Mutation testing assesses test suite quality by automatically mutating code and checking for failed tests. It detects code changes that should trigger test failures, uncovering weaknesses in your test coverage to ensure comprehensive validation.

You run mutation testing on your codebase by executing the mutation testing process against your test suite. The framework automatically introduces code mutations and runs your tests to detect which changes slip through, revealing gaps in coverage.

Yes, mutation testing integrates seamlessly with CI/CD pipelines for continuous testing. You can configure it to run on newly merged code, automatically mutating code and checking for failed tests to ensure test suite integrity.

Yes, mutation testing requires an underlying mutation testing framework to execute the process. The framework handles the automatic code mutation and test execution needed to detect changes that lead to failed tests and assess coverage quality.

Your test suite passes despite code changes because of gaps in test coverage. Mutation testing identifies these weaknesses by automatically mutating your code and flagging instances where modified code does not trigger a failed test.

The best way to ensure test suite integrity after merging new code is to run mutation testing within your CI/CD pipeline. This automatically mutates the newly merged code and checks for failed tests to verify comprehensive coverage.
