I also have two adjustable current power supplies like you mentioned.
So in other words, what you're saying is reverse bias the diode across
the supply, (cathode to positive) and look for leakage as read on the
current meter? Lenny
Correct, with precaution of using a current limiting supply or
increasing the voltage slowly.

Beware using current limited supplies to test stuff, especially junctions.
You can set the current to zero, but the energy stored in the
output capacitor can zap the device. Suggest using an additional
series resistor such that the open circuit voltage can support
no more current than the device can handle.
