I would like to get some clear idea on how to test components of what
I build.

Say, just a servo: can I test it by connecting a small DC power supply
to + and - cables and gradually increasing voltage? I should see it
run, right?

Yes, based on it having two leads, it's just a DC motor.


Or, a servo with amplifier: give amplifier power and apply small
voltage to the +/-10v command input. Then it should move the servo
motor. Right?

The AMC amps have an offset adjustment on the command input that make
it easy to run the motor without an external command.
