PURPOSE:To detect of the presence/absence of status change of each diagnosed section and to attain easy forming of expected data, by storing the initial state of the diagnosed section and, comparing said section with the initial state stored in advance after the execution of the test processing operation. CONSTITUTION:A hardware system 1 to be diagnosed is split into blocks A-C to be diagnosed and the rest blocks D-F to be diagnosed according to the purpose of diagnosis, and the initial standard status of the blocks A-C is stored in a memory 23 in a test device 2 via an interface circuit 11. Through the operation of a keyboard 22 of the test device 2, a command is given to the blocks A-C a specified test signal is applied for the execution of the processing for test. The blocks A-C are split into diagnostic units for the execution of diagnosis and compared with the initial standard status stored in the memory 23, the status changes is detected, and through the result of detection and the comparison between discrimination flags of result of diagnosis of an external storage device 3, the normality of the blocks A-C is discriminated. |
