You will use Jest to write and run unit tests, and you will implement React Testing Library as a helper DOM ( Document Object Model) library to handle interacting with components. In this tutorial, you will test asynchronous code and interactions in a sample project containing various UI elements. Both Jest and React Testing Library come pre-packaged with Create React App and adhere to the guiding principle that testing apps should resemble how the software will be used.
React Testing Library offers a set of testing helpers that structure your tests based on user interactions rather than components’ implementation details. Jest is a JavaScript test runner that provides resources for writing and running tests. Obtaining solid test coverage is imperative for building confidence in your web application.
