Zusammenfassung:Provided is a test device including a test unit and a voltage selecting unit. The test unit applies a test current to a test pad of a test target device to detect a test response voltage, and performs DC test on the test target device on the basis of the test response voltage. The voltage selecting unit selects one of a plurality of voltages according to test modes, and applies the selected voltage to a ground voltage pad of the test target device. By selecting a voltage such that the test response voltage is not measured as a negative value, damage to the test target device during a testing process can be prevented.
