Builds and passes spec for returning the view's el from the render function. I'm mostly doing this because otherwise my spy in the posts index view would interfere with appending post_view.render.el. It also makes sense to me that the render function would return html. Not sure why the whole view would be necessary.
Puts my own collection in place of the dummy collection in the BeforeEach of the posts index view spec. Builds the collection to make the specs pass again. This is bad TDD. I should have built specs for exactly what I wanted from the beginning.
Builds and passes spec for parsing JSON to create a comments collection when instantiating a posts collection.
Builds and passes spec for filtering posts by popularity. Refactors isPopular into a function on the post model. Builds and passes specs for instantiating a posts router and starting Backbone.history.
