SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill eliminates brittle, implementation-heavy tests that break during refactors, ensuring your test suite validates actual user-visible behavior and accessibility rather than internal component state.

Core Features & Use Cases

  • Behavior-First Testing: Enforces testing via user-centric queries (getByRole, getByLabelText) to guarantee accessibility.
  • Hermetic Network Mocking: Uses MSW to intercept network requests at the boundary, ensuring components run real logic against contract-aligned responses.
  • TDD Workflow: Integrates with tdd-gate hooks to ensure tests are written before implementation, realizing UI acceptance criteria reliably.

Quick Start

Use the react-component-testing skill to generate a behavior-driven test file for the new user profile component that asserts accessibility and handles loading states.

FAQPage Schema
How do I test React components for accessibility using Vitest?▼

React component testing for accessibility with Vitest enforces user-centric queries like getByRole and getByLabelText, validating actual user-visible behavior rather than internal state. This ensures components meet accessibility standards throughout development.

What's the best way to mock network requests in React component tests?▼

Mock network requests in React tests using MSW to intercept requests at the boundary. This hermetic mocking ensures components run real logic against contract-aligned responses, preventing external dependencies from causing test flakiness.

Can I use MSW with React Testing Library for hermetic component testing?▼

MSW works with React Testing Library to provide hermetic network mocking for component tests. It intercepts network requests at the boundary, allowing components to execute real logic against contract-aligned responses without external network dependencies.

Why do my React component tests break during refactoring?▼

React component tests break during refactoring when they rely on implementation-heavy assertions rather than user-visible behavior. Behavior-first testing with accessibility queries ensures tests validate component interactions, making them resilient to internal structural changes.

Does Vitest support TDD workflows for React UI components?▼

Vitest supports TDD workflows for React UI components by integrating with tdd-gate hooks to ensure tests are written before implementation. This realizes UI acceptance criteria reliably through behavior-driven test development cycles.
