When you are testing, does officer supervision work, im pretty sure a 1v1 test can prove it.
In fact I've tested things with people before. 1v1 is fine for testing.
Yes, that is how the procedure goes
when you already know what you're looking for. I came up to Elitegren and said precisely that, we tested it, and I reported the bug.
But the extremely simple fact of the matter is that 1v1s like that are only good for CONFIRMING that the bug is there. You must already KNOW what you're looking for before you start being able to derive any use at all from them - and the use that you will get is, flatly : the mere confirmation the bug exists.
You still need the random-pattern testing in which you just pin point the possible bugs via regular standard gameplay.
