I voted to leave closed specifically because of the point that Snow described as a distraction.
In my opinion too many questions on this site get closed as duplicates, or for other reasons, because we don't consider the specific details of each situation, and we assume that an answer that will work for one set of circumstances will work for every set of circumstances regardless of how much they differ.
I vote to leave most questions open based on this opinion, but this particular question is specifically about a coding problem, and the interpretation of that coding problem (as currently written).
A question about "how to convince your boss" would be useful to both the asker and others, but this question is not that.
A question about how to write better tests would also be useful, but not appropriate on this site.
