I'm thinking with all existing explanations and if there is filled-in code written in the examples, below, it'll all come out in the wash. Thanks so much for all your hard work on it. I think ti's turning into something really understandable and great. :) The beautiful thing about building these testing guides is that we kind of **have to** explain the guts of Ember to explain what to isolate. I really like it. :) Tests as a pedagogical tool and documentation resource is a great thing. <3
