What testing frameworks does this skill support?

The skill provides comprehensive support for both Jest and Vitest, including configuration files, environment setup, and specific implementation patterns for each.

Can this skill help with mocking third-party libraries?

Yes, it includes specialized patterns for mocking modules like Nodemailer, spying on function calls, and mocking global interfaces like the Fetch API.

Does it support testing for both Node.js and frontend projects?

Absolutely. It covers backend service testing, async API calls, and provides patterns that work seamlessly with frontend testing libraries like Testing Library.

How does it handle code coverage requirements?

The skill includes predefined configurations for collectCoverageFrom and coverageThresholds to help you maintain strict 80%+ coverage standards across your codebase.
