Validate test effectiveness with mutation testing using Stryker (TypeScript/JavaScript) and mutmut (Python). Find weak tests that pass despite code mutations. Use to improve test quality.
Plugin for mutation testing in TypeScript/JavaScript and Python to identify weak tests by checking if they pass when code is intentionally broken.
Why this plugin
Improves test suite quality by detecting tests that pass despite code mutations, ensuring tests actually validate logic. Integrates Stryker and mutmut tools directly.
Prerequisites
Requires Node.js/Bun for Stryker (TS/JS) or Python for mutmut. Project must have existing test suite.
