Mutation Testing Strategy
A mutation testing strategy is a planned approach for introducing small, deliberate code changes (mutants) to evaluate how effectively a test suite detects defects. It defines which mutation operators to use, what code areas to target, how to measure mutation coverage, and how to balance accuracy against execution cost. The goal is to identify weak or missing tests that traditional code coverage metrics may overlook.
