Regression Testing is nothing but testing the application after the bug is fixed


Firstly when a tester encounters a bug he will send a bug report to the developer, then the developer verifies the bug and fix the bug them. After bug fixing is done tester will take the NEW build, which the developer has send him and testes the build where he encountered the bug previously.

Regression testing is re-execution of some subset of test cases that have already been conducted to ensure that changes have not propagated any unintended funcationality. Regression test pack contains following class of test cases -

 1. representative test cases that will exercise all major functions of system under test.

2. sample tests that exercises the software functions that are likely to be affected by change.

3. tests that exercises the software functionality that have been changed.

According to biology, "regression" is reversion to an earlier or less advanced state or form or to a common or general type. And general meaning of regression is the act of going back to a previous place or state; return or reversion............now when we talk about it for testing it is again going to revision the back state for confirmation that its still adaptive or as per expectation.No matter when we are doing the regression testing but the meaning is same.

S Srinivasulu saying some right,Regression testing is done in 3 situations..

1 After fixing the bug n

2.New ( funcnality is added) change request will come from client

 In these situation testers r conducting  Regression testing to "ensure that any existing funcnalities r distrubed".

Here the thing is:-Whenever a object is incorporated means that particular object should not give any adverse effect to sorrounding functionality....

This process should be defined step by step
1.tester test the application and raise the defect
2.developer agree s the defect and change the code ( i.e noting but a bugfix)
3.after this stage the same application come s to tester side to test that one again is their any new defects are ariseing for this code change this noting but a regression testing

Testing the application with all the test cases to check whether there is any effect on other components of the application due to the modification of the code.

We should do regression testing only after resolvung all the issues.
