Regression testing is performed for the 3 scenarios
1. When the defects are fixed
2. when there is the change for request
3. when new features are added

if any modifications or any additions to it plz do it.

Developer fixed the defects and send to tester.Tester test 
the new functionality of the application with the co-
existance of the application.
The new functionality of the application doesn't create any 
problem on the existance application.

Re-Execution of test on the modified build to ensure bug 
fixes work and occurences of side effects

Regression testing is done to check two important aspects.

1.  Whether a previously posted bug is fixed in the new 
build or not.
2.  Whether fixing of bug caused any problems elsewhere in 
the build.

Pls correct if I am wrong.

Hi Ravi,

As much as I know your 2nd point is valid and related to 
Regression Testing. But 1st point defines the process of 
Retesting.

Hence in my point of view- Regression Testing is done to 
ensure that any Bug Fixation, any change or any 
modification made to the software application has not 
brocken any existing functionality.

after develepers release the modified build after tester 
test the application reported bugs are changed or not this 
is called the regression testing
