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!
