Testing React with Jest and Testing Library

Testing React with Jest and Testing Library

Learn best practices for testing your React apps with Jest and Testing Library!

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.
