Is there a way to get Chai working with asynchronous Mocha tests?

Question

I\'m running some asynchronous tests in Mocha using the Browser Runner and I\'m trying to use Chai\'s expect style assertions:

window.expect = chai.expect;
d         


        

Answer 1

I asked the same thing in the Mocha mailing list. They basically told me this : to write asynchronous test with Mocha and Chai :

• always start the test with if (err) done(err);
• always end the test with done().

It solved my problem, and didn't change a single line of my code in-between (Chai expectations amongst other). The setTimout is not the way to do async tests.

Here's the link to the discussion in the mailing list.
