jest-dom is a companion library for Testing Library that provides custom
DOM element matchers for Jest
Then follow usage section from jest-dom's documentation to add the matchers to Jest.
Note: when using some of these matchers, you may need to make sure you use a query function (like
queryByTestId) rather than a get function (like
getByTestId). Otherwise the
get*function could throw an error before your assertion.
Check out jest-dom's documentation for a full list of available matchers.
