chai-datetime | common date equality assertions against JavaScript Date | Assertion library

I have written some tests in my Node project using Mocha and Chai. In one of my tests I create an agenda.js job, and then save it to the database. Then I retrieve that document from my MongoDB database and run some checks on it. After numerous configurations, I've found a construction for the test that works. But to get this to work I had to add a setTimeout() within the first it block, because otherwise the it checks start running before the document is retrieved from the database.

While the following construction works, I'd like to know what would be a better way of doing this. It seems to me the whole point of the before block in Mocha is to ensure that whatever work is defined within it is done BEFORE the it checks run. That doesn't seem to be happening in my case - hence the need for the setTimeout(). So how can I accomplish that without resorting to using the `setTimeout()?:
