I don't think unit tests are that helpfull in this case.
Unit tests help you in finding out there is a bug, they
don't help that much in tracking down a bug.

I for some reason a person is reading over the difference
between sumLongName and someLongName and doesn't notice
the different spelling in his source a unit test won't
be of much help.
