Overview:

This product analysis focuses on a course material for testing React components using react-testing-library. The course material includes various topics such as rendering React components for testing, using jest-dom for improved assertions, writing more maintainable React tests with dom-testing-library, testing localized content, testing React component state changes, testing prop updates, testing accessibility of rendered React components, mocking HTTP requests with dependency injection or jest.mock, mocking react-transition-group, testing componentDidCatch handler error boundaries, test driving the development of a React form, testing the functionality of a React form, testing react-router provider history object, testing a redux connected React component, testing a custom hook, testing React portals, and testing unmounting a React component.

Features:

• render: Render a React component for testing
• jest-dom: Use jest-dom for improved assertions
• dom-testing-library: Use dom-testing-library to write more maintainable React tests

• http-jest-mock: Mock HTTP requests with jest.mock in React component tests
• mock-component: Mock react-transition-group in React component tests with jest.mock
• error-boundaries: Test componentDidCatch handler error boundaries with react-testing-library
• tdd-markup: Test drive the development of a React form with react-testing-library
• tdd-functionality: TDD the functionality of a React form with react-testing-library
• react-router: Test react-router Provider history object in React component tests with createMemoryHistory
• redux: Test a redux connected React component
• custom-hook: Test a custom hook
• portals: Test React portals
• unmounting: Test unmounting a React component with react-testing-library
