Disclosed is an electronic parking brake (EPB) system including an EPB actuator, having a motor, to operate the motor to generate parking brake force with respect to a wheel. The EPB system includes a test device connected to the EPB actuator to test a function, performance, or breakdown of the EPB actuator. The test device includes a connection cable provided at one side of a main body of the test device such that the connection cable is electrically connected to the EPB actuator, a diagnosis switch provided at a front of the main body to allow a user to input a diagnosis command for the EPB actuator, a diagnosis lamp provided at the front of the main body to indicate whether the EPB actuator has broken down, and a battery mounted in the main body to supply power for diagnosis to test the EPB actuator. When the diagnosis switch is input, the test device supplies power from the battery to the EPB actuator to diagnose whether the EPB actuator is abnormal and the diagnosis lamp is turned on or off based on the diagnosis result.
