When do u perform REGRESSION testing and how to perform
it ?

Answer Posted / gaurav

Regression Testing is nothing but to test the known set of test cases to ensure that nothing has been affected either due to bug fix or addition of any new enhancement. Basically Regression Testing is used to find out the side effect of existing functionality on other functionality.

For eg:-If Functionality B is depending on Functionality A and with the change in Functionality A if the Functionality B is getting affected then all the test cases related to functionality B will be our regression test cases. And If Functionality A & B are interdependent then all the test cases related functionality A & B will be our regression test cases.
