Will it automatically install dependencies?

The skill performs a grounding check to verify node_modules and can attempt to install Vitest if it is missing, though it primarily works with your existing package.json configuration.

Does it support code coverage reports?

Yes, it can generate coverage reports using v8 or other providers and output results in various formats including text-summary, HTML, and JSON.

Can this skill handle both TypeScript and JavaScript?

Yes, the Vitest Runner is designed to handle both .ts and .js files, including support for specialized test extensions like .spec and .test.

Does it support parallel test execution?

Yes, it can run tests in parallel using worker threads to significantly speed up the execution of large test suites.

How does it handle failing tests?
