Comprehensive testing workflow for E2E, integration, and unit tests. Use when testing applications layer-by-layer, validating user journeys, or running test suites.
Guide comprehensive testing following the layer-by-layer approach. Test systematically from database → backend → frontend → E2E.
DON'T: Test entire system at once DO: Test each layer independently, bottom-up
Layer 1: Database ✅ → SQL queries
Layer 2: Backend ✅ → API/Edge Functions
Layer 3: Frontend 🟡 → Component testing
Layer 4: E2E 🔴 → Complete user journeys
Test SQL, RLS policies, migrations
Test Edge Functions, APIs
Test components, UI
Test complete user journeys

pnpm tsc && pnpm build && npx playwright test

| Layer | What | Tools | Time |
|---|---|---|---|
| 1. Database | SQL, RLS | Supabase, psql | 2 min |
| 2. Backend | Edge Functions | curl, Supabase CLI | 3 min |
| 3. Frontend | Components | TypeScript, Build | 2 min |
| 4. E2E | User journeys | Playwright | 5 min |
