This is a two phase test- once with the pump on the entire time, once with the pump off.

Before beginning the test, make sure the pool is filled to normal operating levels. Turn off all waterfalls, fountains, and auto-fill, and do not backwash or splash water out of the pool during the test. After everything has been turned off, wait for your water to calm and become still.
