I couldn't really think of anything to test, you know? No function exists to test (which is the point), and nothing happens (which is also the point); I just wanted to verify that the code runs and doesn't 'splode. One might think to test that the eventsHash doesn't try to attach the function that doesn't exist, but it seems like that's all handled internally, so there's no way to extract it.

That seems like a significant-enough test for what I was trying to do. If you can think of another way to show this that you think is more substantial, I'd be happy to implement it.
