@types/testing-library__react

What is @types/testing-library__react?

@types/testing-library__react provides TypeScript definitions for the React Testing Library, which is a popular library for testing React components. It allows developers to write tests that simulate user interactions and verify the behavior of their components in a way that closely resembles how they are used in the real world.

What are @types/testing-library__react's main functionalities?

Rendering Components

This feature allows you to render a React component and query the rendered output. In this example, `render` is used to render `MyComponent`, and `getByText` is used to find an element with the text 'Hello, World!'.

const { getByText } = render(<MyComponent />);
const element = getByText('Hello, World!');

Simulating User Events

This feature allows you to simulate user events such as clicks, typing, and form submissions. In this example, `fireEvent.change` is used to simulate a user typing into an input field.

const { getByLabelText } = render(<MyForm />);
const input = getByLabelText('Username');
fireEvent.change(input, { target: { value: 'new value' } });

Asserting on Component Output

This feature allows you to make assertions on the output of your components. In this example, `expect` is used to assert that an element with a specific test ID contains the expected text.

const { getByTestId } = render(<MyComponent />);
const element = getByTestId('custom-element');
expect(element).toHaveTextContent('Expected Text');

Other packages similar to @types/testing-library__react

@types/enzyme

@types/enzyme provides TypeScript definitions for Enzyme, a testing utility for React that makes it easier to assert, manipulate, and traverse your React components' output. Unlike React Testing Library, Enzyme allows for shallow rendering, which can be useful for unit testing individual components in isolation.

@types/jest

@types/jest provides TypeScript definitions for Jest, a popular JavaScript testing framework. While Jest itself is not specifically for React, it is often used in conjunction with React Testing Library or Enzyme to write and run tests for React applications.

@types/cypress

@types/cypress provides TypeScript definitions for Cypress, an end-to-end testing framework. Cypress is used for testing the entire application in a real browser environment, which can complement the component-level testing provided by React Testing Library.

@testing-library/react provides its own type definitions, so you don't need @types/testing-library__react installed!
