A testing method for an unintended car movement protection device for an elevator, which can shorten the time required for performing the operation test, is disclosed. The testing method includes: moving a car to a position where a floor releveling operation is enabled; making an unintended car movement protection device operate for testing; enabling the floor releveling operation by an elevator control device to control the car by way of a command signal from a control device of the unintended car movement protection device while the control device of the unintended car movement protection device simulatively sets an opened door detection state in which a car door or a landing door is detected to be opened and a power cut-off command signal to be outputted to an electric motor to drive the car; performing the floor releveling operation by way of the elevator control device in such a closed door state that the car door and the landing door are being closed; and making the car in the closed door state move by unbalanced torque in accordance with the power cut-off command signal when the car lands on a releveled floor through the floor releveling operation.
