Summary:Provided are a test device and a test method with which it is possible to perform far-field measurement of RF characteristics or RRM characteristics at low cost. A test device to measure transmission properties or reception properties of a test object having an antenna under test, the test device comprising: an anechoic box; a plurality of test antennas configured to transmit or receive a radio signal to or from the antenna under test; a posture changeable mechanism configured to change a posture of the test object arranged in a quiet zone (QZ) in the internal space; a measurement device configured to measure the transmission properties or the reception properties of the test object, using the test antenna with respect to the test object whose posture is changed by the posture changeable mechanism; and a reflector on which the radio signal is reflected, wherein the plurality of test antennas include a reflection-type test antenna that transmits or receives the radio signal to or from the antenna under test th
