Mutation Testing
Mutation analysis induces faults into the software by creating many versions of the software, each containing one fault. Test cases are used to execute these faulty programs with the goal of distinguishing the faulty programs from the original programs. Faulty programs are the mutants of the original, and a mutant is killed by distinguishing the output of the mutant from that of the original program. A test set that kills all the mutants is said to be adequate relative to the mutants. Mutation testing is a way to measure the quality of the test cases and the actual testing of the software is a side effect.

Mutation Testing
Efficient Mutation Testing by Checking Invariant Violations - Mutation testing measures the adequacy of a test suite by seeding artificial defects (mutations) into a program. If a mutation is not detected by the test suite, this usually means that the test suite is not adequate...
