PPROBLEM TO BE SOLVED: To execute a connection test of channel device (CH) and peripheral processor (PCU) without using an expensive pseudo input and output processor (PIO) while improving the test efficiency and the coverage. PSOLUTION: This test device comprises a CH function achievement part achieving CH function and a CPU function achievement part achieving PCU function. (1) The CH function achievement part is operated in a non-test mode, and (2) when a switching instruction to a test mode is received, the CPU function achievement part is operated instead of the CH function achievement part.
