[TIP] Writing Separate Functional Tests

[Noah Gift]

I have a gigantic threaded beast I need to test, and I want to write  
functional tests that supplement the doctests and unittests, but  
wanted some advice on the proper way to do this.  I have not seen much  
documentation on writing non-web functional tests, my tool is a CLI  
tool. The basic thing I want to verify is that my tool creates a XML  
file with the information I would expect to be there.  For example, is  
there a selenium equivalent for command line tools?
