Any automated testing is better than none.  For idlelib, I use unittest. 
  For an individual project with specialized needs, I use a custom test

There is usually a way to factor out the duplication of repetitive code 
like this.  Often, a dict is somehow involved. I believe the following 
is equivalent to the above.

else:
   action = options[0][0]
   try:
     globals()['do_'+action[2:]] = True
   except KeyError:
     print >> sys.stderr, progname + ': Unhandled parameter ' + action
     sys.exit(1)
