The present invention provides an engine testing apparatus capable of accurately conducting a simulation of a vehicle and includes a dynamometer connected to an output section of an engine under test, a dynamo controller for controlling rotation of the dynamometer, and an actuator for controlling a throttle opening degree of the engine. The dynamo controller and the actuator are controlled to adjust an output of the engine under test, wherein a constant speed driving slip ratio (Sa) in a constant speed running state in a target vehicle speed pattern, an acceleration driving slip ratio (Sb) in an acceleration running state, and a deceleration driving slip ratio (Sc) in a deceleration running state are previously computed as data for correcting tire slippage of the actual running vehicle.
