Delete the tests, or at the very least, Unlist them. Preferably delete, as soon as you get your answer.
For things you leave up, there are licenses. Buy them and follow their fine print. I stream a weekly church service, with the appropriate (paid) license, and I put the license number in the description. We can't monetize them, because they contain stuff that belongs to someone else, but we don't want to anyway. Never had a problem with it.
It was interesting though, to see a Chinese guy claim Amazing Grace, or something like that. (clearly our own performance of a clearly public domain song) We let it be, and it never went beyond that. It stayed up, and everyone's happy.
