Testing React with Jest and React Testing Library (RTL)

React Testing Library has become an extremely popular option for testing React, and with good reason! This detailed, comprehensive course  provides a solid foundation for React app tests.

Best Practices

React Testing Library is famously opinionated about testing best practices, and is written to encourage these best practices. This course teaches:

testing behavior over testing implementation

tests that interact with your app the way a user would

finding elements by accessibility handles, to make sure your code is accessible as possible

Broad range of testing examples

The course apps start very with very simple examples (clicking a button to change its color) and work up to progressively more complicated testing concepts, such as: 

testing asynchronous page changes

simulating data from a server using Mock Service Worker

applying a context provider to a component when rendering

The course builds up to complex concepts gradually, in a way designed to support your learning and ensure your success.

Practice your new skills

You will also have plenty of opportunities to practice what you’ve learned. The course provides code quizzes while building the course projects, where you can apply what you learned and then watch a video to see the solution. The (optional) final section provides even more exercises to complete the second app and reinforce concepts from the course.
