The skills acquired from this course will allow you to write automated tests on your React app using Jest and React Testing Library, which are the de-facto testing tools for React. These tests will allow you to ship new versions of your app with confidence. The tests will also allow you to increase your release frequency, allowing you to get features to your customers quicker. You will learn how to write robust tests that are resilient to breaking when code is improved and refactored, reducing maintenance costs. The course will teach you how to simulate a user interacting with the app. Beyond that, it will also teach you how to robustly test asynchronous parts of the app. Regular quizzes and exercises will reinforce knowledge throughout the course.
