I don't think golden files are a good way to test mojob -- the cost (of
maintaining a million golden files) generally seems to outweigh the benefits.

 Do you have a suggestion? You asked me to test this, but all this is doing is
taking a bunch of argument and outputting a list of command. I do not really
know how I can test this any other way.
