![]() As a result, the whole process is better documented, which then proves useful both for successful releases and for test automation. Running regression tests repeatedly, often to different results, compels QA engineers to document their testing efforts in every detail. By utilizing the same test suite over and over again, the testing team can deliver results faster and save time for other important tasks. Software regression testing predominantly deals with existing test cases and doesn’t always require writing new ones to test the same product. This helps make sure that the bugs don’t make it into the release-ready version of the product, where they can trigger other issues or disrupt user experience. Timely and regular regression testing allows teams to spot bugs at the early stages of software production. This positively affects the quality of the software product overall and helps create a solid experience for the end users. The main purpose of regression testing is to verify the correct operation and stability of a software product after changes to the code. Here are the biggest benefits of regular regression testing. Regression testing is an integral part of the software development and testing process, and that is why the importance of regression testing is not usually questioned. Why is regression testing important?Īlthough there are currently dozens of testing types known and used in the software QA industry, regression testing has never lost its value or usefulness ever since it became part of the QA routine. ![]() The term regression, in fact, means “a return to a former or less developed state.” The tests are performed to guarantee the new code hasn’t introduced new bugs or triggered any previously undiscovered ones that would cause your software to regress unintentionally. It makes sure that the previously developed and tested software still performs and behaves as intended after undergoing functional or non-functional changes. Software regression testing is in charge of identifying and preventing the aforementioned kinds of software regression. Whether your software is early in development or you’re introducing an update to a released solution, regression testing comes in to ensure that any changes you make to your code do not cause you any pitfalls. This type of regression is the most dangerous: a ticking bomb, unexpected, and thus the hardest to find. Unmasked regressions occur when a change to a piece of code reveals an already existing bug that previously did not affect the software in any way.Remote regressions happen when a change in one part of the code causes an error, or completely breaks functionality, in another part of the software that had no issues before the change.Local regressions take place when a change to a piece of code introduces a new bug and causes a given component to stop working correctly.
