This skill provides a comprehensive framework for writing isolated unit and component tests for Umbraco backoffice extensions. By leveraging @open-wc/testing and Web Test Runner, it enables developers to validate Lit elements, shadow DOM rendering, state management through observables, and complex context logic with rapid feedback. It includes standardized configurations for both full Umbraco integration and high-speed mock-based testing, ensuring that custom backoffice components are robust, maintainable, and verified against real-world browser behaviors.
