Will I have to go to court, and if so, will I be drug tested?

Last night I was caught for curfew and brought home. The officer said I would probably be further contacted about this incident. I was already on police diversion for possession of marijuana, but today I completed it fully. Do you guys think I will have to go to court? If I do go to court, what are the chances I'll be drug tested? Thank you so much for you help, Truly
