How do I test new cables for faults before connecting them

I have use a new pair of dielectric-bias cables and want to be sure they are working properly before connecting to them to my equipment.  Somewhere I read guidelines on what to test for, but I can't seem to find the info now.

I've heard that if the bias systems in these cables go bad, there can be voltage leakage into the analog signal path that can damage equipment, so I want to play it safe.

Specifically I will be testing 36V Audioquest Cheetah XLRs.  Thanks for any advice!
