Question

A test engineer generates 70 mutants of a program P and 150 test cases to test the program P. After the first iteration of mutation testing, the tester finds 58dead mutants and 4 equivalent mutants. Calculate the mutation score for this test suite. Is the test suite adequate for program P? Should the test engineer develop additional test cases? Justify your answer.

Answer 1

Answer:

mutation Score = dead mutants / ( total mutants -equivalent mutants ) * 100

Dead mutants = 58

Total number of mutants = 70

Equivalent mutants = 4

So, mutation score = (58 / (70 – 4) * 100) % = 87.87%
