Does this skill support TypeScript type safety in tests?

Yes, it includes patterns for using vi.mocked() to narrow types and provides guidance on configuring TypeScript declarations for custom matchers.

Can it handle complex mocking scenarios?

Absolutely. It covers function spies, partial module mocking with importOriginal, and the differences between hoisted vi.mock() and dynamic vi.doMock().

Does it provide guidance on testing asynchronous code?

Yes, it emphasizes the importance of awaiting async assertions and using expect.poll for retrying assertions until they pass or timeout.

How does this skill assist with Jest migrations?

It provides a detailed translation table for Jest-to-Vitest APIs and identifies critical behavioral differences, such as how mock hoisting and cleanup functions operate.
