An Introduction to the React Testing Library

In 2018, Kent C. Dodds wrote: "The more your tests resemble the way your software is used, the more confidence they can give you." This phrase became the guiding principle for the entire Testing Library ecosystem.

A few years later, the React Testing Library became the de facto library for writing unit and integration tests in the React ecosystem.

Thanks to its user-centric perspective, our tests are closer to our user experience and far away from implementation details.

In this course, you will learn how to:

• render your components
• properly query your UI for elements while keeping accessibility and your users' experience in mind
• improve your testing experience with the usage of some utilities
• interact with your components to fire events
• leverage asynchronous utilities to customize your testing flow
• get rid of the annoying "not wrapped in act" warning

After this course, you should be able to write and debug any test using the React Testing Library!
