Description
react-testing is an agent skill from the ECC collection by affaan-m, listed on skills.sh. It sets out testing patterns for React components, custom hooks and pages, built on React Testing Library with Vitest or Jest. Its core principle is to test what the user sees and does, rather than implementation details. It covers mocking network requests with MSW, asserting accessibility with axe, and deciding which tests belong in React Testing Library, in Playwright component testing, or in full end-to-end tests. It also covers adding coverage to legacy untested components, migrating from Enzyme or class-era patterns, and setting up Vitest or Jest for a new React project. The skill applies when writing tests for components, hooks or pages, mocking HTTP calls, or checking for accessibility violations. A skill is a SKILL.md file of instructions that an AI agent loads when a task calls for it. It is free and open source, and the skills.sh listing shows all three security audits passing.…
