Internet of vehicles protocol conformance test method and system

The invention provides an Internet of Vehicles protocol conformance test method and system, and relates to the technical field of Internet of Vehicles. According to the scheme, before testing, a testing device controls a tested device and a background device to set each other as a white list device; in the test process, the test device sends a decoding test instruction to each background device or sends a coding test instruction to each tested device according to a to-be-executed test case, the background device sends a decoding test message to each tested device according to the received decoding test instruction, and the tested device sends the decoding test message to the background device according to the second white list and the decoding test message. And discriminating the received decoding test message to judge whether the decoding test message is sent by the recognizable background equipment, if so, decoding the decoding test message by the tested equipment, obtaining a decoding result of the tested
