Studies show that around 69% of software failures are due to poorly managed updates. This is a common problem for many businesses: after releasing a new update, features that worked fine before may stop working, causing issues in performance and user experience.
The core problem here is that software updates can unintentionally affect existing functionality, causing bugs or system failures. These issues not only frustrate users but also undermine trust in the software and the business behind it.
The solution lies in regression testing in software testing. By conducting thorough regression tests after every update, you can ensure that new changes haven’t impacted the old features. This process helps identify issues early, saving time and preventing costly errors, while ensuring a smooth, seamless experience for users.
Implementing automated regression testing streamlines the process, helping businesses maintain stability while enabling innovation. Let’s see how regression testing helps create a smoother software experience.

What is Regression Testing in Software Testing?
Regression testing in software testing is the process of re-running previously executed test cases after software changes, such as updates or bug fixes, to ensure that existing features continue to work as expected. The goal is to identify any unintended side effects caused by the changes and verify that the new code hasn’t broken or disrupted the existing functionality of the software.
Why Regression Testing is Necessary for Software Development
Regression testing is important in software development to make sure that new updates or fixes don’t cause problems with features that were already working fine. Even small changes to the code can accidentally break something that was stable before.
A real example is Netflix. After an update, some users couldn’t play shows or movies properly. This happened because the update unintentionally broke the playback feature for certain devices.
If regression testing had been done, this issue would have been found before the update was released, preventing frustration for users and protecting the company’s reputation. It shows how regression testing in software testing is essential to keep everything running smoothly after updates.
Steps in Regression Testing
Regression testing in software testing follows simple steps to make sure that updates or changes don’t cause problems with the software’s existing features.
Step 1: Identify the Changes and Impacted Areas
The first step in regression testing is to identify the changes made in the software, whether they are bug fixes, new features, or system updates. Once the changes are identified, it’s crucial to determine which areas of the application may be impacted by these changes.
Step 2: Select the Test Cases
Based on the changes, relevant test cases from the existing test suite are selected. These test cases should cover the impacted areas as well as other critical functionality that might indirectly be affected. If necessary, new test cases are created to address newly introduced features.
Step 3: Prepare the Test Environment
A proper testing environment needs to be set up to replicate the production environment. This includes configuring the system, ensuring that the necessary software versions, databases, and hardware are in place for the tests.
Step 4: Execute the Tests
Once the environment is ready, the selected test cases are executed either manually or automatically. Automated regression testing tools like Selenium, JUnit, or TestComplete are often used to speed up the process and improve consistency by running the same tests across different platforms and browsers.
Step:5 Compare Results and Identify Issues
After executing the tests, the results are compared with the expected outcomes. If any tests fail, the issues are logged, and developers work to resolve the bugs. It’s important to trace failures back to the recent changes to identify their root cause.
Step:6 Re-test After Fixes
Once the identified issues are fixed, the tests are executed again to verify that the fixes are successful and that no new issues have been introduced into the system. This step ensures the quality of both the new code and the existing functionality.
Step:7 Report and Document Results
Finally, a detailed report documenting the tests performed, issues found, fixes implemented, and the overall result is created. This documentation helps track the testing process and provides insights into potential improvements for future updates.
By following these steps, regression testing ensures that software updates do not introduce new bugs and that all existing features continue to function as intended.
Best Tools for Regression Testing in Software Testing
1. Selenium
Selenium is an open-source tool for automating web applications. It supports multiple programming languages like Java, Python, and C#, and works across various browsers. Selenium is highly flexible, widely used for regression testing, and integrates well with CI/CD tools like Jenkins for automated testing in agile development environments.
2. QTP (Unified Functional Testing – UFT)
UFT, formerly QTP, is a commercial tool for functional and regression testing of web, mobile, and enterprise applications. It features a user-friendly interface, keyword-driven testing, and supports integration with other Micro Focus tools, making it ideal for testing large-scale applications in enterprise environments.
3. JUnit
JUnit is a Java-based framework for automated unit and regression testing. It allows developers to write repeatable test cases, ensuring that existing code works after new updates. JUnit integrates seamlessly with CI tools, making it a staple for Java developers who need automated regression testing in continuous integration workflows.
4. TestComplete
TestComplete is an automated regression testing tool for desktop, web, and mobile applications. It supports various scripting languages like JavaScript and Python and includes a record-and-playback feature. TestComplete also integrates with CI tools like Jenkins and Jira, allowing for efficient automation of regression tests and continuous testing in agile development.
5. Katalon Studio
Katalon Studio is an open-source testing platform for web, API, and mobile applications. It supports automated regression testing with features like keyword-driven testing and an intuitive interface. Katalon integrates with CI/CD tools like Jenkins, GitHub, and Jira, making it easy to run regression tests as part of continuous integration pipelines.
In short, choosing the right tool can significantly improve the quality and speed of your regression testing in software testing.
