PROBLEM TO BE SOLVED: To accurately measure current consumption of a device under test. SOLUTION: This test apparatus for testing a device under test includes a voltage supplying section which supplies a voltage to the device under test through a wire, a first capacitor which is arranged between the wire and a common potential in series, a current detecting section which detects a current flowing through the wire at a location closer to the device under test than the first capacitor is, an integrating section which outputs an integration value obtained by integrating a difference between the current detected by the current detecting section and a predetermined reference current, and a determining section which determines whether the device under test is a pass or a failure based on the integration value.
