Testing a Custom React Hook (useMap)

Developers of the most popular React Hooks libraries rely on tests to enforce the overall quality of their libraries' code. Tests cover a wide variety of different use cases, give developers confidence that everything works as intended and serve as a form of documentation. Anytime a test fails, developers know which set of arguments to use to replicate the bug encountered and squash it lands in the distribution package. When writing a custom React Hook for a library, the Hook should be tested regularly and against the fringest of edge cases to appeal to a greater number of projects. Setting up a testing environment that executes tests fast and reliably requires the proper tools: This testing environment allows you to write tests that closely resemble your user's actions. For example, @testing-library/react comes with methods for rendering a React component ( render ) to a container ( document.body by default) and finding an element within the rendered content of this container via the element's label ( screen.getByLabelText ):
