If your cable includes a shield wire (ground line) which runs from shell to shell and you wish to test that wire for shorts to any other conductors, your cable shells must become active test points. Cirris offers adapters with either pogo pins or a wire with aligator clip soldered to the shell as a way to test this type of cable. The pogo pins (or wire with an aligator clip) are tied to the active test circuit of the adapter. The photos below illustrate the idea.

2 pogo pins per adapter make contact (as well as the metal shell itself) from adapter to shell to insure adequate contact for testing.
