Introduction
Protocol conformance testing is a kind of functional testing, which is to test the protocol implementation under test in a certain network environment by using a series of test sequences. By comparing the similarities and differences between actual output and expected output, to determine the extent to which the implementation under test is consistent with the description standard. By protocol conformance testing, it will reduce the risk of errors when the product is running in the field.
In the realization process of the protocol, due to 1) the ambiguity of the protocol standard description and the ambiguity of understanding, 2) the programming mode and implementation method of the protocol are different, and 3) the protocol implementation has different device selection and configuration and other reasons, there are some differences between different protocol implementations, therefore, it is necessary to carry out protocol conformance testing.
Protocol conformance testing is to detect the existence of errors rather than verify that it is error-free. Relying solely on conformance testing cannot absolutely guarantee the interoperability of the application, so it shall carry out the interoperability testing on the basis of conformance testing.
Protocol conformance testing is the basis for interoperability testing. Only for products that pass the protocol conformance testing indicating that they meet the requirements of the relevant protocol standards, carrying out interoperability testing is meaningful. Protocol conformance testing does not include evaluation of the design of the protocol standard itself, nor the performance, redundancy, robustness and reliability assessment of the particular protocol implementation body.

5 Conformance testing requirements
5.1 General
This Standard is to verify whether IUT meets the requirements of GB/T 27930-2015, that is to verify the conformance between IUT and the standard in terms of protocol implementation.
5.2 Testing process
The entire testing process is shown in Figure 1. Preparation for testing includes filling in static documents, building test system, etc. PICS document and PIXIT document are done by IUT provider and test laboratory. After confirming that all devices are normally started, it may turn on PC test software and conduct subsequent test operations. After the test is completed, a test report is generated to draw the test conclusion.
