Consider adding: - Interactive testing with Cypress ## ๐Ÿ“ Test Maintenance - Tests are automatically tracked when test files change - Run `npm run test` for unit tests - Run `npm run cypress:run` for interactive tests - View `npm run storybook` for visual tests - Accessibility tests integrated in CI/CD pipeline --- _This testing registry is automatically maintained by git hooks and scripts._ _See `docs/TESTING_DOCUMENTATION.md` for automation details._
