In the previous section, we learned how to update production dependencies and add component tests to legacy applications. In this section, we will learn how to replace existing legacy tests written in Enzyme with React Testing Library. Before React Testing Library was created, Enzyme was a popular library to test the UI of React components. Enzyme is a great tool, but the design of the API allows the implementation details of components to be tested, resulting in developers having to update test code frequently as they update their source code. We will replace legacy Enzyme tests with React Testing Library to resolve the problem of having to update tests that focus on implementation details continually.

We will use this approach to refactor legacy Enzyme tests to keep the current tests while installing and incrementally refactoring them with React Testing Library. Please refer to Chapter 2, Working with React Testing Library, for installation...
