takes even longer. An excellent example is the creation of software.

An investigation revealed that correcting a mistake later, in the requirements design stage, might take up to 150 times longer.

  • Quality assurance testing helps identify errors in the software development process before it goes live, which can help save time and resources in the event of a major issue;
  • Time is also saved as an organization does not have to deal with customers complaints and support requests that would have arisen from a faulty launch;
  • Automated testing tools such as unit tests, integration tests, and end-to-end are essential for catching errors quickly and efficiently, helping to ensure the timely of high products and services.

Quality assurance reduces costs

Some businesses might be reluctant to engage in quality assurance due to the cost, yet doing so really saves money in the long run. It is less expensive to invest in issue prevention than in problem repair.

Since you will waste nothing, quality assurance methods help reduce material costs. For instance, if a company produces a product without having quality assurance procedures in place, that product won’t sell as well or customers may complain about it. The company must then spend more money on producing additional products to replace the inferior ones.

Quality Assurance Helps You Stay Ahead Of Competitors

If you are looking to stay ahead of competitors, you need to ensure that your products meet the highest standards possible. This means that you should perform thorough testing and analysis to ensure that your products are as good as they can be.

You can meet consumer expectations

Customers have high expectations, and negative product experiences might leave an adverse memory. If a customer is unhappy, they may select a different vendor or opt not to make another transaction.

Effective quality assurance systems prevent the social media sharing of defective or subpar products, which may be detrimental to enterprises. If a customer is not pleased with a purchase they could spread the word, which would harm the company’s reputation.

How QA Helps Improve Productivity

Quality assurance helps reduce errors and maximize efficiency by catching mistakes before they reach the customer. This ensures that you deliver the product or service of the highest quality, with all processes and procedures adhering to the established standards.

Quality assurance teams review every step of the production process to identify any potential issues or discrepancies that may arise. They then take the necessary steps to address and resolve the issues to ensure that the product or service meets all the established requirements.

QA is an important tool for any organization, helping to protect its reputation and maintain customer trust.

Quality assurance includes a range of activities such as testing, inspecting, and auditing, which help to identify and resolve any issues that may arise. It helps to ensure that you deliver the product to the customer as expected and is fit for purpose.

Identifying Quality Problems Through QA

Quality assurance processes help to identify problems with a product before you release it. Ensuring the quality of the product is of utmost importance to business, which is why it is so critical for any product life cycle.

It is important to find and fix defects and ensure the product meets all the requirements of the customer.

QA teams should use both manual and automated tests to thoroughly evaluate a product for potential issues.

Manual testing is essential for exploring the usability of a product. You can use automated tests to quickly and accurately assess the system’s performance, stability and security.

Working together, the manual and automated tests can provide valuable insights into the quality of the product and can help identify any problems that you need to address.


Overall, the importance of QA cannot be underestimated. It ensures that products are developed and delivered with consistency, quality, and reliability. Poor QA leads to unreliable products that fail to meet customer expectations.

A good QA strategy can help reduce costs as well as enhance customer satisfaction. Therefore, businesses need to adopt a comprehensive approach to testing, involving both manual and automated testing tools for better results.

bookmark_borderOffshore software testing

Software testing is an essential process in the software development life cycle. It helps ensure that the software meets the required quality standards. However, testing can be a time-consuming and expensive process. This is where offshore software testing comes in.

Offshore software testing is a cost-effective way to get the testing done quickly and efficiently. In this blog post, we will discuss the benefits of offshore software testing and how it can help you save time and money.

Table of Contents

What is offshore software testing?

Offshore software testing is a process of testing software applications that are developed in another country. This type of testing is often used by companies who want to save money on development costs. It can be performed by either hiring a company that specializes in this type of testing or by sending employees to another country to test the software themselves.

Reasons To Use Offshore Software Testing

Software testing needs to be an essential step in the creation of software. But a common misconception is that software engineers can identify and correct any flaws or problems on their own. They must perform the QA process themselves rather than work on the following set of activities.

Developers of software should pay attention to the development tasks. Quality assurance is not their main duty, but they do test their codes. They could also become defensive while assessing their work. The consequences of this frequently go unnoticed.

You should employ QA testers to perform the QA operations if you want to prevent errors and major user and financial losses.

Here are various reasons for using offshore software testing.

Provide software free of bugs

Software bugs can manifest as a UX/UI issue or as fatal mistakes that result in the program crashing. These vulnerabilities may also cause data loss and reduce any user’s efficiency. Fixing these issues has gotten considerably simpler thanks to testing breakthroughs. However, glitches still occasionally appear out of nowhere.

In the creation of software, defects must be kept to a minimum. You will be able to identify errors and correct them quickly if your offshore software company includes highly qualified QA testers. Additionally, you may anticipate end-user actions that could lead to these mistakes. Without QA testing, it’s possible that the program won’t perform as intended, which would be negative for the user experience.

QA testers ensure that the product satisfies all necessary functional and non-functional requirements.

Efficiency in time

Making the most of time zone differences is one method to benefit from offshore testing. You can set the same working hours for an offshore crew as you can for an onshore team while working with them.

You can also design a timetable that allows onshore and offshore teams to work at the same hours. Maximize the nine to thirteen-hour difference. Your offshore staff can pick up where the onshore team left off once they’ve finished working for the day. By doing this, teams can work together continuously, boosting both effectiveness and productivity.

Collaborating with offshore teams also has the advantage of giving you the freedom to react fast to any unforeseen developments that arise during a sprint.

Lower costs

Testing services are usually a pretty expensive line item for a company to incur. Though sticker prices and domestic lab testers may seem cheaper upfront, an offshore firm can cut drastically deeper into that budget while still offering high-quality work.

Overseas firms generally have a higher volume of testers working cases, which cuts down on cost per man-hour. Add to that the cost of office overhead in a developed Western city, and you are looking at a lower overall cost for the same quality of work.

A fresh perspective

Cultural diversity helps you see the software program from fresh angles, improving your understanding of how to manage mistakes. A good QA specialist must offer insightful advice on how to fix product flaws. Without using any personal biases, one must anticipate probable hazards and behavioral effects of the software product.

Working with independent QA testing firms promotes objectivity, which raises the general caliber of your software product.

Your QA testing team needs to be capable of making important judgments. That is made possible by offshore QA teams. You can avoid issues once your software product launches by adhering to this crucial step in software development.

An increase in efficiency overall

Work is more easily managed when done in collaboration with experts in a certain section. With the aid of knowledgeable developers and QA engineers, you increase your trust that your software product will function.

To ensure that all customer requirements are satisfied, the QA team works with the product owner. That increases productivity since you can be sure that once the software is finished, it has undergone a sufficient amount of testing.

You can attract users if you have sufficient time to carry out upgrades. You desire that folks use your offering. Spend your free time coming up with plans or testing ways to improve the software.

In summary, the advantages of offshore QA in software development entail:

  • Deliver functional, bug-free software of the highest caliber
  • Save money and time that would otherwise be wasted on business operations
  • Boost the effectiveness and output of the software team you collaborate with.

Offshore Software Testing’s Drawbacks

Most issues with offshore software testing are communication-related, which is a problem for everyone, no matter where they are in the world. Language, cultural, and technology disparities exacerbate common communication problems and opaque procedures.

Communication difficulty

Language difficulties are the most prominent example of these communication issues. Once engineers and QA employees are involved in routine contacts, it becomes evident that life is difficult dues to an inability to engage in a simple discussion.

Time Zone Variations

Due to the inability to work during the same hours, asynchronous communication methods like email and messaging are needed. Frustrations might arise from waiting for responses and not knowing if your message has been heard, much less understood. It does take dedication and practice, but organized businesses can work around the issue by complementing the asynchronous contacts with regularly scheduled in-person meetings via video conference or onsite visits.

Level of Work

This issue is largely a holdover from the beginnings of offshore software when labor cost savings were prioritized over producing high-quality work. Especially in nations like India that take pride in their software competence, such as times are essentially in the past. However, you run the risk of getting a subpar service when you skimp on screening QA partners.

Do your research and, if at all possible, look for a QA partner that combines domestic account management with a combination of offshore/onsite software testing.

Hidden Charges

The aforementioned communication limitations can cause more than simple annoyances. They might cost you money. It’s possible that unexpected delays brought on by delayed response times or poorly comprehended instructions will increase labor costs. Then there is the additional burden that your production cycle experiences once workflows are backed up.

However, there is always a fix for every issue. Finding the ideal QA partner is crucial for maximizing the potential advantages of offshore testing.

When Do You Automate Testing

One of the most common questions we get asked is when you automate your testing. The answer, unfortunately, is not as straightforward as we would like it to be. It depends on several factors. including the size of your team, the frequency of releases, the type of application you are building, and the level of risk you are willing to accept.

In this blog, we will explore some of these factors and help you determine when you should automate testing.

What is Test Automation?

Test automation is the process of automating the execution of test cases. Test automation can be used to automate functional, regression, and load testing. Automated testing can be performed on web applications, desktop applications, mobile applications, and web services.

Test automation is used to improve the efficiency of the testing process. It helps by reducing the time and effort required to execute manual test cases. It can also be used to improve the accuracy of test results by eliminating human error.

Why is test automation important?

Test automation is essential for software development for several reasons. First, it allows for rapid feedback during the software development process. Without test automation, developers would have to wait for manual testing to be completed. This will affect them because they can’t gauge the effectiveness of their code changes as fast as they should.

Second, test automation can help to improve the quality of your software by catching errors and defects early on. Third, test automation can save time and money in the long run by reducing the need for manual testing. Finally, test automation can help to improve the speed and efficiency of the software development process overall.

When to automate your software testing

There are a few key factors to consider when deciding whether or not to automate your software testing:

The size and complexity of your project

If your project is large and complex, with many different features and functionality, it may be difficult to test manually. Automated testing can help to cover more ground and ensure that all aspects of the projects are tested thoroughly.

The time frame for your project

If you are working on a tight deadline, automating testing can help you speed up the process and get results more quickly. It can also be helpful to automate if you are planning to release regular updates or iterations of your software, as this can help to ensure that new features are properly tested before being released to your users.

The frequency of releases also plays a role in your decision to automate. If you plan to release updates or new features regularly, it makes sense to consider automating the testing of said updates and new features so that you don’t have to manually test them every time.

If you only release your software once in a while, then it might be feasible to test it manually each time.

The type of application you are building

The type of application you are building also affects the decision to automate. If you are building an interactive game, for example, it makes sense to automate testing since there are many different ways for users to interact with the application. If you are building a transactional application, there are likely fewer ways for users to interact with your software, making it easier to test manually.

When the price is reasonable

The basic decision is to reduce costs everywhere you can while still producing a high-quality product. Automation excels in this situation. But because automation tools are expensive, the project size must be substantial enough to cover the expense. Additionally, for the price to make logical sense, the test must last the necessary amount of time.

When you have a lot of tests to run at once

It’s difficult to do the same manual tests at the same time. It is unlikely that a team will be able to execute 100 tests simultaneously. Teams can test quickly without feeling under pressure thanks to automation, which makes this task incredibly quick.

When you need to run tests frequently

If you find yourself running the same tests over and over again, it’s probably a good idea to automate. This will save you time in the long run and allow you to focus on other areas of your software development process. Additionally, if you have a large number of tests to run, or if your tests are particularly complex, automating can help ensure that they are all run correctly and efficiently.

When you are sure the quality will be improved

Automation eliminates the chance of human error. For this reason, using automated testing in specific circumstances can significantly enhance quality. A product that has been thoroughly examined and can be repeatedly tested will be delivered if you can run hundreds of tests at once.

When you need to test different configurations

Geographical location and configuration settings can affect your software development project. If these are likely to change shortly, then it might be a good idea to automate your tests so that you can easily adjust your tests to accommodate these changes.

The test that should be automated

While automation can be used at all stages of the testing procedure, White Box and Unit Testing ought to come first. The tests carried out in White Box testing involve sophisticated scenarios that call for a lot of data or a pre-established environment configuration, while they can also be employed in Black Box testing.

Black Box Testing should be the final phase you automate because it concentrates on the user experience.

What different kinds of testing are automated?

Black Box and White Box Testing are the two main subcategories of software testing. The main distinction between the two is the testing environment. You will employ a different approach depending on the type of test data you want to run.

The main distinction is that Black Box Testing performs the process without being aware of the internal workings of the application. On contrary, the internal structure is understood by the tester in white box testing.

Are you ready to automate?

When choosing tools and frameworks for automating your software testing, consider your technical capabilities and the complexity of your projects. There are a wide variety of tools and platforms available for automating your tests, and most modern programming languages have various frameworks for automation.

Python, Java, C#, and C++ are relatively easy to learn, so they are good choices for projects with simpler automation requirements. Advanced automation frameworks, such as Selenium, are more complex and best suited for more complex automation requirements.

In conclusion, there is no one-size-fits-all answer to this question: “When do you automate testing?”. The decision of when to automate testing depends on several factors specific to each project. However, as a general rule of thumb, it is usually best to automate tests that are repetitive, time-consuming, or likely to be affected by changes in the code.

By automating these kinds of tests, you can save valuable time and resources that can be better spent on other aspects of the project.

How do KPIs work in QA

Quality assurance (QA) is a process or set of processes that help ensure that the products meet customer expectations and requirements. QA is typically associated with software testing but can be applied to any product. In this article, we will discuss how do KPIs work in QA and how to use them to improve your QA process.

Key performance indicators (KIPs) are metrics that are used to track progress and success. In QA, KPIs are used to track the performance of the QA team and the quality of the products they produce.

There are many different KPI s that can be used in QA, but some of the most common include defect density, cycle time, and customer satisfaction.

What is KPI?

KPI, or Key Performance Indicator, is a metric used to evaluate the performance of a process or team. In quality assurance, KPIs can be used to track progress and identify areas for improvement. By setting and tracking KPIs, you can make data-driven decisions to improve your QA process.

There is no hard and fast standard for measuring all of these KPIs, and you can also create KPIs that are not on the list. The following are the most commonly measured KPIs in the software testing industry:

Automated Tests

This KPI compares the percentage of automated test cases to the overall number of test cases. A greater percentage usually indicates a better chance of getting any breaks throughout automation runs.

The percentage of automation threshold should be determined based on the kind of product and the price of automation.

Authored Tests

This KPI can be used to track the number of tests created in a given period. This also aids in comparing test cases to necessities, and the constructed test cases can be analyzed for integration in the regression testing process or ad hoc test suite.

Covered Requirements

This KPI is used to assess the alignment of test cases and demands. A test manager is responsible for ensuring that all requirements have appropriate test cases and for taking action on any requirements that could not be plotted to any test case and vice versa.

The goal is to maintain a 100% mapping of requirements to test cases.

Active Defects

Active Defects are all defects that have not yet been ended. It may contain new, unresolved or untested defects. The testing manager must decide on a threshold value above which instant action should be taken to reduce the number of active defects.

The general rule is that the fewer active defects there are, the higher the quality of the product then.

Defects Fixed Per Day

This is employed to evaluate the efficiency of the development. It is open to interpretation because some bugs may be more difficult to fix than others. This could be used to forecast how much work the testing team will have to do.

Rejected Defects

This KPI compares the percentage of rejected defects to the overall number of defects identified. If the percentage exceeds the threshold value, the underlying problem must be identified and addressed. This could imply more software tester training or improved requirement documentation.

Defects Closure Rate

This KPI is used to assess tester performance in terms of confirming and closing fixed defects. It also aids in better estimating the release cycle.

Reviewed Requirements

This KPI ensures that any criterion that the testing and development team is operating on has been examined and approved by the subject matter expert. Unreviewed requirements may result in inefficient development and testing, which will be expensive in the long run.

Passed Requirements

This KPI is useful when determining the release of a product; if any requirements have not passed testing, the release should just be postponed.

Passed Tests

The number of flaws reported via designed test cases is evaluated to determine the efficiency of the test case design methodology.

Tests Executed

This KPI tracks the complete number of test cases done on a build, both manual and automated, at any particular time.

Test Instances Executed

This KPI is used to determine the velocity of test execution at any given time to ensure that the testing cycle is on the path to the release.

Time schedule and constraint

This KPI is employed to calculate the average amount of time required to run a test. This is useful when offering testing timelines during release planning.

How to use KPIs to improve your QA process

There are a few key ways to use to your advantage:

  1. Set specific, measurable goals for your KPIs: Without specific goals, it will be difficult to gauge whether or not your KPIs are improving your process.
  2. Use data to drive your KPIs: This means constantly collecting data on your process and using it to inform your decisions on which KPIs to focus on.
  3. Be sure to track both qualitative and quantitative data: While numbers are important, they don’t tell the whole story. Be sure to also collect data on things like customer satisfaction, error rates, and repeat incidents.
  4. Monitor your KPIs constantly: Set goals for each cycle or iteration of your product and constantly monitor your KPIs. If you don’t hit your goal, then your need to figure out why and make adjustments.
  5. Be cautious when selecting KPIs to measure quality assurance: Some of them can encourage bad behavior, like measuring the number of defects removed. Instead, focus on indicators that measure the quality assurance process itself, like cycle time or defect density.

Identifying what to measure

There are a few things to consider when trying to improve your QA process with KPIs.

First, you need to identify which aspects of your process need improvement. Once you know what needs to be improved, you can select KPIs that will help you measure progress in those areas.

For example, if you want to improve the speed of your QA process, you could track the time it takes to complete each stage of testing, If you want to improve the accuracy of your QA process, you could track the number of errors that are found during testing.

By tracking those KPIs, you can see how your QA process is improving over time and make adjustments as necessary to continue improving your process.

When are KPIs particularly useful?

  • You have a large testing staff

Having a large testing team also implies that testing tasks will be distributed widely. Monitoring some testing KPIs will be advantageous in ensuring that tasks are dispersed effectively and efficiently.

  • You’ve been working on the same testing procedure for quite some time.

When you have properly implemented a test plan and have executed it several times, it is time to measure the KPIs to determine which areas of your testing process require improvement.

  • You are considering implementing new testing procedures.

If you are considering retooling your testing process, having some KPIs compared to the original procedure will be beneficial. It will assist you in determining what objectives to pursue with the new testing methods.

Creating a process for measuring

Creating a process for measuring KPIs can help improve your QA process in several ways,

First, it can help identify areas of improvement within the process. Second, it can help track progress and identify trends over time. Third, it can help benchmark your process against others.

Finally, it can help ensure that quality standards are being met. By taking the time to measure KPIs, you can improve your QA process and ensure that products are of the highest quality.

In conclusion, KPIs are an important tool for measuring progress and determining whether or not a QA team is meeting its goals. However, it’s important to remember that KPIs should e used as a guide, not as a strict metric. The team should always be striving to improve, regardless of the numbers.
