Hi Leena,
Non Regression Testing term came into picture after Regression Testing
Non Regression Testing : After changing some functionality in the application,
we'll go for regression to verify the bugs and its impact on the other functionality of the application.
Example : If release of the project is expected soon, we don't get asmuch time to test the whole application again. At that time thedecision may be taken by tester with lead that dont go for regressioni.e. Non Regression Testing.
In such a case only we have to retest the changing functionality/module/build
I think You know the defination of regression testing.
