      If it’s a 16-bit integer platform, it might hit every once in a while.

      If it’s a 32-bit integer platform, it’ll hit very rarely.

      If it’s a 64-bit integer platform, someone would have to do the math with some reasonable assumptions, but I wouldn’t be surprised if it would never hit before the universe becomes nothing but black holes.

        The point being made is that it also depends how often the ‘true’ value gets used in the code. Tests might only evaluate it a few times per run, or they could cause billions of evaluations per run. You can’t know the probability of a test failure without knowing the occurrence rate of that expression.

          Yes you’re correct, this was the point I was making.

          To elaborate: could be 100s of times in a codebase, even 1000s, being executed in tests on local machines and build servers 100s of times a day, etc. etc.

            But it would hit a different place every time… Most developers wouldn’t even consider checking for this, and the chance of getting a repro in a debugger is slim to none
