Progressive testing is also called as incremental testing. Testing one module after another in an incremental manner, or test one module complete before attaching a new module to it and after adding new module test both modules again as one module is progressive testing.

From verification to validation, testing process progresses towards the release of product.

• However to maintain s/w, bug fixing is required during any stage of development and therefore, there is need to check software again to validate that there has been no adverse effect on already working software.

A system under test is said to be regress it is a modified component fails or

• A new component, when used with unchanged component, causes failure in unchanged component by generating side effect.

Thus it can be said that most test cases begin as progressive test cases but eventually become regression test cases.

Regression testing is not another activity.

It is re execution of some or all of the already developed test cases.
