I graduated a couple of years back, but we would get tested about 6 times a year. It was all totally random. I only got tested about 5 times my whole career, and i was about 6'5, 300, and pretty shredded. I had always juiced, and everyone knew it. One of our quarterbacks was about 6'3 and maybe 190 at the most, and i swear, that fucker got tested every time. That proved that it was pretty random. No one would test that skinny fuck over some of the physical freaks that where on the team. If the school was going to test you, you would normally know the day before. If the coaches dont tell you, usually after the first person gets the call in the morning, it would spread like wildfire throught the team. If it was the school ran tests, everyone would just turn off their phones, and not take them. If the ncaa was going to test you, you would just get a call around 7 am telling you that you had 1 hour to get to the locker room and piss. If you dont show up, or if your late, you automatically fail. If your piss is diluted, or contains masking agents, you automatically fail. When you get there, you have to strip naked, and they actually stand there and watch the piss come out of your dick. The ncaa dosent fuck around with that stuff. So to answer your question, you may get tested, you may not. If you do, you are fucked.
