How do I test Higher-Order Components in React?

To test Higher-Order Components (HOCs) in React, you can use libraries like Jest and Enzyme or React Testing Library.

Can you give me an example of testing a HOC?

Sure! You can create a simple HOC and then write a test that checks if it renders the wrapped component correctly.

What about testing props passed to the wrapped component?

You can use Jest's toHaveBeenCalledWith to assert that the wrapped component receives the correct props from the HOC.

Are there any best practices for testing HOCs?

Yes, keep your tests isolated, mock dependencies, and ensure you cover both the HOC's logic and the wrapped component's behavior.
