If you know what code you're trying to generate, you could use the
"gold master" approach, where you write a file with the code you want
to produce (the "gold master") and use that as the source of expected
values created by the generator. Using regular expressions or tools
like Hpricot you can do this incrementally.
It's not necessarily easy :) But it does let you write tests first.
