What are the libraries/tools required to perform React testing?

Hey Ana,

There are a lot of libraries and tools available to perform testing on React. Some of them are:

  • Enzyme: This is a JavaScript Testing utility for React that makes it easier to assert, manipulate, and traverse your React Component’s output. It is maintained by AirBnB.

  • Jest: This is used by Facebook to test all of its JavaScript code. Jest uses what it calls Snapshot Testing to generate a text file that will act as a reference point for future tests. When the test is run again, Jest will compare the rendered output with the previous snapshot. If there are no changes in the output, then your tests will pass. Jest comes with integrated code coverage reports.

  • Mocha: Mocha is a feature-rich JavaScript test framework running on Node.js and in the browser, making asynchronous testing simple and fun. Mocha tests run serially, allowing for flexible and accurate reporting while mapping uncaught exceptions to the correct test cases. Hosted on GitHub.

  • React Test Renderer: This package provides an experimental React renderer that can be used to render React components to pure JavaScript objects, without depending on the DOM or a native mobile environment.

Hey Ana,

Here are some of the most popular and highly convenient tools that you can use for your react testing project:

React Testing Library: It is one of the most widely-used testing frameworks for React applications. Supported by the open-source community, it allows developers to test components to easily simulate a user’s behavior.

Jest: One of the most widely used tools that come from Facebook, the Jest framework can help cut off all the dependencies.

Mocha: A JavaScript framework that boasts browser support, async testing, and use of assertion libraries giving you complete control.

Jasmine: A behavior-driven-development framework that can be used with third-party tools like Enzyme.

I hope these names will help you with your goals.
