概要
This skill provides Claude with specialized knowledge to implement robust end-to-end (E2E) testing for Umbraco CMS backoffice extensions. By leveraging Playwright alongside @umbraco/playwright-testhelpers and @umbraco/json-models-builders, it enables the creation of reliable test suites that handle complex Umbraco-specific requirements like 'data-mark' attributes, authentication state management, and API-based data setup. It is essential for developers building custom Umbraco packages who need to validate complete user workflows and data persistence against real Umbraco instances.
