This video shows how to test your stepper motor working . A simple test with led without using any multimeter .
Connect led across any two wires and twist the motor shaft. Thanks for watching

CONCEPT: "In a Stepper motor or any motor (DC) Electric energy is converted into Mechanical energy (rotation of motor shaft). Hence if we are providing mechanical Across Stepper motor Shaft then It must again further generate electric energy . This is called law of conservation of energy "Energy cant be created or destroyed it just transforms from one form to another" Or 1st law of thermodynamics , hence this results in glowing of led  connected across terminals of Stepper motor shaft when it is provided with mechanical energy"
