Summary

In this chapter, we gave a basic overview of how to test React apps. Jest is a testing library developed by Facebook, and it is already available in our frontend because we created our app with create-react-app. We created a couple of tests with Jest, and ran those tests to see how you can check the results of tests. We installed Enzyme, which is a test utility for React. With Enzyme, you can easily test your React component rendering and events. In the next chapter, we will secure our application, and add the login functionality to the frontend.
