PURPOSE:To give no influence nor load at all to a host device even through a change is given to the side of a device to be tested or to the data to be tested, by transferring the expected value as well as the processing result to the host device for comparison and check. CONSTITUTION:When a host device 2 gives an instruction to a device 1 to be tested for a test action, a processing part 3 to be tested in the device 1 carries out a prescribed process to the data 4 to be tested and transfers the result of this processing to the device 2 together with the expected value 5. A comparing part 6 in the device 2 compares the received result of the processing with the expected value 5 to check whether the processing is normally carried out or not. Thus only the side of the device 1 holding the data 4 and the value 5 can cope with those changes given to the data 4 and the part 3. As a result, no load is given to the device 2. |
