Testing Relays

[ForeverNight]

So, we broke 3 of our 5 relays last year and, like idiots, forgot to label or throw away the broken ones. Now, as head of electrics I've inherited this problem from last year's team, so my question to you all is, how do you test these things?

The only ideas I've had to test them so far are: A) Hooking them up to a pair of power sources (1 to plug in on the input side, 1 to hook up to the pwm cables to simulate data) and then taking a multi-meter to record voltage. or B) Pluging it in to our current test bed w/ cRIO and digital side car and then testing for continuity.

So, is there any good way for this to be tested? Nobody has any ideas on my team and those are the ideas I've posted. So, basically, help?
