Pls explain the concept of Regression Testing with the help of simple Example
Generally, Regression testing is done on a modified build. Initially we execute the all test cases on the build no.1. when we found any bugs we'll post those bugs to developers. Developer will fix the bugs.and release build no.2. Now, we re-execute the failed testcases along with some other test cases which may got affected by the bug fixing work. These re-executed test cases should be identified properly.
