SKILL.md

Mutation testing assesses test suite quality by introducing small changes (mutations) to source code and verifying that tests fail. If tests don't catch a mutation, it indicates gaps in test coverage or test quality. This technique helps identify weak or ineffective tests.

See also: test-data-generation, continuous-testing, code-metrics-analysis for comprehensive test quality measurement.

Evaluate test suite quality by introducing code mutations and verifying tests catch them. Use for mutation testing, test quality, mutant detection, Stryker, PITest, and test effectiveness analysis. Source: aj-geddes/useful-ai-prompts.
