A test apparatus is provided for testing a sensorless check device of an actuator. The sensorless check device is arranged to be used by mechanically moving a check device pin from a resting position to an actuation position and then releasing the check device pin to allow it to return to a resting position urged by an elastic return mechanism. The test apparatus comprises: a piston for contact with an actuator surface associated with the check device pin; a piston spring for urging the piston toward the actuator surface, wherein the piston spring is softer than the elastic return mechanism of the check device; and an adjustment and testing mechanism.
