For the example I gave: 
=item addgroup

Takes one parameter, which may optionally be named 'group'.
We detect whether it is a named parameter or not by checking
for the presence of 'group' followed by anything else in the
arguments.  This should be a valid groupname (ie consists
solely of word characters) which does not exist.  If that's
OK, an empty group is created.  All errors are fatal.

I'd want to somehow encode that so that it could spew out the tests to make sure it dies if the number of arguments is wrong or if the one significant argument matches /\W/. This would be several tests. I would then add tests manually to make sure it dies if the group already exists, and to make sure it creates a group correctly.
