An example of an AI chatbot conversation about setting up Jest for async tests.
How do I set up Jest for testing asynchronous code?
To set up Jest for async tests, you can use either Promises or async/await syntax. Would you like a code example?
Yes, please provide a code example using async/await.
Sure! Here's a simple example:
test('async test example', async () => {
const data = await fetchData();
expect(data).toBe('expected value');
});
This test waits for fetchData() to resolve before making the assertion.
What if I want to test a function that returns a Promise?
You can still use async/await. Just ensure your test function is marked as async and await the Promise.
