Regression Testing: Why is It Important?

Regression testing is a type of software testing that verifies that changes to a system or application do not introduce new defects or cause existing functionality to break. It is typically performed after making changes to the codebase, such as adding new features or fixing defects.

The goal of regression testing is to ensure that the changes made to the system have not affected its overall functionality or stability. It helps to ensure that the system is still working correctly and that new changes have not introduced any unintended consequences. Regression testing is typically performed by executing a suite of test cases that exercise the various features and functionality of the system. This can include both manual testing, where a human tester manually performs the tests, and automated testing, where a testing tool or script is used to execute the tests.

Regression testing is an important part of the software development process, as it helps to identify and fix any issues that code changes may have introduced and helps maintain the system’s quality and reliability. Thus, below are some of the benefits of regression testing.

• Maintaining system stability– Regression testing helps to ensure that changes to the system have not caused any unintended consequences or broken existing functionality. This helps to maintain the stability and reliability of the system.
• Identifying defects– Regression testing can help to identify defects that code changes may have introduced. By executing a suite of test cases, it is possible to uncover defects that may not have been identified during initial testing.
• Improving software quality– By performing regression testing after making changes to the codebase, it is possible to improve the overall quality of the software. This is because defects that are identified during regression testing can be fixed before the software is released to users.
• Reducing risk– By identifying and fixing defects before the software is released, regression testing helps to reduce the risk of users encountering defects or issues when using the software.
• Reducing rework– If defects are not identified and fixed until after the software has been released, it may be necessary to perform additional testing and make changes to the codebase. This can be time-consuming and costly. Regression testing helps to avoid this by identifying and fixing defects before the software is released.
• Facilitating continuous integration and delivery– Regression testing is often performed as part of a continuous integration and delivery (CI/CD) pipeline, where code changes are automatically built, tested, and deployed. This allows teams to quickly and efficiently deliver new features and updates to users.
• Improved user experience– By identifying and fixing defects before the software is released, regression testing helps ensure that users have a positive experience. This can lead to increased customer satisfaction and loyalty.
