Testing apparatus and testing method

Provided is test apparatus with higher testing efficiency, including: plurality of pattern generating sections generating test pattern to supply to devices under test; group control section controlling group of pattern generating sections out of the pattern generating sections, and generating control signal upon receiving signal output from any pattern generating section controlled; range information storage section storing range information indicating range of pattern generating sections, out of the pattern generating sections, that serve to test one independent device under test; and comprehensive control section receiving the control signal from the group control section, identifying any pattern generating section that supplies the test pattern to the same device under test as that to which the pattern generating section having output the signal supplies the test pattern based on the range information, and in response to the control signal, controlling any other group control section that controls the identified pattern generating section.
