Regression testing is a software testing technique that checks that recent changes or upgrades to a software application do not impair its existing functionality. It involves rerunning previously executed test cases on the modified or updated codebase to identify any unexpected consequences or regressions caused by the modifications. The primary purpose of regression testing is to make sure that the software’s existing functionalities continue to function as expected after new code changes, bug fixes, or enhancements are implemented. This contributes to the software product’s long-term stability, dependability, and quality, providing that it matches the given criteria and provides a consistent user experience throughout subsequent versions.

Regression testing is necessary to ensure that recent modifications to a software application do not mistakenly break current features. Imagine updating your favourite app and discovering that previously working features no longer work as intended. Regression testing helps to avoid such instances by rerunning previously conducted test cases on the updated codebase, detecting any unwanted side effects or regressions early on. This method contributes to the stability and reliability of the program, delivering a consistent user experience across upgrades. Furthermore, regression testing facilitates continuous integration and deployment operations, allowing teams to securely release updates without concern of introducing new bugs.

In simple terms, regression testing is the process of double-checking your work to guarantee that you did not make any mistakes while making modifications to your product. It’s similar to checking a toy after it’s been repaired to make sure it still works properly before returning it to a youngster to play with. This allows developers to identify and correct errors or defects before they become difficult for users. Finally, regression testing helps maintain software running smoothly and makes sure upgrades improve, not disturb, the user experience.
