@testing-library/react is a popular testing utility library for React applications. It provides a set of simple and intuitive APIs that allow you to write tests that closely resemble how users interact with your application. The library encourages best practices for testing by focusing on testing the application from the user's perspective.

v3.11.0(about 4 years ago)

This package was last published over a year ago. It may not be actively maintained.Types definitions are provided via a separate npm package: @types/enzymeNumber of direct dependencies: 22Monthly npm downloads

Enzyme is a JavaScript testing utility for React that provides a simple and intuitive API for testing React components. It allows you to simulate rendering, interact with components, and assert on their behavior and output. Enzyme supports different rendering methods like shallow rendering, full rendering, and static rendering, giving you flexibility in testing different aspects of your components.

Both @testing-library/react and Enzyme are popular testing libraries for React applications. However, @testing-library/react has gained significant popularity in recent years due to its focus on testing user behavior and promoting best practices, while Enzyme has been around for longer and has a large user base.

Testing Approach

@testing-library/react follows a more user-centric testing approach, where tests are written from the perspective of the user interacting with the application. It encourages testing the application as a black box and focusing on user behavior. Enzyme, on the other hand, provides a more component-centric testing approach, allowing you to directly manipulate and inspect the internal state of components.

API Design

@testing-library/react provides a simple and intuitive API that encourages writing tests that closely resemble how users interact with the application. It promotes using queries to select elements based on their text content, labels, or accessibility attributes. Enzyme, on the other hand, provides a more extensive API with a wide range of utility methods for interacting with and asserting on components.

Component Rendering

@testing-library/react uses JSDOM or a real browser environment (via tools like Puppeteer) to render components, allowing for more realistic testing scenarios. Enzyme, on the other hand, uses a shallow rendering approach by default, which renders only the tested component without its children. It also provides a mount method for full rendering, but it may be slower and less efficient compared to @testing-library/react.

Community Support

Both libraries have active communities and provide good support. However, @testing-library/react has gained more traction and has become the de facto standard for testing React applications. It has a larger community, extensive documentation, and many resources available online. Enzyme, being an older library, still has a strong community but may have slightly fewer resources and updates compared to @testing-library/react.

Integration with Ecosystem

@testing-library/react integrates well with other testing tools and frameworks in the React ecosystem, such as Jest, Cypress, and React Testing Library. It promotes using a combination of these tools for comprehensive testing. Enzyme, on the other hand, can be used with various testing frameworks but has a closer integration with Jest.
