- **State Management**: Component communication and persistence
## 🛠️ Writing New Tests
### Test Structure
```typescript
import { test, expect } from '@playwright/test';
test.describe('Component Name', () => {
test.beforeEach(async ({ page }) => {
await page.goto('http://127.0.0.1:8080');
await page.waitForLoadState('networkidle');
});
test('should perform specific action', async ({ page }) => {
// Test implementation
const element = page.locator('selector');
await expect(element).toBeVisible();
// Test interaction
await element.click();
// Verify result
await expect(page.locator('result')).toBeVisible();
});
});
```
### Best Practices
1. **Use Descriptive Test Names**: Clear, action-oriented descriptions
2. **Test User Flows**: Focus on real user interactions
3. **Check Accessibility**: Verify ARIA attributes and keyboard support
4. **Test Responsiveness**: Verify mobile and desktop behavior
5. **Handle Async Operations**: Use proper wait conditions
6. **Clean Up State**: Reset state between tests when needed
### Locator Strategies
```typescript
// Prefer semantic selectors
page.locator('[role="button"]')
page.locator('[aria-label="Close"]')
page.locator('button[type="submit"]')
// Use class-based selectors as fallback
page.locator('[class*="button"]')
page.locator('.form-input')
// Avoid brittle selectors
page.locator('div:nth-child(3)') // ❌ Fragile
page.locator('button:first') // ❌ Fragile
```
## 📈 Continuous Integration
### CI/CD Integration
```yaml
# Example GitHub Actions workflow
- name: Run E2E Tests
run: |
make install-playwright
make test-e2e
env:
CI: true
```
### Test Reports
- **HTML Reports**: Interactive test results
- **JSON Reports**: Machine-readable test data
- **JUnit Reports**: CI/CD integration
- **Screenshots**: Visual failure documentation
- **Videos**: Action replay for debugging
## 🐛 Debugging Tests
### Debug Mode
```bash
# Run tests in debug mode
make test-e2e-debug
# Run specific test in debug
pnpm playwright test --debug accessibility.spec.ts
```
### Common Issues
1. **Timing Issues**: Use `waitForLoadState` and `waitForSelector`
2. **Selector Changes**: Update selectors when components change
3. **Async Operations**: Wait for network idle and animations
4. **Viewport Issues**: Test across different screen sizes
### Debugging Tools
- **Playwright Inspector**: Interactive test debugging
- **Trace Viewer**: Step-by-step test execution
- **Screenshots**: Visual failure analysis
- **Console Logs**: Browser console output
## 🎯 Future Enhancements
### Planned Features
- **Visual Regression Testing**: Automated screenshot comparison
- **Performance Budgets**: Enforce performance thresholds
- **Accessibility Audits**: Automated WCAG compliance checks
- **Cross-Framework Testing**: Extend to other Rust web frameworks
- **Mobile Device Testing**: Real device testing with Appium
### Integration Opportunities
- **Storybook Integration**: Component story testing
- **Design System Testing**: Visual consistency validation
- **API Testing**: Backend integration testing
- **Load Testing**: Performance under stress
