Then I decided to write a practical starter guide for unit testing in React, including Redux, to share what I learned. So I took some time to read the Redux documentation and went back and forth with it a bit. However, as I myself was learning React, I had a hard time finding information about how to implement tests for libraries like Redux (even though it's a library I work with all the time).īeyond that, I found that doing any component testing in React is basically unfeasible when you don't know how to work with the Redux library. Being able to work with automatic tests is also quite handy for any upcoming frontend developers. While learning advanced concepts of React, you'll probably stumble across the topic of testing. I'm using the npm installation approach, not the yarn one.You don't need any prior knowledge about testing.You should have a basic knowledge of Redux (I'm using Redux Toolkit for this guide).You should be familiar with the basic React workflow structure (including functional components and hooks).You'll get the hang of why Test Driven Development (TDD) is helpful for your coding workflow.You'll improve your general React knowledge. You'll see how easy it is to set up your first unit tests in React.You'll learn how to write tests for Redux states as well as fundamental Redux slice tests using the React Testing Library and Jest. In this step-by-step tutorial, you'll learn how to easily start with Unit Tests in React.
