First Time Tester

So, I bought one of those 88 cent tests from Walmart earlier kind of as a joke. I've actually never even taken nor seen a test before in person. I kind of just wanted to see what it was like to take one. I really wasn't expecting a positive result. It came through almost instantaneously once I put in my urine. Does that mean it could be faulty? It said it takes at least 60 seconds but it literally took about five.
