What problem does it solve?

Writing reliable tests for React components in TypeScript can be verbose and brittle. This guide helps teams apply consistent patterns to verify UI behavior, interactions, and accessibility.

Core Features & Use Cases

• Use jest or vitest with @testing-library/react to render components and query the DOM from a user's perspective.
• Validate user interactions with userEvent and confirm expected outcomes in asynchronous scenarios.
• Ensure accessibility considerations like ARIA roles and semantic HTML are covered in tests.

Quick Start

Create a simple test that renders a component with render and screen and asserts the expected text.
