# E2E Testing Infrastructure - Phase 0 Complete

**Date:** January 16, 2026
**Status:** ✅ Complete
**Spec Reference:** [docs/plans/current_spec.md](../plans/current_spec.md)

---

## Summary

Phase 0 (Infrastructure Setup) of the Charon E2E Testing Plan has been completed. All critical infrastructure components are in place to support robust, parallel, and CI-integrated Playwright test execution.

---

## Deliverables

### Files Created

| File | Purpose |
|------|---------|
| `.docker/compose/docker-compose.playwright.yml` | Dedicated E2E test environment with Charon app, optional CrowdSec (`--profile security-tests`), and MailHog (`--profile notification-tests`) |
| `tests/fixtures/TestDataManager.ts` | Test data isolation utility with namespaced resources and guaranteed cleanup |
| `tests/fixtures/auth-fixtures.ts` | Per-test user creation fixtures (`adminUser`, `regularUser`, `guestUser`) |
| `tests/fixtures/test-data.ts` | Common test data generators and seed utilities |
| `tests/utils/wait-helpers.ts` | Flaky test prevention: `waitForToast`, `waitForAPIResponse`, `waitForModal`, `waitForLoadingComplete`, etc. |
| `tests/utils/health-check.ts` | Environment health verification utilities |
| `.github/workflows/e2e-tests.yml` | CI/CD workflow with 4-shard parallelization, artifact upload, and PR reporting |

### Infrastructure Capabilities

- **Test Data Isolation:** `TestDataManager` creates namespaced resources per test, preventing parallel execution conflicts
- **Per-Test Authentication:** Unique users created for each test via `auth-fixtures.ts`, eliminating shared-state race conditions
- **Deterministic Waits:** All `page.waitForTimeout()` calls replaced with condition-based wait utilities
- **CI/CD Integration:** Automated E2E tests on every PR with sharded execution (~10 min vs ~40 min)
- **Failure Artifacts:** Traces, logs, and screenshots automatically uploaded on test failure

## Validation Results

| Check | Status |
|-------|--------|
| Docker Compose starts successfully | ✅ Pass |
| Playwright tests execute | ✅ Pass |
| Existing DNS provider tests pass | ✅ Pass |
| CI workflow syntax valid | ✅ Pass |
| Test isolation verified (no FK violations) | ✅ Pass |

**Test Execution:**
```bash
PLAYWRIGHT_BASE_URL=http://100.98.12.109:8080 npx playwright test --project=chromium
# All tests passed
```

## Next Steps: Phase 1 - Foundation Tests

**Target:** Week 3 (January 20-24, 2026)

1. **Core Test Fixtures** - Create `proxy-hosts.ts`, `access-lists.ts`, `certificates.ts`
2. **Authentication Tests** - `tests/core/authentication.spec.ts` (login, logout, session handling)
3. **Dashboard Tests** - `tests/core/dashboard.spec.ts` (summary cards, quick actions)
4. **Navigation Tests** - `tests/core/navigation.spec.ts` (menu, breadcrumbs, deep links)

**Acceptance Criteria:**
- All core fixtures created with JSDoc documentation
- Authentication flows covered (valid/invalid login, logout, session expiry)
- Dashboard loads without errors
- Navigation between all main pages works
- Keyboard navigation fully functional

## Notes

- The `docker-compose.test.yml` file remains gitignored for local/personal configurations
- Use `docker-compose.playwright.yml` for all E2E testing (committed to repo)
- TestDataManager namespace format: `test-{sanitized-test-name}-{timestamp}`
