🚀 How to use

Trigger: /click

Trigger by asking to 'generate tests', 'write unit tests', 'analyze test coverage', 'scaffold E2E tests', 'set up Playwright', 'configure Jest', or 'improve test quality'. Provide the source directory or coverage report path. Example prompts:

Generate unit tests for src/components/
Analyze coverage from coverage/coverage-final.json with threshold 80

📄 Output: Test files, coverage analysis reports, Playwright test files, and configuration snippets.

⚠️ Good to know

Requires Python to run the scripts and assumes a React/Next.js project structure.

❓ FAQ

What does the test suite generator do?

It scans React components and generates Jest + React Testing Library test stubs with describe blocks, render tests, and interaction tests.

How do I enforce a coverage threshold?

Use the coverage analyzer with the --threshold flag and --strict to exit with an error if below the threshold.

Can I generate E2E tests for specific routes?

Yes, use the e2e_test_scaffolder.py with the --routes flag to specify routes like '/login,/dashboard'.
