@polesye Actually, I take that back. Now that ```comparator``` has been removed from the ```notes``` collection, we are not testing ordering in Jasmine as per say. Just that the order in which models are added are unchanged in the rendering. So I would say 

```it('should display notes in the same order as they were added as well as their corresponding text and quote'...```
