Are you doing something like, taking arguments

e.g:

ARGV[0].do_something

and you want to test this?

if that's the case, split it up into a library / script combo, and
make the functions testable

#---------

def do_it(arg)
  arg.do_something
end

if __FILE__ == $PROGRAM_NAME
  do_it(ARGV[0])
end

#------

Now you can test the do_it method by just requiring the file.
if you do this cleanly enough, there won't be much left to test in your script.
