RE: Testing Inductors and Capacitors
I worked for a manuf. that made large inductors. We built a test fixture with caps, variac, transformer, a CT, and motor starter. We'd connect the inductor, charge the caps to twice the inductor voltage rating, and close the starter. This put the inductor in a "tank" circuit. We used the CT to capture the resulting waveform on a scope. From the frequency we could determine the inductance (since the capacitance was already known). The waveform shape would tell us if there were any other problems. For current handling, we'd hook the inductor to an SCR bridge and run it at rated current until the temp stabilized.

BK Precision makes one, the model 878 LCR meter.
Obviously, insulation resistance tests to ground are always applicable for both capacitors and inductors.
