Good evening,
Who told you that was a test? Whoever did, they were wrong.
By removing the battery cable while running, the engine should shut off. The alternator requires battery voltage to work.

Besides, by doing that you could damage other modules.
I attached the wiring diagram for you to view.
Why are you testing the alternator? Is there an issue?
