Playwright Writing

Purpose

Guide the creation of reliable, maintainable Playwright E2E tests that test real user-visible behavior against real application data.

When NOT to Use

• Unit tests (use Jest/Vitest instead)
• Integration tests that don't need browser automation
• API-only testing (use Playwright's API testing or dedicated tools)
• Performance/load testing (use k6, Artillery, etc.)

🚫 FORBIDDEN Patterns (Zero Tolerance)

Never Mock Application Data

Your tests MUST hit your real API endpoints.
