Oh, awesome! Thank you for putting this together. That's a lot of red on the code coverage report. I guess that's expected, but geeze...

On a practical level, what do you find is the best level to put the tests at? For example, we could test the page level functionality (can you subscribe to someone) but we could also test all the way down to the level of base methods (can you get a database handle, can you load a user's subscription list, can you add a subscription to the list).

The former implicitly tests the latter. But the latter will help identify where something has broken more quickly, although it involves more tests? Thoughts?
