What are some examples of async testing in Jest?

Async testing in Jest can be done using async/await or returning a promise. Would you like to see specific examples?

Yes, please provide an example using async/await.

Sure! Here's a simple example:

test('fetches data from API', async () => {
  const data = await fetchData();
  expect(data).toEqual({ name: 'John' });
});

This tests that the fetchData function returns the expected data.

What about an example using promises?

Here's an example using promises:

test('fetches data from API', () => {
  return fetchData().then(data => {
    expect(data).toEqual({ name: 'John' });
  });
});

This achieves the same result but uses the promise syntax.
