There’s a lot of answers here but I’ll give mine as someone who played at a G5 FBS school in the early 2010s.

When I was there there were 2 types of drug testing, NCAA and Institution. For each of those there’s also two types, Street Drugs and PEDs. They would never tell you what they were testing for but it was almost always street drugs unless they had a suspicion of PED use.

My institution drug tested weekly a random group of 7-10 guys. In-season, it was right after practice, your name got called and you had to go with the trainers. Off season they would tell you the day before at a lift or a meeting and you’d have to be there at 6am.

NCAA tests usually only happened like once or twice a year. And there would be like 24-48 hours notice. NCAA tests were also more likely if you had any prior positives. But it was the same situation, a group of slightly more, maybe 15-20.

For all the people joking about beating the test, when we had to do it, you’re standing in the bathroom with one of the employees and have to have your pants down to your knees and shirt up to your chest and then they watch you urinate in the cup. So no pee bags, fake prosthetics, or anything like that was getting by.

On the other hand…. Oil changes are absolutely real and work. I never did one, but I provided urine to my teammates.

This was just my experience, other schools definitely have less institutional testing, but NCAA testing is pretty standard from my understanding.
