Can you make this unit test work with more than one object?

[dougt, 2017/06/25 21:16:32]

Done.

[dmazzoni, 2017/06/23 18:51:12]

Shouldn't it return a dispatch if it's anything other than "self"?

[dougt, 2017/06/25 21:16:32]

Done.

This was because our hit test testing code would just return self.  I've updated
test to look for a dispatch (and test that we got the right now), and updated
the testing code to be more sophisticated.
