Summary
Covers the full testing lifecycle for JavaScript and TypeScript projects, from writing unit tests with the AAA pattern to integration and E2E tests with Playwright. The systematic bug analysis framework is solid, walking you through reproduction, isolation, root cause, fix, and validation. It includes practical examples for catching race conditions, SQL injection, XSS vulnerabilities, and performance issues with parameterized tests. Ships with a Python script that scans your codebase to find untested files and prioritizes them by type. Good if you need structured testing methodology rather than just framework documentation, especially the security and edge case checklists that are easy to forget.
