Regression testing should be performed after any change is made to the code base. Additionally, regression tests should also be executed anytime a previously discovered issue has been marked as fixed and must be verified. This is one of the methods for Regression Testing, specifically employing a regression testing suite, in which all the tests in the existing test bucket or suite should be re-executed. In order to do Regression Testing process, we need to first debug the code to identify the bugs. The main aim of regression testing is that no existing functionality is impacted due to any latest changes.

In this case, manual execution of test cases increases the time as well as cost of test execution. However, if you still want to know more about it or wish to conduct regression testing for your products, then connect with us today. We would be happy to guide you through the testing process with our expertise and make your development journey seamless. Organizations could have avoided these fatalities by conducting regression testing before updating or adding a new feature. From the above example, you must have realized the importance of regression testing in software testing in today’s times.

Understanding Regression Tests

It eases the lives of devs and testers in their agile software development lifecycle and yields maximum output. However, as your application becomes more complicated, the number of test cases will expand. As a result, you need a cloud-based testing infrastructure that can scale as your testing requirements grow.

what is regression-averse testing

For a product we worked on, an iOS image processing app, manual regression testing helped detect several bugs hampering the app UX. The app failed to render images correctly and crashed when the user changed screen orientation. Costly and time-consuming, regression testing is a nagging pain point for the whole delivery team. Luckily, it is possible to make regression testing less painful and more efficient.

How to develop a dependable regression testing strategy

Learn when and how to perform each one, and some tips to get the most out of your effort. Stackify’s APM tools are used by thousands of .NET, Java, PHP, Node.js, Python, & Ruby developers all over the world. Based on the level of development and product stability, a suitable approach for test plan creation can be deployed.

This includes identifying and evaluating risks regarding the quality of the products. When you perform test designing, test implementation, and test execution, you mitigate the risks by following the test plan. While Product A is undergoing regression averse development, a few of these customers help the organization to identify the defects. The testing team is involved in this risk identification phase because it can leverage its experience in defect identification and quality risk analysis.


Once the developer fixes the bugs in the second build in module B, it is sent to the test engineer again. Software products are dynamic; with every added functionality, test cases keep increasing, leading to confusion. This testing type selects specific test cases from a group to evaluate the affected parts of the code. The latest changes introduced to the system may have had an unexpected impact on another part of the system because they have interconnected components. So, when we’ve changed a part of it, it might have certain impact on other parts. Starting the document with the right date, approver name, comment, and summary of the reviewed modifications should be followed.

The tool allows you to set up tests by using reusable code modules and share object repositories that multiple tests or application components can access. The tool provides data and key-driven testing approaches and can be integrated with other tools such as Git, Jira, and Jenkins for improved performance and advanced testing insights. On adding new functionality, regression testing again becomes essential. Here, a few hundred (say 100) test cases are run to verify the working of newly-added features. Let’s consider a simple example of a software company that develops video conferencing platforms. The company must ensure that the first version of the software platform or product includes the basic core features.


Moreover, the rapid regression testing process allows product development to receive informative feedback, which can be responded to immediately and allows instant modification of the software code. Indeed, when it comes to automated regression-testing tools, sometimes it almost seems too easy. The evident exception is the GUIs regression testing, which normally must be executed manually. Sometimes a change impact analysis is performed to determine an appropriate subset of tests (non-regression analysis[4]).

Categorization of test cases enables new testers to quickly grasp the testing approach and offer robust support in accelerating the test execution process. Prioritizing test cases also allows teams to make the process simpler and easier to execute, thereby streamlining the testing process and outcomes. In the case of both the above testing techniques, the observation is that the time interval assigned to the testing process is completed before the entire testing is done. After completing the risk analysis, the team performs tasks such as test design, test implementation, and test execution. In this context, the term ‘quality’ encompasses the features and the demeanor that can affect the satisfaction of the end users, customers, and relevant stakeholders. The QA team determines the defects before product release and the solutions to address them.

  • The tool is supported on various devices such as macOS, Linux, and Windows.
  • This regression test is performed to find problems when a newly written code is inserted in existing lines of code.
  • In Agile, the Kanban dashboard helps select test cases for iteration regression and critical points for full regression.
  • Before starting the regression testing process, it’s essential to know its scope.
  • Categorizing the test cases on the basis of high, medium, and low priorities.
  • The second use is that this graph renders 100% coverage of the test’s basic functionality.

Moreover, the tool also has a large customer base, giving users access to a vast software test automation market community. According to a March 2020 report by Gartner Peer Insights, this tool was recognized as the popular customer choice for software test automation tools. The tool is supported on various devices such as macOS, Linux, and Windows. Moreover, it provides testing functionalities to desktop, mobile, and web applications and support for specific APIs.

Regression testing approaches

Here, you gather all the test cases and prioritize them, i.e., high, medium, and low. Based on this evaluation, you will execute the high-priority test cases first, followed by medium and low priority test cases. The priority will depend on the product’s functionality and user involvement. In this step, based on the results of exploratory testing, the QA team can decide the test cases that they can automate. Automated test cases are faster than manual testing and allow you to re-use the same script repeatedly. So, divide the test cases into two groups – (i) manual test cases and (ii) automated test cases.
