The problem is that you must make sure you actually test the student, and not some other student, or a team. That's even harder for "take home" projects, because the time for exchange is so long.

I try to formulate most of my questions to not be just knowledge. With higher classes, I care less and less about how much they know, or just know how to find it, because the real problem is figuring out what they need to know, so to speak. For lower classes, this is a lot harder, because these classes often teach the basics required. You cannot be a good physicist if you have to google F=ma every time. The same way you can't be a good programmer if you SO-search for -loops.
