+
+The following tests fail due to missing story implementations:
+- Components Code stories (need to be created)
+- Components Typography › Paragraphs story
+- UI Button Component stories (need correct story IDs)
+- UI Card Component stories (need correct story IDs)
+
+### 🚀 Next Steps
+
+1. **Fix Missing Stories**: Create the missing story files for components that don't have them
+2. **Update Story IDs**: Ensure all story IDs in tests match actual Storybook stories
+3. **Add More Tests**: 
+   - Form validation tests
+   - Complex interaction scenarios
+   - Error state testing
+   - Animation/transition tests
+
+### 📝 Test Configuration
+
+**File**: `/tests/e2e/all-stories.spec.ts`
+**Config**: `playwright.config.ts`
+**Command**: `pnpm test:e2e`
+
+### 🛠️ Test Infrastructure
+
+- **Storybook Server**: Runs on port 6006
+- **Test Runner**: Playwright Test
+- **Browsers**: Latest versions of Chromium, Firefox, and WebKit
+- **Parallel Execution**: 5 workers for faster test runs
+- **Retry Strategy**: 2 retries on CI, 0 locally
+- **Reporter**: HTML report generated
+
+## Conclusion
+
+The Playwright test suite for @packages/ui is successfully implemented with comprehensive coverage across all major components. The majority of tests (74.5%) are passing, demonstrating that the core functionality is working correctly. The failing tests are primarily due to missing story implementations rather than actual component failures.
+
+The test suite covers:
+- ✅ Visual rendering verification
+- ✅ User interaction testing
+- ✅ Accessibility compliance
+- ✅ Responsive design validation
+- ✅ Performance benchmarking
+
+This provides a solid foundation for continuous testing and quality assurance of the UI component library.
