Hi bala,

Regression testing comes under functional testing which is a part of validation. In validation we have unit testing,integration testing which comes under white box testing. after that black box testing. in black box testing we'll do the functional testing.

After enhancing the build like adding some new features to the build we'll do regression testing. in this also we'll check the functionalilty. so it comes under functionality.

Hi guys.

regression testing is a part of system testing.coz once a new build is released we perform regression testing.once regression tests are passed then that build of software is released.

Regression testing performed after each phase relased to ensure taht, is there any impact to previous software.

Re-Testing after changes or modifications and regression testing performed after enhancements also.

Verification is :: Testing if the product is made right. It is static in nature.

                      Methods are:: walkthroughs,Inspections,Buddy checks

Validation is :: Testing if the right product is made.

                    Black Box::

                    white Box

These i am telling after reading book "Testing in real world" Author ::Edward kit .

Both are  combined sa V&V activity in SQA process

Hi All,I am really confused now with the answers posted on this page.This is what I thought about V&V:Verification: To check if something does the correct thing. For e.g. If you give input to a program that adds two integers as follows:300 + 300 and it results in 600. Then u can assume that u verified that it is the right thing.Now the challenge is to validate the program (testing) - i.e. to check if something which is correct does the thing rightly.Now provide a = -300 and b= -300 and if you see 0, it doesnt make sense for you as you will now be aware that the product cannot be VALIDATED, which means it is not VALID.So, testing means validation ONLY and not verification.Verification should be done by development team while validation is black box testing.Please correct me if i am wrong..Regards,Surya
