A testing apparatus which, when resuming a test after interruption, makes it possible to determine whether or not an apparatus to be tested is the one for which the test has been interrupted. A controller acquires identification information for identifying the apparatus to be tested. The controller carries out a test comprised of a plurality of testing items to be executed on the apparatus to be tested. When the test is interrupted, a recording section is operable to record resuming information for carrying out the test on unexecuted testing items among the plurality of testing items, and the acquired identification information.
