I recently had to deal with this problem. I ended up testing the
parsing/printing by parsing a file, printing it out, and parsing the
print-out, and then making sure the ASTs built up are structurally
identical (modulo any position fields you might have lurking in your
ASTs).

I have to say, ever since I did this testing, I have had no problems
with my parser.
