How can I test promises in JavaScript?
You can test promises in JavaScript using frameworks like Jest or Mocha. Would you like an example?
Yes, please provide an example using Jest.
Sure! You can use async/await in your test. Here's a simple example: test('fetches data', async () => { const data = await fetchData(); expect(data).toBeDefined(); });
What if the promise is rejected?
You can test for rejections using rejects in Jest. For example: await expect(fetchData()).rejects.toThrow(); Would you like more details?
