How do I handle promises in React testing?

In React testing, you can handle promises using async/await or by returning the promise directly in your test.

Can you give me an example of using async/await in a test?

Sure! You can write a test like this:

it('fetches data successfully', async () => {
  const data = await fetchData();
  expect(data).toBeDefined();
});

What about using Jest with promises?

With Jest, you can return the promise directly:

it('fetches data', () => {
  return fetchData().then(data => {
    expect(data).toBeDefined();
  });
});

Are there any best practices for testing promises?

Yes, always ensure to handle both resolved and rejected states of the promise to cover all scenarios.
