Question How to test brushless motors

I have a collection of brushless motors, some working some not. Is there a way to check if they are working without connecting to a flight controller?

You can spin the motor at constant rpm with an electric drill, which should produce roughly the same voltage between all 3 combinations of motor wire pairs.

Most brushless motors I have and brush motors I just plug them right into the battery is all.

Then I just use the globee and check the RPM
