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.
6 Conformance testing system
6.1 General
The structure of communication protocol conformance testing system is shown in
6.2 Abstract test suites
According to the technical requirements of the protocol standard, write test purpose,
and form abstract test cases. The set of abstract test cases covering all the technical
requirements of the protocol standard constitutes an abstract test suite.
6.3 Static documents
Static documents include PICS and PIXIT. PICS shall be stated by the IUT provider
regarding the capabilities that IUT has implemented and the options available; PIXIT
shall include all information relating to the IUT and its test environment (other than
information given by PICS), see Table A.1, Table A.2.
6.4 Executable test suites
An executable test suite consists of executable test cases, which are implementations
of abstract test cases. According to some parameters and additional information
provided by the static document, the test laboratory can screen abstract test cases into
executable test cases and finally combine them into an executable test suite for testing.
7 Conformance testing content
7.1 Coding rules for test cases
The coding rules for communication protocol conformance testing items are shown in
7.2 Requirements for testing message time error
No. of test cases.
7.3 Other requirements
Other requirements are as follows.
a) If the operation is not specified in GB/T 27930-2015, the handling of IUT shall
meet the safety requirements;
b) During the communication process, after the current message reaches the abort
sending condition, IUT shall stop sending the message within 500 ms;
c) In the negative test, the test system will send a message that does not match the
definition of a certain message type. The “unmatched” content include message
priority, reserved bits, data page, PDU format, destination address and source
address.
