Tip: if you have two identical inductors, you can connect them in series, using a bypassed (low impedance, voltage source) supply to set the bias current. Then the middle node is simply the impedance of two inductors in parallel, each going to ground (since the bias supply is at AC ground). Any impedance measurement method can be used, with a coupling capacitor if necessary to remove the last bit of DC offset. For example, resonating the inductor with a capacitor, and measuring the impedance peak (peak frequency and capacitance gives inductance; amplitude ratio or bandwidth gives resistance or Q).

The complement of this, is quite commonly used in RF circuitry: varactor diodes are commonly available in a series-opposed configuration, so the middle tap can be biased to set capacitance, while the end terminals are tied with some impedance (an oscillator or tuned amplifier). Also works equally nicely to measure, for example, type 2 ceramic dielectric saturation.
