I know this is going to sound unhelpful, but if your task is to test the 
code, what good does it do to know what it does?  Clearly, it does what 
it does.  What you really want to know is "What is it *supposed* to do?"  
Until you know what it's supposed to do, it is meaningless to even think 
about testing it.

Seriously.  I'm not trying to make life difficult for you.  I've seen 
too much time and effort wasted on useless testing because there wasn't 
any specification for what the code was supposed to do.

I will give you one hint, however.  You've got stuff like:

for line in os.popen(cmd).readlines():
line = line.rstrip()

This is a syntax error because the indenting is wrong.  Unlike C#, 
indenting is significant in Python.  I don't know if the code you've got 
really is indented wrong, or it's just an artifact of how you posted it.  
But before anything else, you need to sort that out.

Unless, of course, the specification for this code is, "It is supposed 
to raise IndentationError", in which case it passes the test :-)
