What is the difference between Regression and Retest
Testing?

Answer Posted / mahi

In Retesting one will perform testing on the same functionality again and again with multiple sets of values inorder come to a conclusion whether it is working fine or not.

In Regression testing one will perform testing on already tested functionality again and again.usually we do it in two scenarios,
1.Whenever the tester find some defects,send it to the development department,after rectification developers will release the next build,once the next build is released the testers will check the defect functionality aswellas the related fuctionality are working fine or not.
2.Whenever some new features are added,next build is released to the testing department then the testers will once again test all the related features of the those new features inorder to check whether they are working same as previous or not.

Retesting starts from the first build and cotinue up to last build.
Regression testing starts from second build and continue up to last build.

pls let me know if at all any thing wrong.
