Q. Explain about Mutation testing?
Mutation testing In mutation testing the software is initial tested by using an preliminary test suite built up from the different white box testing strategies. Subsequent to the initial testing is complete mutation testing is taken up. The inspiration behind mutation testing is to make only some arbitrary changes to a program at a time. Every time the program is changed it is described as a mutated program as well as the change effected is called as a mutant. A mutated program is tested alongside the full test suite of the program. If there subsists at smallest amount one test case in the test suite for that a mutant gives a wrong result subsequent to that the mutant is said to be dead. If a mutant remains alive even subsequent to all the test cases have been exhausted the test data is improved to kill the mutant. A main demerit of the mutation-based testing approach is that it is computationally extremely expensive since a large number of possible mutants are able to be generated.
