This shows a setup for benchtesting a brushless electric motor (a Turnigy brushless outrunner for illustration). The setup consists of motor, mount, esc, servo tester (or receiver), LiPo battery, and switch (optional). The wires from the 3-phase motor are connected to the esc, which is powered by a 4S1P Turnigy battery and receives its signals from the servo tester or receiver. After arming the system by completing the circuit with a Deans switch, the esc emits the correct number of beeps (4), indicating that it sees the battery. The servo tester draws its power from the built-in BEC (battery eliminater circuit), and the dial on its face can be used to change the speed of the motor. The video shows a correctly functioning motor and test system.
