This demand for automation testing has resulted in the development of JavaScript testing frameworks for satisfying various purposes. While some are intended for E2E testing, the others are appropriate for unit testing. It is not surprising that automation testers across the world have become too <strong>fond of JavaScript testing frameworks.<\/strong><\/p>\n<p>&nbsp;<\/p>\n<p>The different types of testing frameworks have made many individuals confused in the long run.

It offers decent cross-browser support and is used on a wide scale with Selenium for automated testing.<\/p>\n<p>An integrated framework is provided by Jest, which does not need any experience when it comes to the configuration. This tool is all set to use, and it would be possible to set it up instantaneously by running the command-<\/p>\n<p><em><strong>npm install &#8211;save-dev jest<\/strong><\/em><\/p>\n<p>&nbsp;<\/p>\n<h3><span style=\"color: #000080;\"><strong>The pros:<\/strong><\/span><\/h3>\n<ul style=\"list-style-type: disc;\">\n<li>One can consider Jest to be an exceptionally well documented and quick performing testing framework.<\/li>\n<\/ul>\n<ul style=\"list-style-type: disc;\">\n<li>A powerful developer tooling is provided by Jest with reduced error-prone code.<\/li>\n<\/ul>\n<ul style=\"list-style-type: disc;\">\n<li>It is also possible for this framework to execute visual regression tests. It captures screenshots for doing this. During the <strong>development of an application by using React JS<\/strong>, this particular feature is quite useful for preventing UI bugs. This is done by recording the rendered component\u2019s screenshot and comparing it afterward with components that have been rendered in the future.

However, it will be advisable to try out Jest, given that Facebook has been making lots of investments at present on this framework. Moreover, the <strong><a title=\"Hire React Developers\" href=\"https:\/\/www.rlogical.com\/hire-dedicated-developers\/hire-react-js-developer\/\" target=\"_blank\" rel=\"noopener noreferrer\">React developers<\/a> are also getting a positive experience after using Jest.<\/strong><\/p>\n<p>&nbsp;<\/p>\n<hr \/>\n<h2 style=\"text-align: center;\">Must Read: <a title=\"Best 9 Examples of Websites Built with ReactJs\" href=\"https:\/\/www.rlogical.com\/blog\/best-9-examples-of-websites-built-with-reactjs\/\" target=\"_blank\" rel=\"noopener noreferrer\">Best 9 Examples of Websites Built with ReactJs<\/a><\/h2>\n<hr \/>\n<p>&nbsp;<\/p>\n<h2><a href=\"https:\/\/mochajs.org\/\" rel=\"nofollow \"><span style=\"color: #333399;\"><strong>2. Mocha<\/strong><\/span><\/a><\/h2>\n<p>This one happens to be a <strong>JavaScript testing framework intended for testing apps running using Node JS.<\/strong> It is quite easy to install this framework.

Testing becomes <strong>much faster while using Jest, and not much configuration is required<\/strong>. Even though Mocha can boast of having a vast ecosystem, it is quite complicated as well.<\/p>\n<p>&nbsp;<\/p>\n<h2><a href=\"https:\/\/jasmine.github.io\/\" rel=\"nofollow \"><span style=\"color: #333399;\"><strong>3. Jasmine<\/strong><\/span><\/a><\/h2>\n<p>Mainly utilized for asynchronous testing, Jasmine happens to be a JavaScript testing framework that is full of innovative features. Running on Node JS allows flexible and accurate bug reporting by running the test cases serially.<\/p>\n<p>It is quite simple to install this JavaScript testing framework. You will simply need a workstation along with an Internet connection. The command <em><strong>\u201cnpm install -g jasmine\u201d<\/strong><\/em> must be executed in the <strong>cmd\/ terminal<\/strong> to install this framework. Nevertheless, as compared to Jest, the configuration is somewhat complicated. It is imperative to set up plus configure the test.js file before executing the test cases.<\/p>\n<p>&nbsp;<\/p>\n<h3><span style=\"color: #000080;\"><strong>The pros:<\/strong><\/span><\/h3>\n<ul style=\"list-style-type: disc;\">\n<li>Jasmine happens to be compatible across almost every library or framework of your choice, and this makes it one of the most flexible testing frameworks out there.

Otherwise, the process of configuration can be quite frustrating.<\/li>\n<\/ul>\n<p><span style=\"color: #000080;\"><strong>This framework supports-<\/strong><\/span><\/p>\n<ul style=\"list-style-type: disc;\">\n<li>Snapshot testing by making use of the snapshot library.

However, Jest will be ideal for you if the project is small and you are making use of React JS.
