aFTER SUCCESSFUL EXECUTION OF ALL TEST CASES ON  BUILD MUTATION TESTING IS DONE BY PURPOSELY SEEDING ERRORS TO IT TO CHECK IF TEST CASES CAN FIND THESE ERRORS. IN SHORT, ITS TO CHECK EFFICIENCY OF t.c AND ALSO TO CHECK THE S/W

In mutation testing,developer or programmer intentionally introduce some bugs into the programs and tester has to execute the test cases on that type of build.Here there are two points to be noted,one it will check the test case strength and it will find any other defects,which is unidentified upto that point.

My doubt is by mutation testing,test case strength can be identified,that is correct upto some extent.But ,the bugs that are introduced i.e change in the code,might create other bugs.But if the bug is not introduced than the new bugs might have not arised.What do you say?

a method for determining if a set of test data or test cases is useful, by deliberately introducing various code changes ('bugs') and retesting with the original test data/cases to determine if the 'bugs' are detected. Proper implementation requires large computational resources.

 Mutation testing  means change in program. progammers are performing changes in program to estimate the completeness and correctness of that program testing.mutation testing can decide whether the test coverage is correct or wrong.
