This Skill helps developers ensure React components behave correctly by providing proven patterns and examples for writing fast, reliable unit tests with Vitest and React Testing Library.

Core Features & Use Cases

• Basic Test Structure: Create files named ComponentName.test.tsx and import vitest functions and RTL utilities for consistent testing.
• Test Interactions: Use user-event to simulate clicks, typing, and form submissions.
• Async & Mocking: Handle asynchronous operations and mock APIs to keep tests deterministic and fast.
• Use Case: Validate a Button component renders with the correct label and responds to user input.

Quick Start

Create a test file named Button.test.tsx and run npm test to execute the Vitest suite for your React component.
