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

I solved it extracting try/catch to a function.

function asyncExpect(test, done){
    try{
        test();
        done();
    } catch(error){
        done(error);
    }
}

Then in it() I call:

it('shall update a host', function (done) {
            testee.insertHost({_id: 'host_id'})
                .then(response => {
                    asyncExpect(() => {
                        expect(response).to.have.property('ok', 1);
                        expect(response).to.have.property('nModified', 1);
                    }, done);
                });

        });

It's also debugable.
