Many explanations : The drug tests do fail sometimes in a small group of people. Also, it depends on what exact they are testing you for, it is possible that they were testinf you for iliigal drugs specifically and you only take legal ones.

Drug tests: It is probably a combination of the tester using a cheap, lower sensitivity testing kit, testing during a low level of the drug in your system and you being a fast metabolizer. Oxycodone has a half life of about 3-4hrs. If you test several hours after your last dose the levels in you urine may be too low for the test to pick up. Also, only a small amount of the drug appears in the urine.
