How do I handle asynchronous tests in JavaScript?

You can handle asynchronous tests in JavaScript using frameworks like Jest or Mocha. They provide methods like 'done' or return a promise.

Can you give me an example using Jest?

Sure! In Jest, you can write an async test like this: test('async test', async () => { const data = await fetchData(); expect(data).toBe('expectedValue'); });

What if I want to test multiple asynchronous calls?

You can use Promise.all to handle multiple asynchronous calls. For example: const results = await Promise.all([call1(), call2()]);

Are there any common pitfalls I should be aware of?

Yes, common pitfalls include forgetting to return a promise or not handling rejections properly. Always ensure your tests are properly awaited.
