So, I made a task for my mashup with 1300 test cases. Verification was OK and I was able to package it. However, when judging solutions that weren't submitted from "Submit package solutions" i got Judgement failed(the package ones got 1300 points right away). Here's an example log: https://pastebin.com/1TrbxMJu . I noticed "Data too long for column 'judgeProtocol' at row 1" at several places, so is the only fix to have less test cases? If so, then is there a fixed limit for the number of test cases?
There's none of my business but why one could need so many tests?)
To question: once we used 200 test cases in inner mashup and tesing was couple of minutes which is too long for competition. I can't predict how much time would taken for 1300 tests.
I will say that I don't have a good answer. I saw that 25 tests were not enough and for some reason went overkill, so I added way too many tests when 50-200 better-made ones would've been a better solution. Anyway i'm currently deleting every 2 out of 3 tests, will delete more if necessary. I also noticed Polygon doesn't like deleting many tests at once.
Also you can have more tests in one test file, as Codechef does it.
