## Testing Best Practices

### Before Testing

1. Ensure dev server is running: `bun run dev`
2. Check that port 5173 is available
3. Close other applications that might affect performance

### During Testing

1. Monitor system resources
2. Keep network conditions consistent
3. Run tests multiple times for flaky tests
4. Use headed mode for visual debugging

### After Testing

1. Review test report for failures
2. Check performance metrics against baselines
3. Update baselines if optimizations made
4. Commit test results for CI/CD

## Troubleshooting

### Tests Timeout

```bash
# Ensure dev server is running
bun run dev

# Run in debug mode
bun run test:e2e:debug
```

### Performance Tests Fail

- Close other applications
- Run test in isolation
- Check system resources
- Review baseline thresholds

### Flaky Tests

- Run test multiple times
- Use headed mode to observe
- Check for timing issues
- Review async wait conditions

## CI/CD Integration

These tests are designed for CI/CD pipelines:

```yaml
# GitHub Actions example
- run: cd frontend/apps/web && bun run test:e2e
- uses: actions/upload-artifact@v3
  with:
    name: playwright-report
    path: playwright-report/
```

## Version
