What is regression testing in software testing used for?

Hi everyone,

what is the purpose of regression testing? I see some projects do this type of testing, some not. Can you please share your experience in this type of testing?
Thanks

    Hi Amit,

    Simply put, regression test is performed when you want to validate new changes in the new build will not break other features or components in system.

    Regression test is often a collection of test cases or test ideas to test the system as a whole. Since this is a big test and repeated test, regression test is normally executed by automation. Of course, you can have your people to run this test manually as long as you find fit.

    >It’s hard to tell because it’s different from project to project, application to application. If you don’t find the need to do regression test, there’s no reason to do that.
