(Newswire.net — September 14, 2020) — Creating a website involves several processes before going live. You should first look for the right platform to develop your website. React Native is a great platform for building native apps. Here are some killing facts about React Native explaining why it is the best open-source mobile and web application framework. The other vital process is testing. This can help you understand if your website is ready for use.
There are various methods or options you can use to test web applications. Most developers have set these testing methods into libraries that can be used again. You will come across a wide range of react testing libraries that can be used to test a react web application. How about you jump here for React Acceptance Testing and more on this essential phase in development. Different testing libraries have their pros and cons. Let’s look at some of the best reacting testing libraries you can use for your project.
React Testing Library
This is a lightweight solution used to test react components. It functions on the top of react-dom and react-dom/test-utils. This particular library works with DOM nodes but not rendered components. Some of the companies that used it include Africa Code, page-builder, Commercetools, MPB, and Hiverbrite. There are several benefits linked to react testing libraries.
It has all the DOM testing utilities and is also easy to duplicate user actions and workflow with the react testing library. It is also capable of testing behavior and can be linked with various frameworks like Vue, Angular, and React. You can checkout this examples of tests carried out in the react testing library. The only downsides you will experience are difficulties running a single test and several error messages from a single error.
Jasmine
It is another great react testing library widely used for testing JavaScript code. Jasmine doesn’t rely on any other JavaScript framework or library. It is independent of DOM and browsers. Jasmine is widely used by known companies like Gitlab, Walmart, Accenture, etc. One of the benefits of Jasmine is that it is open-source and independent. It does not rely on DOM. This particular library is quite easy to use, and configuring it is very simple. Jasmine can also be used with test-driven development. The downsides you are likely to experience from using it include difficulties in asynchronous testing, and it requires .specjs.js extension for every file that has to be tested.
Mocha
It is a testing framework meant for Node.js. Mocha can run in and out of your browser. You can also do asynchronous testing with this particular framework. Some of the companies that use Mocha include Coursera, Asana, Typeform, and Accenture. One of its key benefits is that it supports asynchronous testing. Mocha is easy to use, and it’s also available for open-source projects. It is flexible, and generator support can be easily added. You are likely to experience very few challenges when using this particular framework. Tasks like adding a snapshot may require more tools with Mocha.
Jest
It is a react testing library that is highly preferred by most developers. Facebook maintains Jest. This particular library works with projects using Vue.js, Node.js, TypeScript, Angular, and react. Some of the companies that use it include Airbnb, Revolut, Uber, Instagram, and Facebook. It is simple to use and available on Node Package Manager (NPM). One of its benefits is that it supports parallel testing. Jest can bundle with JSDOM, making it the best for DOM testing. It also has great documentation. One of the disadvantages you’re likely to experience from using it is that it is difficult to run a single test. You can also get several error messages for a single error.
