It's always possible I've misread your comment, but if not: please don't dismiss other people's work in an assholish way on HN. It breaks both the site guidelines and the extra rules for Show HNs:
Substantive critique is welcome, of course, but in this case that would mean talking about problems with visual testing and making it clear you're not picking on this particular implementation.
Could you stop with the incredibly arrogant attitude? You wouldn't act like this in real life -- at least I hope not. You would be shunned by everyone around you.
