How can I use Chai for asynchronous assertions in my tests?

You can use Chai's chai-as-promised plugin to handle asynchronous assertions. It allows you to assert promises easily.

Can you give me an example of how to set it up?

Sure! First, install the plugin with npm install chai-as-promised. Then, include it in your test file like this: chai.use(chaiAsPromised);.

What kind of assertions can I make with it?

You can assert that a promise resolves or rejects with specific values using expect(promise).to.eventually.equal(value) or expect(promise).to.be.rejectedWith(Error).

Are there any best practices for using Chai with async tests?

Yes, always return the promise in your test cases to ensure proper handling of asynchronous behavior.
