What are the best practices for using async/await in Jest?

When using async/await in Jest, ensure you return the promise in your tests or use the 'async' keyword.

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

Sure! Here's a simple example:

test('fetches data', async () => {
  const data = await fetchData();
  expect(data).toEqual(expectedData);
});

What should I avoid when using async/await in my tests?

Avoid mixing async/await with callbacks or not handling promise rejections, as it can lead to unhandled promise errors.

Are there any specific Jest configurations I should be aware of?

Make sure to set the 'testEnvironment' to 'node' if you're testing server-side code, as it can affect async behavior.
