If you are going that route, just `unittest Johnny` would be fine.

But just to warn you, there's no place to store this in the ModuleInfo, 
it stores *one* function pointer for the whole file.

I personally am fine with the requirements to use a UDA.

And I also prefer the simple "first string" method, because one thing 
that is super-annoying is to have to depend on the unittest library for 
normal builds (I recently removed this for mysql-native).
