Specifically, after the device to be tested is installed on the test fixture, the test intermediate agent acquires the ID of the device to be tested and sends a discover data packet containing the ID to each IP address in the network;
after the device to be tested, namely the router, is installed on a test fixture, the ID number of the device is scanned manually through a scanner, and the scanner transmits the ID to a test intermediate agent; certainly, in practical application, the ID of the device to be tested may be obtained in other manners, and the current testing manner supports both manual scanning and automatic testing by automatically reading the device ID by an intermediate agent, which is not limited too much.
When the device to be tested matched with the ID responds to the discover data packet, the testing intermediate agent receives response data sent by the device to be tested, wherein the response data comprises a target IP address and the ID of the device to be tested; the testing intermediate agent sends the ID and the target IP address of the device to be tested to a server; and the server adds the ID and the target IP address into the test instruction to carry out the step 1.
In this embodiment, the testing method meets the design requirement of high cohesion and low coupling, all the test contents are stored in the server, specifically, the server is preset with the test contents corresponding to each ID, and the test instruction includes the test contents. When equipment with a new model needs to be tested, the test content is only required to be updated at the server side, and the test intermediate agent does not need to be changed.
