What are some common errors in Jest async testing?

What are some common errors I might encounter when testing async code with Jest?

Some common errors include not returning a promise, forgetting to use 'async/await', and handling timeouts incorrectly.

Can you explain why not returning a promise is an issue?

Not returning a promise can lead to Jest not waiting for the async operation to complete, causing false negatives in tests.

What about using 'async/await'? Why is that important?

Using 'async/await' makes your code cleaner and ensures that Jest waits for the async code to finish before proceeding.

How can I handle timeouts properly in my tests?

You can set a timeout using Jest's 'jest.setTimeout()' method or specify a timeout in the test function itself.
