Which testing frameworks does this skill support?

This skill provides comprehensive patterns and configurations for Jest and Vitest, the two most popular modern JavaScript testing frameworks.

Can this skill help with mocking API calls?

Yes, it includes specific patterns for mocking global fetch, external modules, and implementing dependency injection for easier API simulation.

Does it cover frontend-specific testing?

While it focuses on core logic, the patterns provided are directly applicable to React, Vue, and other frontend frameworks using Testing Library.

Can I use this for existing projects?

Absolutely. It provides snippets for adding test suites, configuring coverage reports, and refactoring code to be more testable.
