Manny,

I've tested dozens and dozens of stepper motors over the years, and I've always had to use a power supply and a stepper driver to thoroughly test a motor.

You can do some very simple tests, like reading the resistance of each coil with a meter. You can turn the motors by hand and listen for binding, but the very nature of a stepper motor means that the motor will jerk between magnet positions.

I'm afraid that you'll have to actually run the motors before you can verify that they work properly.
