Can it help me mock external API calls?

Absolutely. The skill provides detailed patterns for using vi.mock and vi.fn() to isolate your code from external dependencies and third-party modules.

How does it handle test coverage?

It provides ready-to-use configurations for the V8 coverage provider, including setting specific thresholds for lines, functions, and branches.

Does this skill support the Bun runtime?

Yes, it includes optimized commands and configurations specifically for running Vitest with Bun for maximum performance.

Is it compatible with React or Vue projects?
