what is mutation testing ? when we are using this type of
testing?

Answer Posted / swetcha

mutations r introduced into a program to test the adequacy
of the test data.A mutation is a SMALL CHANGE made to the
program.The effects of that data should be made up in some
tests.If it doesnot ,the test set is probably inadeqate.
and this type of testing is called mutation
testing...also called as bebugging

The person who is changing the code by adding mutations
should see how the code works.
