You look at them and see if they are cracked/broken.

have the hood open, apply E-brake, either you or friend watch them, and other person puts it in gear and lets out on the clutch a bit, enough to make the engine lurch, forwards and backwards. dont over do it, too much may damage the clutch.

use a flashlight to see any cracks or separation of rubber.
