+# Run all tests headless
+npm run test:e2e
+```
+
+### CI/CD Pipeline
+Tests automatically run on:
+- Every push to main/develop

+- All designers open and functional
+- Buttons are enabled and clickable
+- Forms accept input
+- Monaco editor loads
+- Code generation works
+
+### Code Generation Quality

+
+## Troubleshooting
+
+### If tests fail:
+1. Check if dev server is running
+2. Clear browser cache: `npx playwright cache clean`
+3. Reinstall browsers: `npx playwright install --force`
+4. Run in UI mode to debug: `npm run test:e2e:ui`
+5. Check screenshots in `test-results/`
+
+### Common Issues:
+- **Monaco not loading**: Increase timeout to 15000ms
+- **Selectors not found**: Check if feature toggle is enabled
+- **Timing issues**: Add `waitForTimeout()` after navigation
+
+## Success Criteria
+
+Tests are passing when:
+- ✅ All smoke tests pass (required for every commit)
+- ✅ Full test suite passes on main/develop
+- ✅ No critical console errors
+- ✅ Code generation produces valid files
+- ✅ All major features accessible
+- ✅ Cross-browser compatibility confirmed
+
+## Maintenance
+
+Update tests when:
+- Adding new features
+- Modifying UI structure
+- Changing navigation
+- Adding new designers
+- Updating dependencies
+
+Keep test coverage above 85% for all new features.

+
+## Writing New Tests
+
+### Test Structure Template
+```typescript
+import { test, expect } from '@playwright/test'
+
+test.describe('Feature Name', () => {
+  test.beforeEach(async ({ page }) => {
+    await page.goto('/')
+    await page.waitForLoadState('networkidle')
+    // Navigate to specific tab if needed
+    await page.click('text=TabName')
+    await page.waitForTimeout(1000)
+  })
+
+  test('should do something', async ({ page }) => {
+    // Your test logic
+    await expect(page.locator('selector')).toBeVisible()
+  })
+})
+```
+
+### Best Practices
+
+1. **Always wait for networkidle**: Ensures app is fully loaded
+2. **Use timeout extensions**: Some features need time to load (Monaco, etc.)
+3. **Check visibility before interaction**: Use `.first()` or filter selectors
+4. **Test error states**: Verify no console errors appear
+5. **Test responsive**: Include mobile/tablet viewport tests
+6. **Keep tests independent**: Each test should work in isolation
+7. **Use descriptive test names**: Clearly state what is being tested
+
+## CI/CD Integration
+
+Tests are configured to run in CI with:
+- 2 retries on failure
+- Single worker for consistency
+- Screenshots on failure
+- Trace on first retry
+- HTML report generation
+
+### GitHub Actions Example
+```yaml
+- name: Install Playwright
+  run: npx playwright install --with-deps
+
+- name: Run E2E Tests
+  run: npm run test:e2e
+
+- name: Upload Test Results
+  if: always()
+  uses: actions/upload-artifact@v3
+  with:
+    name: playwright-report
+    path: playwright-report/
+```
+
+## Debugging Failed Tests
+
+### 1. Run in UI mode
+```bash
+npm run test:e2e:ui
+```
+This opens an interactive UI to step through tests.
+
+### 2. Run in headed mode
+```bash
+npm run test:e2e:headed
+```
+Watch tests execute in a real browser.
+
+### 3. Use debug mode
+```bash
+npm run test:e2e:debug
+```
+Pauses execution with Playwright Inspector.
+
+### 4. Check screenshots
+Failed tests automatically capture screenshots in `test-results/`
+
+### 5. View traces
+Traces are captured on first retry: `playwright show-trace trace.zip`
+
+## Common Issues
+
+### Monaco editor not loading
+- Increase timeout to 15000ms
+- Ensure dev server has fully started
+- Check network tab for failed CDN requests
+
+### Feature toggles affecting tests
+- Tests check if elements exist before interacting
+- Use conditional logic: `if (await element.isVisible())`
+
+### Timing issues
+- Add `await page.waitForTimeout(1000)` after navigation
+- Use `waitForLoadState('networkidle')`
+- Increase timeout for slow operations
+
+### Selector not found
+- Use flexible selectors: `page.locator('text=Submit, button:has-text("Submit")').first()`
+- Check if element is in shadow DOM
+- Verify element exists in current viewport
+
+## Performance Benchmarks
+
+Expected test durations:
+- **Smoke tests**: ~30 seconds
+- **Full test suite**: ~5-8 minutes
+- **Single feature test**: ~20-60 seconds
+
+## Coverage Goals
+
+Current: ~85% feature coverage
+Target: 95% feature coverage
+
+Areas needing more coverage:
+- [ ] Lambda designer interactions
+- [ ] Component tree drag-and-drop
+- [ ] AI generation features
+- [ ] Sass styles showcase
+- [ ] CI/CD config generation
+
+## Contributing
+
+When adding new features to CodeForge:
+1. Add corresponding E2E tests
+2. Update this README with new coverage
+3. Run smoke tests before committing
+4. Ensure all tests pass in CI
+
+## Support
+
+For test failures or questions:
+- Check GitHub Issues
+- Review test output and screenshots
+- Run tests locally with debug mode
+- Check Playwright documentation: https://playwright.dev
