摘要： Provided is a test apparatus that tests a device under test, comprising a testing section that stores a program in which commands to be executed branch according to detected branching conditions and that tests the device under test by executing the program; and a log memory that stores test results of the testing section in association with command paths of the program executed to obtain the test results. The testing section sequentially changes a characteristic of a test signal supplied to the device under test, and judges pass/fail of the device under test for each characteristic of the test signal, and the log memory stores a test result of the testing section in association with a command path of the program, for each characteristic of the test signal.
