Will I get drug tested for trespassing?

Me and my friends were down at a place called "The barge" Its a place where you can jump off into the water. It is a private area and has signs of "Private Property" posted everywhere. I got arrested for trespassing and have to go to court. Will they end up drug testing me? There was no suspicion of drug usage and I don't have a record of any sort with the authority. First time going to court, etc.
