short answer=no
you can see if they exert any pressure when you compress them..thats about it...you're not going to be able to simulate the 7500 lbs of pressure from your truck bouncing quick enough to test..
even in my off road rig, I won't run used ones....its not worth the hassle of putting them on a couple times, I'd rather do it once and be done
hope that helps

Thanks. They're not for me. Someone is interested in buying mine that I pulled off when I went to a smaller lift. I only had the truck for 2 weeks and don't know for sure how old they are. He is wanting to know for sure if they are good before he buys them, so I was hoping that there was a good way to test them. Thanks for the help.

Stand em up for a few minutes so any air in teh shock gets to the top, then compress tehm and see if they are smooth the whole way. If you get a spot where they compress more easily there is air in emdue to the oil leaking out. Other then looking for signs of leaks thats about all I can think of. Some run with compressed nitrogen and other fancy stuff and I'm not sure how to check if its lost its charge.

testing shocks
depends. Are they OEM type ? Or "after-market". Let me give you a little background. Most OEM shocks are designed to only provide shock absortion on the RE-BOUND, meaning, when you compress them, you should feel practically NO resistance, it should be VERY hard, once compressed, to pull them out to full extension. If you can easily pull them OUT, toss em.
After-market shocks typically give a "firmer" ride, because they provide resistance BOTH on compression AND on extension. My experience is that an after-market shock will, if it is any damn good at all, be too hard to really pull apart or compress with just human-power.
