Jest is one of the best tools available for testing React applications. This course will teach you basic and intermediate Jest testing techniques, including running tests, snapshot testing, testing React components, and module mocking.
At the heart of building durable and reliable React applications is a solid understanding of testing, starting with Jest. In this course, Testing React Applications with Jest, you will learn everything you need to do to create solid tests for your React components and applications. First, you’ll learn how to install Jest on any machine, run tests with it via the command line, and integrate it with any Node project. Next, you’ll dive into the various testing techniques, including globals, mocking, and snapshot testing that you can use to make your tests more readable and efficient. Finally, you'll explore how to use all these techniques to test React components and the applications they belong to. When you’re finished with this course, you’ll be able to immediately start writing tests for your React applications, discuss testing strategies and techniques in the workplace, and facilitate development by setting up and configuring Jest.
Course Overview React applications are the preferred way of delivering content to clients and customers over the web, but without good testing, knowing if your application works as expected is a matter of guessing and luck. In my brand-new course, Testing React Applications with Jest, you'll learn how to test React applications from the ground up. We'll learn how to install Jest and integrate it with a new or existing node application. We'll learn about running tests with Jest, but we'll also learn advanced techniques. You'll learn how to scaffold tests using mocks, and how to create automatic tests with snapshots. Finally, we'll learn how to test fully-featured React components using all the techniques I've just mentioned and more. By the end of this course, you'll have written and learned to manage multiple kinds of tests by coding along at home during the demonstration portions of this course. Full-course files are available for you to study and to use in your own projects. Before starting this course, you should be highly familiar with React applications. If you're not already familiar with React, I recommend my recent course Isomorphic React, which is available here at Pluralsight. If you're already a senior React developer, feel free to jump right in. Don't rely on guess work and random chance when building applications that are reliable, durable, and progressive.
