Can I use this for frontend component testing?

Yes, it includes specific strategies for testing UI components using Testing Library alongside Jest or Vitest for React and Vue applications.

How does this help with Test-Driven Development (TDD)?

It provides the structural patterns and boilerplate code needed to write tests before implementation, ensuring code meets requirements from the start.

Which testing frameworks does this skill support?

It primarily focuses on industry leaders Jest and Vitest, including configuration patterns for both Node.js and Vite-native environments.

Does it support mocking external dependencies?

Absolutely. It covers advanced mocking of modules, spying on functions, and using dependency injection to make complex logic testable.
