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. 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.

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.

An overview of how to prepare for a QA interview

A QA interview is an opportunity for a company to assess your skills and knowledge in quality assurance. It is important to be prepared for a QA interview to demonstrate your abilities and stand out from the competition.

Some things to expect in a QA interview include questions about your experience with various testing tools, your approach to quality assurance, and your knowledge of software development processes. It is also common for interviewers to ask about problem-solving skills and how you would handle various testing scenarios.

To prepare for a QA interview, brush up on your knowledge of testing tools and software development processes. You should also be prepared to talk about your experience with quality assurance and your approach to problem-solving.

Research the company

It’s always a good idea to do your research on a company before you interview them. This is especially true for a Quality Assurance interview, as you’ll want to be able to speak to the company’s quality standards and how you would help them meet or exceed those standards.

Here are a few tips on how to research a company for your next QA interview:

  • Google

Google is a great resource for researching companies for a QA interview. Simply enter the company name into the search bar and you will be presented with a wealth of information, including the company’s website, recent news articles, and more.

This is a great way to get an overview of the company and learn more about its products and services. You can use Google to find specific information about the company’s hiring process, such as their interview questions and what to expect.

  • Review the company website

When researching a company for a QA interview, the first place to start is the company website. This will give you an overview of the company’s products and services, as well as its company culture.

  • Look for recent news articles

Another way to research a company is to read news articles about them. This can help you learn about any recent changes or developments at the company.

  • Browse the business’s social media

Checking out the company’s social media will give you a good sense of the company’s culture and values. It will also give you a good sense of their work environment and what they’re like as an employer.

  • Read the company’s reviews

A great way to learn more about a company is to read reviews from current and former employees. This can give you insight into the company culture, work/life balance, and what it’s like to work there overall.

Do a practice run

Doing a practice run for a QA interview can help you feel more prepared and confident going into the real thing. To do a practice run, start by finding a friend or family member who can ask you questions similar to what you might be asked in an interview.

Take your time answering each question, and pay attention to how you feel as you’re doing so. If you feel nervous or unsure of yourself, take a deep breath and relax. Remember that you’re just practicing and that there’s no need to be perfect. After you’ve answered all of the questions, take some time to reflect on how the practice run went.

Once you identified your strengths and weaknesses, work to improve on the things you did wrong while landing a QA job, and keep those lessons in mind going into the real interview.

Know your resume

No matter how much experience you have as a QA tester, it’s always important to be prepared for your next interview. After all, your resume is the first thing that potential employers will see, and it’s important to make sure that it accurately reflects your skills and experience.

To that end, here are two tips on how to prepare your resume for your next QA interview:

  1. Make sure your resume is up to date: Include any new skills or experience you may have gained since the last update.
  2. Highlight your experience with specific QA tools and technologies: Employers want to know what you’re familiar with and how you can use those tools to help them.
  3. Consider including a skills section at the end of your resume: While most QA professionals include this section before their work experience, there is no wrong place for it. Test yourself…did you include all of your relevant skills on your resume? If not, add them in a skills section. This can help the employer quickly identify that you have the right QA skills for the job.
  4. Make your employment history speak for you: While it’s important, to be honest about your work history, you don’t have to include every job you’ve had. Instead, focus on putting together a solid five to 10 years of work history that showcases your strongest attributes.

No matter what technology you use, always be sure to check your software’s documentation and online tutorials to get a sense of how the tool functions and what kinds of tests you can run with it. This insight will help you during your interview.

Testing concepts for your QA interview

To succeed in your QA interview, you will need to have a solid knowledge of several concepts. Those concepts include test design techniques, software development processes, tools, and attributes. Let’s go over some of the most common testing concepts that you will encounter in your QA interview:

  • Formal Testing and Informal Testing

Before we go further, we should define two testing terms: formal testing and informal testing.

Formal testing is the structured method of evaluating a software application by assuming the role of a software user. Informal testing is simply the same thing, but without any predefined requirements or scripts.

  • Test design techniques

You should be able to identify several test design techniques, such as black box testing, white box testing, integration testing, acceptance testing, and component testing.

  • Test objectives

You should also be able to identify the different objectives that tests can have, such as validation, acceptance, design, and equality criteria.

  • Testing strategies

Try and learn to identify several testing strategies, such as mutation testing, boundary-value analysis, design-based testing, and exploratory testing.

  • Tools of the testing trade

Try and familiarize yourself with several tools of the testing trade, such as debuggers, compilers, interpreters, simulators, profiling tools, bug trackers, and URL validators.

  • Test documentation

You should be able to document tests in various ways, such as using a test plan, an inspection report, a test summary, or a test report.

  • Test measurement

Prepare by being able to measure various test properties, such as complexity, completeness, accuracy, validity, stability, maintainability, and minimality.

  • Test optimization

You should be able to optimize the time spent on testing by identifying test-writing techniques that minimize the time spent testing and maximizes the cost savings.

What to anticipate on the interview day

On the day of your QA interview, expect to be asked questions about your experience with testing and quality assurance. Be prepared to discuss your approach to testing and how you would go about identifying and resolving issues. The interviewer will also want to know about your problem-solving skills and your ability to work in a team environment. Be sure to have examples of your work ready to share, as well as any questions you may have about the position or the company.
