Patent ID: 8185339

Claim:
A testing method for testing a plurality of devices under test, by using a DUT selection control device which is configured to select prescribed combinations from multiple combinations of the connection between the plurality of devices and a test module, based on the prescribed combinations, comprising: (a) at the DUT selection control device, acquiring information about the connection relationship between the test module and the plurality of devices under test, and, based on at least the information, generating a first combination data of devices under test that can theoretically be measured simultaneously from among the combinations of the plurality of devices under test; and (b) sequentially selecting the combinations of the plurality of devices under test to be actually measured simultaneously from the first combination data by using the DUT selection control device, and testing the plurality of devices under test in accordance with the sequence, wherein the combinations of devices under test to be actually measured simultaneously are selected in (b) in ascending order from the smallest number of devices under test that can be measured simultaneously.
