## Testing Strategy

### Run All Tests
```bash
# Run all phases
npx playwright test e2e/v2/

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

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

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

---

## Deployment Workflow

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

# 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
```

---

## Feature Flags

```ruby
# config/features.yml
maps_v2:
  enabled: true
  phases:
    phase_1: true  # MVP
    phase_2: true  # Routes
    phase_3: false # Mobile (not deployed)
    phase_4: false

## Next Steps

1. **Review PHASES_OVERVIEW.md** - Understand the incremental approach
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

**Ready to expand Phase 3?** Just ask: "expand phase 3"
