Does it support coverage reporting?

Yes, it includes configuration examples for the v8 coverage provider and instructions on how to generate HTML or text-based coverage reports.

Can I use this skill to mock external dependencies?

Absolutely. It includes patterns for module mocking using vi.mock and factory functions to create reusable, typed mock objects for complex dependencies.

How do I run specific tests using this skill?

You can use the command 'nlx vitest run' followed by a file path or use the '-t' flag followed by a test name pattern to execute specific tests.

Does this skill support React component testing?

Yes, it provides guidance for testing React components using the jsdom environment and includes patterns for managing DOM-based assertions.

How does it handle state cleanup between tests?

The skill promotes the use of the afterEach() hook to reset mocks, clear storage, and restore timers, ensuring each test runs in a clean, isolated environment.
