A shock dyno is the preferred test. You might be able to do a little googleing and find a setup for a home brew shock dyno. Otherwise, if they push in slow an come out by themselves, I would call it good.

Now you got me worried. The shocks came in the full down position. It takes a lot of force to pull them out to the fully extended position. Once in the fully extended position they remain fully extended, they don't come in by themselves. It is relatively easy to push them back down.

they're bad. Shocks should always be in the fully extended position unless under a load.
Complain, get your money back (unless sold as is...)
Not necessarily, that description only holds true if they are gas charged.
I've had brand new Koni shocks that could be compressed very easily yet would take ten men and a boy to pull them back out (adjusted to max dampening).
So if these shocks are not gas charged there maybe nothing wrong with them.
Just food for thought....

they are better know as dampers in performance cars.. shocks make sense for huge american boats..
I think it makes sense that as a car hits ripples in the pavement to use the shock to hold the car down.. (wheel up)? or does it..?
you want the wheel to move up freely over a bump, (compress the damper) then have the entire weight of the car, pushing the wheel back down.. if the bump is over the body will slowly rise as the shock extends... ready for the next bump.

Performance oriented shochs will usually damp heavily in bump (compression) and rebound (extension). In other words, it should be difficult to make them move in either direction. And no they won't automatically extend due to internal pressure. A good shock/damper, should want to stay still and not move in any direction.
On my adjustables, I am unable to move the piston at all on the stiffest setting. But on the softest setting, it isn't too hard to move. When a shock is dead, the weight of the piston will make it move by gravity alone. Though rebound and bump are seperate valves, and one can fail without hurting the other. So it may be easy to compress but difficult to extend. Also vlving for fast movements and slow movements are different too. So the shock will move easily when moved slow, but still be difficult to move when moved fast. They would still suck to drive on theough, so I'd call them dead.
This is different for every shock, because each brand has different valving.
