You can share here your knowledge on how to test a stepper motor.
If you already know, you can try the sample codes given below.

You can test your motor by using a multi tester and a LED to find the common pins.

There are two types of stepper motor, Bipolar and Unipolar stepper motor. Unipolar motor seems harder to operate than the Bipolar Stepper motor.

I searched on google, and this is what I found. Hope this answers the

using a multimeter

   Each of the two phases should have the same resistance when measured with a multimeter. When measuring the resistance across one wire from each of the two phases, the resistance should be infinite because the circuit is open. Locate the two pairs of wires that represent the two phases; both pairs of wires will have similar internal resistance.
   Connect each phase to the amplifier and ignore the polarity (+ / -), for now. You have a 50 percent chance of guessing right.
   Send a command to move the motor. If the motor rotates in the wrong direction, then switch either phase A and A- or B and B- (effectively reversing directions).

Another way, from the same website.

(w/o a multimeter)

Connect the four coil wires to the amplifier in any arbitrary pattern. Send a command to move the motor.
If the motor moves erratically or not at all, then switch one wire from phase A with one wire from phase B.
If the motor is rotating in the wrong direction, then switch either phase A and A- or B and B- (effectively reversing directions).
