How do I handle errors in React Testing Library?

You can handle errors in React Testing Library by using the waitFor function to wait for elements to appear or disappear.

Can you give me an example of using waitFor?

Sure! You can use it like this: await waitFor(() => expect(screen.getByText(/error/i)).toBeInTheDocument());.

What if I want to test an error message that doesn't appear?

You can use queryByText instead of getByText, which returns null if the element is not found, allowing you to assert its absence.

Thanks! Are there any best practices for error handling in tests?

Yes, always ensure to test both the presence and absence of error messages, and keep your tests clear and concise.
