I found a topic on this subject dated 2016 so I decided against a necro of that.
I occasionally work on a puzzle on this site and I appreciate the difficulty of many of these but when it is time to submit there’s a surprise dozen or so extra tests that are only presented as passed or failed.
This is now the second time where I had a single failure in the validators. I understand the reasons given for not exposing their contents although I also think that people that hard-code their solutions are really only hindering themselves but perhaps I’m missing some side-effects to this behaviour.
Anyway, to get to the point. If I’ve passed a dozen or so of the regular tests and another dozen or so from the surprise secret tests, and there is a single failure, I should at least be notified of the reason why a case failed, in particular if it’s a timeout. Just a column of all good and one red isn’t very helpful.
I’d like to see at the very least a time-out notification where applicable, “incorrect result” would be nice too or else some limited form of logging to the console where only the last line is displayed for all I care. At least it will give an indication of how far the code got or maybe that it even finished. But currently this has a bit too much of a “computer says no” vibe to it to my liking.
