The best solution is the non-technical one:  an alert marker.  I know that
when I did serious marking for the first time, I was startled at how easy
it was to spot this sort of thing.  Made me glad I'd never tried it...

(The closest I ever came was in an assignment where I'd gone a bit beyond
the specs and added an extra feature.  As submitted, none of my test data
used it.  I got docked a bit for incomplete testing, and the marker (who
was a friend) asked why I'd goofed up like this.  My reply was that it was
a simple last-minute mistake; the real reason was that the extra feature
had a subtle bug which I didn't have time to hunt down.)
