Summary
In this chapter, we learned how to write tests for our JavaScript frontend application based on React, React Router, and Redux. We also provided complete test coverage for the task manager’s features by implementing a complete portfolio of unit and integration tests. We started by learning about the required and recommended dependencies to implement our tests and added the missing ones. Then, we developed tests for our React components and our React Router configuration. We also wrote tests to verify the application’s features from a user perspective and learned how to run them from the command line.
You should now be able to implement tests for your JavaScript frontend applications based on React, React Router, and Redux Toolkit using Jest, MSW, and React Testing Library. In the following chapter, we’ll integrate the frontend and backend projects and create an API gateway in Quarkus so that the frontend application can be served from the backend.
