Level of Regression Testing in Test Process

Hey folks,

There are 3 types of regression

1) Unit regression: nothing but retesting ie testing to make sure that bug is properly fixed or not / new enhanced feature is working according to the specification.

2)Regional Regression : Unit regression + testing the impact area to make sure that bug fixation or new feature not affecting the unchanged module.90% of the case industry prefers this regression.

3)Full Regression : when it is difficult to identify the impact area after the bug fixation or after adding the new feature ,instead of wasting time in identifying the impact area they will go with full regression.

Hope, this will helpful to you.

Thanks,
