Learn how to use React Native Testing Library to quickly and efficiently write tests for your React Native app!

Get Started

Last Updated: Feb 22nd, 2022

When we test our the components and functions of our app - how do we want to do it? The same way a user would use them!

That's where React Native Testing Library comes in! It gives us the capability to test the various components of our application in the same way a user would actually use them by allowing us to press a button, type into inputs, and more.

It integrates perfectly with Jest and is the first library that makes me want to write tests for my apps. I can't wait to share the library with you!

Great course! Spencer's explanations are very clear, concise and to the point. Video playback quality is also good, which is a big reason I chose this course over some courses on Udemy.
