I agree with Satya to some extend. To my view Regression
Testing is the process of retesting the application after a
defect is fixed, to check if due to this fixed, no other
problems is caused to its related features.
Lets take an example:
In our application, there are 10 features,
Ft1
Ft2
Ft3
Ft4
Ft5
Ft6
Ft7
Ft8
Ft9
Ft10
Lets consider, defects are fixed in Ft4 and Ft8. Now, to
run the regression, we have to check which features are
inter-related to the features Ft4 and Ft8, say Ft3 & Ft5
for Ft4 and Ft7 & Ft9 for Ft8. Once its identified, the
related testcase are identified from Ft3, Ft5, Ft7 and Ft9.
And these related testcases are used for running the
Regression.
Regression Testing run whenever changes are made in the
Application.
