AI Test Generator

About

The AI Test Generator skill streamlines the entire testing lifecycle by automating the creation of robust unit, integration, and regression tests. It leverages AI to analyze source code and generate high-quality test scaffolds for frameworks like Jest, Vitest, and Mocha, covering happy paths, edge cases, and boundary conditions. Beyond simple generation, it facilitates advanced workflows such as TDD loops, automated coverage reporting, and mutation testing with Stryker to ensure your test suite is actually effective at catching bugs.

Key Features

• AI-powered unit test generation for TypeScript and JavaScript
• Advanced mutation testing to verify test suite quality
• Regression test generation from bug descriptions and git diffs
• 2 GitHub stars
• Multi-runner support including Jest, Vitest, and Mocha
• Automated coverage analysis and gap identification

Use Cases

• Rapidly increasing unit test coverage for complex legacy codebases
• Automating the 'Red' phase of TDD by generating failing tests from feature descriptions
• Verifying test suite reliability by identifying 'survived mutants' in critical business logic
