How to how many levels of regression testing is available in our testing process?

Submitted by: Administrator

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 Regressin : 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.
