The barcode on the domain controller is scanned by the barcode scanner. After the information of the domain controller is input, it is placed on the clamping device 13. The clamping device 13 clamps and fixes the domain controller. The clamping and moving device 14 drives the plurality of test connectors 12 to be inserted into the interfaces of the domain controller respectively, so as to test the domain controller. After the test is completed, the clamping and moving device 14 drives the plurality of test connectors 12 to disengage from the domain controller, and the clamping device 13 releases the locking of the domain controller, completing the test of the domain controller.
