test-coverage

To coordinate Playwright E2E and Vitest unit tests for full coverage, use this skill to surface untested files, map UI components to routes, and generate test templates with fixture-based cleanup.

Track untested files and coverage gaps by running the test-coverage scaffold, which detects new files lacking tests and maps UI components to API interactions to expose unvalidated critical paths.

Yes, you can enforce multi-viewport testing and post-action database validation with Playwright by using this skill to configure test templates that automatically verify authentication and database state.

Yes, you need Playwright and Vitest installed to use the test-coverage skill, as it requires both tooling frameworks to generate E2E and unit test templates and execute fixture-based cleanup patterns.

Prevent orphaned test data when running E2E and unit tests by using the skill's fixture-based cleanup patterns, which automatically remove test artifacts generated during component and API validation.

The best way to map UI components to routes and API interactions for testing is using this skill to analyze your codebase structure and generate coordinated E2E and unit test templates covering those paths.
