I guess it could be tested via mocking, but I don't really have a problem with it not being tested to be honest - this code is basically "glue", and doesn't involve lots of complex logic. What I'm trying to avoid is the `app_test.rb` file growing to such a size that it takes a really long time to run, as I think that will make general development much more painful. So there's a balance to be struck - I don't think this test is problematic in itself, but if we have an acceptance test for every little thing like this it will start to really drag down the test speed.
