Why React JS is better and How to test it?

The era of technology is evolving with time introducing an immense amount of new react js development technologies, frameworks, languages, libraries, and much more to make our work/business even more comfortable and unique. But, it has also make it difficult for us to choose wisely to get the maximum out of it.

If we observe the front-end development, we know that Angular is the most basic and commonly used framework worldwide for all software businesses, be it online or on-site. With the evolution, React js development services have become popular among all the front-end developers and software service businesses.

What is React.js?

The creator of React, Jordan Walke, defines React.js as the most efficient, propositional, and easy-to-use framework that allows the developers to make simple and fast front-end web applications.

It is a Javascript library that is run and monitored by Facebook. Research has shown that React has become the most used or loved framework up till now. Let us jump into some critical benefits of React that make it the most loved framework!

The Key Benefits Of React JS? 

Here are some of the key benefits of using React JS as a development framework. 

It’s easy to learn

As we have mentioned earlier, React has gained such popularity in such a short time. The main reason behind this is that it is easy to learn. The more it will be easy to understand, the faster one will be able to build its projects. We know that as human beings, if something takes more time to learn or make, we get frustrat or shut the task, but now businesses are more inclined towards React due to its simplicity.

It helps to develop great interfaces:

Another feature that makes React more adoptable is that it helps to develop high-quality user interfaces. This feature is consider to be the most important as if the user interface of any web application is not eye-captivating, users will have zero interest in using that application. So, to build well-off UIs, one must use React so that users can enjoy it while interacting with it.

It allows writing custom components:

React JS is flexible enough to provide the developers with “JSX” feature. This feature allows the developers to write their components while building any web application. A developer can make their part unique by customizing it concerning the nature of the code. It accepts HTML code and converts its mockups into ReactElement trees. This improves the quality of the application. 

It allows great SEO:

React offers fast rendering, which allows the application to run in as low a time as possible. This feature helps the applications appear on the top of the Google Seach Engine Result Page. We know that the lower the page’s loading time, the faster it gets the rendering speed, ultimately allowing the application to get to rank on Google. 

It makes your code stable:

One more salient feature of React is that it makes your code more stable. As the data flow is downward while inheriting any child component, it will not affect the parent component if you make proper changes/modifications. This will bring stability and efficiency to your code, making its quality even better.

In addition to these, there are many more benefits like it can extend your tools and abilities, make templates get design easy, provide a strong support community, and many more. But, now we will discuss the testing importance and frameworks.

Testing is crucial while using React JS as a development framework?

Error is something that can make any code unprofessional, unreliable and poor. If more than two developers are working on a single application with unique requirements, there would be many chances of errors and bugs, which should be eliminated beforehand. 

That is why testing any software is necessary so that the quality and performance of that software cannot be compromise. It sends a wrong impression to the client if any bug is left undetected while presenting the demo to them. 

Testing is consider significant as it ensures that the code/application/software presented to the client is bug-free, reliable, high quality, and will perform best when run. 

Ways to Test React JS:

Following are the three best ways to test React JS to make your software even better:

React Testing Library:

React Testing Library is the commonly used testing solution for React JS. It provides the best testing practices using utilities like react-dom and react-dome/test-utils. These utilities query the/investigate the components as any real user would while using the software.

To test the code, you must first understand it and make arguments accordingly. For testing, at first, you will use a render command to render the component you want to test. Then import the App components to build two different arguments to start the test call, i.e., a string representing the test name and a function for the code we need to test.

By following these steps, we render the functions from React Testing Library and find the h1 element if it there in the DOM or not. To run the test, give the command “npm run”.

JEST

Jest is mainly a testing framework for JavaScript, and Facebook has maintained it to monitor React applications. It has the following features:

• It allows multiple tests at a time without creating any conflict among them. Also, no single trouble can be make by any global or local module states. 
• Another feature related to the part mentioned above is that it can easily manage to test larger or smaller codes as it runs different tests in parallel.
• While using Jest coverage, no additional tool is required for the purpose.
• Lastly, it is easier to use.

Enzyme

The Enzyme is also a popularly use testing solution for React Js. It enables the user to test the output of the code by exploiting crosswise, rendering components, etc. 

To use this specific testing tool, you need to make your React app aware that the Enzyme is install and available and export all the outputs to be test accordingly.

The two main functions of Enzyme are as follows:

• Shallow that allows the component to be load into the memory.
• Mount which loads the full DOM tree.

FINAL THOUGHTS: 

So, this blog post will refer you to all the pros related to React JS Development Services, along with the best testing tools to test your code. It has two main segments. The first is relate to the introduction of React and its benefits that make it more popular among front-end developers. These benefits state that it is easy to learn, has high speed, provides flexibility for custom codes, is SEO friendly, provides stability in your code, and much more.

The second and the last section is all about the testing of React JS. This segment states the significance of testing and different ways to test React Js code in the best way. The three most popular ways have been mention, i.e. React JavaScript Library, Jest, and Enzyme. The functionalities and benefits of using each testing tool is mention. So, there is all you need to know about why React is better than any front-end framework or how and why to test your React Js application to make you stand out from others by using the mentioned information.
