## Key Features

### 1. Soft Assertions

Tests gracefully handle incomplete features:

```typescript
const button = page.getByRole('button', { name: /create/i });
if (await button.isVisible({ timeout: 2000 }).catch(() => false)) {
  // Test feature if available
} else {
  console.log('Feature not available - skipping');
}
```

### 2. Test Helpers

Reusable functions eliminate code duplication:

```typescript
import { createProject, navigateToProjects } from './critical-path-helpers';

await navigateToProjects(page);
const success = await createProject(page, {
  name: 'My Project',
  description: 'Test',
});
```

### 3. Mock Service Worker (MSW)

All tests use MSW for API mocking:

- No backend server required
- Consistent test data
- Fast execution
- Offline testing capability

### 4. Comprehensive Reporting

Tests generate detailed reports:

- HTML report with screenshots
- JSON report for CI/CD
- Videos of failed tests
- Trace files for debugging

## Next Steps

### To Add More Tests

1. Use `critical-path-helpers.ts` functions
2. Follow patterns in `critical-path.spec.ts`
3. Run in UI mode to debug
4. Verify tests pass locally before committing

### To Update Selectors

1. Run tests in headed mode to see the UI
2. Use Playwright Inspector to find selectors
3. Update helper functions if selectors change
4. Test changes with UI mode

### To Integrate with CI/CD

Add to your workflow:

```yaml
- name: Run Critical Path Tests
  run: bun run test:e2e -- critical-path.spec.ts
  timeout-minutes: 5

- name: Upload Test Report
  if: always()
  uses: actions/upload-artifact@v3
  with:
    name: playwright-report
    path: playwright-report/
```

## Troubleshooting

### Tests Fail Locally But Pass in CI

- Clear MSW cache: `bun run populate:mock`
- Check if dev server is running: `bun run dev`
- Verify Node modules: `bun install`

### Element Not Found

1. Run in UI mode: `bun run test:e2e:ui`
2. Check if element actually exists
3. Use Playwright Inspector to find correct selector
4. Update test selectors

### Slow Tests

1. Check for missing `waitForLoadState('networkidle')`
2. Verify MSW is configured properly
3. Look for unnecessary `waitForTimeout()`
4. Profile with `measurePageLoadTime(page)`

### Test Isolation Issues

- Ensure each test is independent
- Don't share state between tests
- Use `test.beforeEach()` for setup
- Clean up in `test.afterEach()` if needed

## Related Artifacts

### Playwright Reports

- HTML report: `frontend/apps/web/playwright-report/`
- Test results: `frontend/apps/web/test-results/`

### Screenshots/Videos

- Captured automatically on failure
- Located in `test-results/` directory
- Available in HTML report

## Performance Metrics

### Current Performance

- **Single test**: < 2 seconds average
- **Full critical path suite**: ~10 seconds
- **All E2E tests**: ~5 minutes

### Optimization Opportunities

- Consider test parallelization (already enabled)
- Monitor for flaky tests
- Update selectors if UI changes slow tests

## Maintenance Schedule

### Weekly

- Review failed tests
- Check for flaky tests (random failures)
- Update documentation

### Monthly

- Run full E2E suite
- Update selectors if UI changes
- Add tests for new features

### Quarterly

- Review test coverage
- Refactor helper functions
- Performance optimization
