How can I test my fan?

I'm not sure my fan i put into the car actually turns on. I know that it works and hot damn does it ever push a lot of air.

How do i test to see that the system is working properly to trip the fan on?
I've left the car running for ages before and it never came on...
didn't even get close to over heating though sooo?
and when the needle has risen from things like belts breaking the fan didn't come on either (because the head was hot and the thermo switch at the bottom on the rad was not)

drive hard, and I mean really hard, get the temp to come up(beyond what you see normally) and pop the hood.

idling my car wont get very hot either...
