Most times when using Vitest Browser Mode you will want to test against elements on the DOM, such as after rendering your React components with await render(<YourComponent/>).

But if you are writing React apps, sometimes it can be useful to test a React hook in isolation.

You can achieve this using the renderHook function (which is very similar to testing React hooks with React Testing Library):

import { renderHook } from 'vitest-browser-react';

This lesson we will quickly go over how to use it.
