Testing Strategy

Run All Tests

# Run all phases
npx playwright test e2e/v2/

# Run specific phase
npx playwright test e2e/v2/phase-X-*.spec.js

# Run up to phase N (regression)
npx playwright test e2e/v2/phase-[1-N]-*.spec.js

Regression Testing

After implementing Phase N, always run tests for Phases 1 through N-1 to ensure no regressions.

---

Deployment Workflow

# 1. Implement phase
# 2. Write E2E tests
# 3. Run all tests (current + previous)
npx playwright test e2e/v2/phase-[1-N]-*.spec.js

# 4. Commit
git checkout -b maps-v2-phase-N
git commit -m "feat: Maps V2 Phase N - [description]"

# 5. Deploy to staging
git push origin maps-v2-phase-N

# 6. Manual QA
# 7. Deploy to production (if approved)
git checkout main
git merge maps-v2-phase-N
git push origin main

2. Review PHASE_1_MVP.md - First deployable version
3. Review PHASE_2_ROUTES.md - Add routes + navigation
4. Ask to expand any Phase 3-8 - I'll create full implementation guides
