Mutation score is always 100 #19

error

Mujava generates the correct mutants but on executing the mutants, the mutation score is always 100. The same program was executed with a different mutation tool and the same test file, which resulted in a more practical score, thus validating the test file correctness. Attached screenshot shows that although all the test cases pass for a mutant, i.e. the mutant is not killed, the mutation score is always 100 (example- COD_1). The same result was achieved with all the different programs executed with Mujava. Can you state the problem if any, or a way to resolve this issue.
