[S. No.] 4 In SDLC, actual testing is carried out in this phase. It includes unit testing, integration testing & system testing etc.. Test Execution and bug reporting, manual testing, automation testing is done, defects found are reported. Re-testing and regression testing is also done in this phase. But, I don't agree with this statement. So, if I want to relate the testing phase with STLC, I would say it it is testing of test cases & test plans i.e. is basically review of test cases, test scenarios etc.. [Phase]
