Regression Testing Tools

Top 11 Regression Testing Tools

A buggy application with various features can negatively affect the user base and cost you money. Software development practices require test automation. Likewise, it is equally important to automate regression testing to analyze whether the app is performing as expected after any feature change or significant upgrade before its final release.

Sometimes changes in code or deployment of a new version of an app surprisingly affect the untouched functionality and fixing bugs can cause new bugs. So, it’s important for developers and testers to always keep in mind that even small, apparently unimportant alterations in the application’s source code can impact the general functionality in unexpected ways. To take precautions against it, QA engineers run regression tests.

In this article, we are going to learn about top regression testing tools. But before we proceed ahead it is important to understand what regression testing exactly means, when it is needed and what factors to keep in mind when choosing the right tool.

Regression testing

Regression testing is done for all functional and non-functional tests to ensure that any new build or modification in the code or bug fixes does not impact the previously working functionality of the existing feature of an application and also has not introduced any new bugs.

Regression means re-executing the unchanged part of the application to verify the impact of the change in the original functionality. In short, running regression tests means ensuring that not only the modification behaves as expected but also checking that it has not adversely affected other existing functionalities that have worked correctly when tested previously

In regression testing generally, test cases are required to be executed again and again. When running regression tests manually testers need to open the application in a browser and perform a set of necessary actions that cover the unchanged parts of an application. This is to ensure that everything works properly and looks perfect..

When the applications grow in complexity, checking the entire application for potential errors repeatedly is tedious, time-taking, costly, and challenging to scale. This also increases the tester’s and programming team’s stress levels because waiting longer to complete testing with each release cycle bothers them.

Hence to reduce their worry and make their task relatively easy various automated testing programs have been introduced that are specialized in regression tests. They provide testing parameters to check new changes in code against previous applications baselines, highlight inconsistencies in testing logs and specify areas where and why an unexpected function broke.

Automated regression test suites help the team to scale up their testing without adding more headcount because by automating regression test suites they can complete tests in a shorter amount of time and run multiple tests simultaneously.

Why the Regression Test

Regression testing is like a verification method when done correctly strengthens the team’s confidence that their application works properly after a code change. It is initiated when a programmer adds a new code to the application or fixes any bug. This testing is a measure to check that the existing functionality is not affected by the improvement in code.

A regression test is crucial in finding bugs during continuous improvement or changes added to the application. It is also required to verify that the new functionality has not negatively affected the existing tested code. If this testing is not performed properly then the application might get critical issues which can put the user into trouble in the live environment.

Hence performing regression testing is vital and plays a significant role in testing. However, to get the most out of this testing, choosing the correct tool is a must. Below are some factors you can consider while selecting the tool.

Factors for choosing a right tool

When you select a tool for regression testing keep the following factors in mind to make a good choice.

  • Select a tool that can easily create and maintain test cases. Also, the structure of test cases and test suites should be easily understandable.
  • The tool should be able to find the loophole that may exist during the requirement cycle.
  • The tool should support seamless integration for CI/CD pipelines
  • The tool must support test case execution depending on the type of application

Automated Regression Testing Tools

Automated Regression Test reduces most of the testing efforts and saves a lot of time. So automating the available set of test cases is an efficient regression test method.

There are many popular regression testing tools available in the market that can do wonders for your regression tests.

Properly executed regression tests help an organization stay competitive in an environment where processes are constantly changing. Automated tools enable the tester to quickly and smoothly execute the regression test case and save huge time. Here we are going to discuss some of the top tools that you can consider using depending on your need. We will start with LambdaTest.


Regression test suites grow with each added new functionality to the application that needs to be updated every time changes are made. Over time, the test suites become so large that executing them manually within tight deadlines seems no longer possible. Since it is repeatable and recurring in nature, it is best suited to automate the regression tests to speed up the process. If executed properly, automated regression testing promises to maximize the test result, provide a good user experience and make developer’s and QA’s life much easier.
