How can I test custom hooks in React using React Testing Library?

You can test custom hooks by creating a test component that uses the hook and then rendering it with React Testing Library.

Can you show me a simple example of that?

Sure! First, create a custom hook, then write a test component that uses it. Finally, use render from React Testing Library to test it.

What about testing hooks that use context?

For hooks that use context, wrap your test component in the context provider when rendering it in your tests.

Are there any best practices for testing hooks?

Yes, keep your tests isolated, use meaningful names, and ensure you cover different states of your hook.
