What problem does it solve?
Tests for React components and hooks are often ad-hoc, brittle, and hard to scale across projects. This Skill offers a cohesive set of testing patterns to standardize rendering tests, user interactions, async state handling, and API mocking, reducing flakiness and speeding up iteration.
Core Features & Use Cases
- Component rendering tests using Testing Library with accessible queries
- User interaction simulations with userEvent
- Async state testing using waitFor and findBy* helpers
- MSW-based API mocking for deterministic backend behavior
- Hook testing with renderHook
- Accessibility checks with jest-axe
- Clear, maintainable test structure and guidance for teams
Quick Start
Create tests following the Arrange → Act → Assert pattern demonstrated in examples. Start by installing required dev libraries (Testing Library, Vitest, MSW) in your project, then add a new test file next to the component under test and implement tests using the patterns outlined above.
