To provide a canalization confirmation testing device or the like, capable of contributing for the easy and quick execution of a canalization confirmation test of each port of a switch which becomes a test object for a person who does not have a specialized knowledge.SOLUTION: A canalization confirmation testing device performs a canalization confirmation test of a test object switch using a connection switch. In a state where the connection switch and the test object switch are connected via a first cable, the canalization confirmation testing device and the connection switch are connected via a second cable, the canalization confirmation testing device and the test object switch is connected via a third cable, setting information and port status information are acquired from the test object switch via the third cable, test setting information is formed on the basis of the acquired setting information and the port status information, the test setting information is stored in the connection switch via the second cable, the connection switch is controlled via the second cable from the canalization confirmation testing device, and the canalization confirmation test about a port of the test object switch is executed via the first cable from the connection switch.SELECTED DRAWING: Figure 5
