How can I test asynchronous functions with Testing Library?
You can use the waitFor utility from Testing Library to handle asynchronous operations in your tests.
Can you give me an example of using waitFor?
Sure! You can wrap your assertions in waitFor like this:
await waitFor(() => {
expect(screen.getByText(/loading/i)).toBeInTheDocument();
});
What if I need to mock an API call?
You can use libraries like msw (Mock Service Worker) to mock API calls in your tests.
How do I set up msw for my tests?
First, install msw, then create a handler for your API endpoint and set it up in your test file.
