A test device includes an input side drive part that drives a steering shaft of a steering device, a control part that controls the input side drive part, and a position detecting part that detects an angular position of the steering shaft. The control part restricts a maximum value of a torque of the steering shaft when the angular position reaches an end-abutment position. The control part also controls driving of the steering shaft by a position control in which the angular position is used as a controlled variable and a torque control in which the torque is used as a controlled variable. The control part performs the position control when the angular position is outside a first angular range including the end-abutment position and switches the driving of the steering shaft from the position control to the torque control when the angular position reaches within the first angular range.
