An Introduction to the React Testing Library
Daniel Afonso
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.

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!
