Does this skill help with testing React hooks?

Yes, it provides specific patterns for using renderHook and act to test custom hooks both in isolation and with external dependencies.

How does it handle network requests in tests?

It promotes the use of Mock Service Worker (MSW) to intercept and mock API calls, ensuring tests are deterministic and do not rely on actual backends.

Why focus on behavior instead of implementation?

Testing behavior (what the user sees and does) ensures your tests don't break during internal code refactors, providing much higher confidence and maintainability.

Which testing frameworks does this skill support?

This skill is optimized for Vitest, React Testing Library (RTL), and Jest, which are the industry standards for modern React development.

Can I use this for accessibility testing?

Absolutely. It includes patterns for integrating jest-axe to identify and fix common accessibility violations automatically.
