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.

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