How do I set up async/await in Testing Library?
To set up async/await in Testing Library, you need to ensure you're using the latest version of the library. You can use async functions in your tests by marking your test function as async and using await with the Testing Library's queries.
Can you give me an example of a test using async/await?
Sure! Here's a simple example:
import { render, screen, waitFor } from '@testing-library/react';
import MyComponent from './MyComponent';
test('loads and displays greeting', async () => {
render(<MyComponent />);
await waitFor(() => screen.getByText('Hello, World!'));
});
What if I need to mock an API call?
You can use libraries like jest.mock
to mock API calls. For example:
jest.mock('./api', () => ({ fetchData: jest.fn() }));
