99% of the work is in coming up with the edge cases, and in law the most common thing to do with edge cases is call them out explicitly. I imagine the legislator went back and added a clause to the law that specified "it shall not be considered a violation of this section for a minor to send photos of themselves".

Laws don't need to be computer-executable, they're about intent and the interpretation thereof, so the test suite itself is really part of the law and may as well just be embedded in it.
