The mutation-test-runner plugin validates test suite quality by automatically introducing code mutations (arithmetic, logical, and conditional changes) and verifying whether existing tests catch these synthetic bugs. It provides mutation score calculations and survivor analysis to identify gaps in test coverage across frameworks like Stryker, PITest, mutmut, and Mutant.
