So if there is an expected output file, then run_tests.py will continue to do
the comparison as now.  However, if there is no output file it will instead
just run the code - which presumably will throw an exception if something is
wrong (even just an assert statement)?

I haven't looked at run_tests.py to see how easy such a change would be, but in
principle it sounds fine.
