[TIP] Functional Test Runner for Command Line Tools?

[Noah Gift]

In looking at http://pycheesecake.org/wiki/PythonTestingToolsTaxonomy
I don't see something that automates writing functional tests for
command line tools.  Hopefully, I am wrong, but I am looking for
something that will fully exercise a command line tool easily.  How is
everyone else testing their command line tools?


Cheers,

Noah
