umbraco-unit-testing

Unit testing Umbraco backoffice extensions built with Lit is facilitated through the @open-wc/testing framework, which supports comprehensive component rendering, context logic validation, and observable state management for isolated frontend customizations.

Mocking the Umbraco context API in component tests is handled through configurable import maps and mocking strategies, allowing you to choose between a full Umbraco environment simulation or a simplified mock-based approach for isolated testing.

Yes, open-wc testing helpers support verifying observable state in Umbraco web components by providing tools to assert Lit element rendering and evaluate context API logic during test execution.

Configuring web-test-runner is required to test Lit elements for Umbraco customizations, utilizing a web-test-runner.config.mjs file to establish import maps and define the testing environment for reliable frontend execution.

Context testing for Umbraco observable patterns works by leveraging configurable import maps to isolate dependencies, ensuring that state management logic and context API behaviors function as expected without requiring a live backend.

A mock-based approach for Umbraco component testing provides faster and more isolated test execution than a full environment simulation, ensuring reliable verification of individual Lit elements and state logic without external interference.
