Does this skill help with Redux or Context API testing?

Yes, it includes specific guides for using the wrapper option in the render function to provide necessary context or store providers to components during testing.

How does this skill handle React Hooks?

It provides standardized patterns for using the renderHook API, managing the result.current object, and correctly using act() when testing hook updates.

Why does this skill discourage testing component state?

Following RTL philosophy, this skill promotes testing what the user sees and interacts with. Testing internal state is considered implementation testing, which makes tests brittle and prone to breaking during refactors.

Does this skill support end-to-end (E2E) testing?

No, this skill is focused specifically on unit and integration testing using React Testing Library. It does not cover E2E frameworks like Cypress or Playwright.

보안 및 테스팅

Implements best practices for testing React components, hooks, and context using React Testing Library while avoiding common anti-patterns.

소개

This skill equips Claude with specialized knowledge for unit and integration testing in React environments using modern React Testing Library (RTL) patterns. It enforces a behavior-driven testing philosophy, focusing on user-centric outcomes rather than implementation details. Whether you are testing complex custom hooks with renderHook, managing multi-provider contexts, or handling intricate form validations, this skill ensures your test suite is resilient, maintainable, and free from problematic patterns like shallow rendering or manual state manipulation.
