Is this course for me?

If you're writing React in any capacity, this course if for you! This course assumes a base level understanding of React, but whether you're working on small React side projects or full React applications at the day job, you'll learn how to test a variety of React components.

No prior knowledge of testing or React specific testing is required; we'll start from scratch and build up our testing knowledge over this set of ten videos.

Along with how-tos we'll also talk about characteristics of well written tests and how to avoid common pitfalls when writing tests.

What will I learn?

See below for a full list of topics covered in the videos of this course, but in a nutshell this course contains all you need to be confident testing a variety of React components. We'll cover:

  • The roles that Jest and Enzyme play in writing React tests.
  • How to test for UI changes in React components using Jest snapshots.
  • Testing React components that make HTTP requests by mocking HTTP requests.
  • Using Jest spies to mock behaviour in React components for testing purposes.
  • Testing React components that are connected to Redux, including how to test dispatching actions.
  • Using Enzyme's mount API to test lifecycle methods like componentDidMount and componentDidUpdate.
