Provided is a test apparatus that tests a DUT, which includes a driver that outputs a test signal to the DUT, a first transmission path that electrically connects the driver and the DUT, a first FET switch provided on the first transmission path to connect or disconnect the driver and the DUT to or from each other, and a capacitance compensator that detects an output signal from the DUT, and charges or discharges a capacitive component of the first FET switch based on the detected output signal.
