What's this test checking? :)

I'd like to check that it displays the window, but I don't know how to do that
yet.  Right now I just want to ensure that we can build and compile and run the
basics of our windowing system in the unit tests.

[halliwell, 2017/01/24 04:10:12]

Fair enough.  Maybe can find some useful assertions to make in other aura tests?
