Best React Native Testing Tools

#1 Detox

An end-to-end testing library which is used to develop react native applications. With Detox, you can stimulate the user behaviour by testing your apps automatically for how users will react to it. The challenge which react native apps used to face was for the E2E automated testing. But, thanks to Detox who solved this problem.  


This react native testing tool was developed from scratch to support the projects of pure native ones. The mobile apps here are tested when they are running on the simulator. Detox is specially used for the gray box testing.         

 

#2 Jest

One of the most popular testing frameworks developed by Facebook. The react native developers use this tool to test each JavaScript component with react native applications. Jest is being used by Uber, Airbnb, and many such popular frameworks. This shows that you can use the framework with the big projects too.


This react native testing tool comes with assertion functions and test runners. Jest will suit best to the beginners who are working to improve incredibly fast javascript codes. In addition to all, it includes various functions like parallelization, async method tests, snapshot, and much more. Jest framework has a standard syntax with an accurate report guide.     


#3 Enzyme

A JavaScript testing tool which is used to test react native apps for various react native components and check the outputs for the same. When you know the output, you can also simulate, manipulate and traverse the runtime. The framework is developed and maintained by Airbnb.


Get access to the business implementations of the components of your react native app. All in all, Enzyme is used to access things, find elements, simulate events, interact with elements, render components and so on. You can even conduct a full DOM rendering of components with this react native testing tool. If you want quick testing, then you can opt for shallow rendering with Enzyme.         


#4 Cypress

Cypress is one of the fastest end-to-end testing frameworks which lets you write the tests without the need for any other testing frameworks. The best part of this react native testing tool is while testing you can even keep using other tools side by side. The tool comes with a control panel which will give you complete control over the tests.    

A few benefits of using Cypress are automatic waiting, screenshots and videos, time travel with snapshots, control network traffic, and so forth.       


#5 Karma

The tool aims at developing a product testing environment which works well for the developers. It is all about letting developers just write the code without worrying about the configurations. To the fact, you can test codes on real devices like phones and tablets with this testing tool.


Karma is able to control the complete workflow from the IDE. All you need to do here is just save the file and rest will be taken care of by Karma. Above all, the tool allows you for the integration of Travis, Jenkins or Semaphore.
