An example of an AI chatbot conversation about testing async code in Jest.
What are some effective strategies for testing asynchronous code in Jest?
When testing asynchronous code in Jest, you can use strategies like async/await, Promises, and the done callback.
Can you explain how to use async/await in Jest tests?
Sure! You can define your test function as async and use await to handle promises, making your tests cleaner.
What about using Promises directly?
You can return a Promise from your test function, and Jest will wait for it to resolve or reject before finishing the test.
Are there any best practices for testing async code?
Yes, always ensure your tests are deterministic, avoid using setTimeout for async operations, and clean up after tests.
