Most Useful Testing Frameworks for React JS: Comparing the most popular ones
You might have a preferred tool or framework for testing your React application if you’re a frontend developer working with the React library. To test the components of a React application, many developers utilize Jest, Enzyme, or other popular tools and frameworks. However, not everyone will benefit from the same tool or framework. In the open-source environment, there are numerous testing frameworks and tools for testing React applications.
Choosing the correct tooling and framework for testing, whether you’re doing unit testing, integration testing, or end-to-end testing, is critical to using TDD in React. Let’s speak about several popular React testing frameworks and libraries that many people use daily in this article.
Enzyme is a toolkit that aims to make it easier for React JS Developers to test React components. The Enzyme platform from Airbnb is one of the most popular and very well libraries. To test the React application, developers mix it with different frameworks like Jest, Chai, or Mocha. Only render components, access objects, find elements, interact with elements, and simulate events are done using the enzyme. To make the assertions for it, you can use Chai or Jest. By abstracting the rendering of components, you can test the outputs of React components. Enzyme with Jest has more information on testing the React application.
- Cypress OI
Cypress is a lightweight edge testing framework that allows you to create tests without the need for software installation. You may run tests on a real web page or from the command prompt with it. In addition to testing your code on a real web page, you can use search engine development tools simultaneously. The framework includes a control panel that allows you to monitor the progress of your experiments.
- React Testing Library
Kent C. Dodds produced React-testing-library, which is supported by a large developer community. It enables you to quickly test the component and replicates user behavior during your tests. This package, like enzyme, is a complete set of React DOM testing utilities aimed at simulating real-world user activities and workflows.
This library has some restrictions, such as the inability to perform shallow rendering and the inability to access the internal business of your components, such as states.
Although Puppeteer does not yet allow a significant variety of extensions, the future seems bright.
The Most Popular Ones!
Jest and Enzyme
Jest and Enzyme are the most popularly used testing frameworks for React JS Development Let us see how are they similar and different so that developers could choose the most relevant framework!
How are they similar?
Jest and Enzyme are both excellent tools for testing React UIs. Each is a functional testing tool that allows you to guarantee that your web application’s user interface appears and behaves as planned. Both are in active development and can be installed with ease using Node Package Manager.
Each has a robust development community that can assist a newcomer to the library if they run into a problem.
How are they different?
To start with the most obvious distinction, Jest and Enzyme serve slightly multiple functions. Jest is a powerful testing framework with a lot of features. That is, it does more than just assist you in testing React components.
The enzyme has a different function. The enzyme is a library that helps to test React components easier, rather than being a full testing library. It works with a variety of full-featured testing frameworks, including Jest. If you’re using React in your app, using Enzyme with Jest to test your UI automatically might be a good idea.
So, there are multiple ways a developer can test his React JS code. The most used frameworks as mentioned are Jest, Enzyme, Jasmine, React Testing Library, and Mocha. Each testing tool has its own advantages and disadvantages. The purpose of comparing Jest and Enzyme at the end was to allow the developers to know which framework best suits their React JS code.
So, choose wisely and get your hands on the testing skills!
