How do I handle async errors in Testing Library?

You can handle async errors in Testing Library by using the waitFor utility to wait for elements to appear or change.

Can you give me an example of using waitFor?

Sure! Here's a simple example:

await waitFor(() => {
  expect(screen.getByText(/error/i)).toBeInTheDocument();
});

What if the error doesn't show up?

If the error doesn't show up, you can set a timeout in waitFor to handle cases where the error might take longer to appear.

Is there a way to test if an error message is displayed?

Yes, you can use assertions to check if the error message is in the document after the async operation.
