4 General aspects
The co-ordinated test method as described in ISO/IEC 9646-2 [6] is used. It is possible that the entire test
suite is not applicable for all Implementations Under Test (IUTs). A test selection procedure needs to be
performed to determine the applicability of a test to a particular IUT. Such selection shall be based on the
Protocol Implementation Conformance Statement (PICS) and the Protocol Implementation eXtra
Information for Testing (PIXIT). The Abstract Test Cases (ATCs) contained in this ETS are a
comprehensive reflection of the base standards.
4.1 Test groups and subgroups
The test suite is structured following the rules defined in ISO/IEC 9646-2 [6].
4.2 Preamble
The preamble of each test case consists of the events required to bring the IUT to the appropriate initial
state. There may be alternate sequences of test steps which can be performed to initialize the IUT. These
test steps in the preamble for TC have been chosen carefully, considering the test methodology and the
other test co-ordination procedures that are available.
4.3 Test body
The test body is the sequence of steps within a test case that is essential to achieve the test purpose,
followed by the verification of the IUTs ending state. Verdicts are assigned to the possible outcomes of the
test cases.
It is important to test the observable behaviour of the IUT, which includes state transitions and Protocol
Data Unit (PDU) responses.
4.4 Postamble
At the END_MSG of the execution of a test body, the IUT may not be in an "idle state". A postamble is
then required to bring the IUT from the ending state to an "idle state".
4.5 PICS/PIXIT relationship to the ATS
There are instances when the test case flow depends on the answer to a PICS or PIXIT question. In such
instances, a Boolean expression is added to the beginning of the test body. However, it should be noted
that such conditional execution has no bearing on static conformance.

Environmental conditions:
The test laboratory may specify the normal environmental conditions applying to the laboratory to be used
for testing (e.g. temperature, humidity). The client should specify any tighter environmental conditions that
may be necessary for the correct operation of the SUT.

A.6 Ancillary protocols
This clause is to be completed by the client in conjunction with the test laboratory.
An ancillary protocol is any protocol included in the SUT other than the IUT itself, whose (correct)
operation is relied upon during the testing of the IUT.
In the following table(s), the client identifies relevant information concerning each ancillary protocol in the
SUT other than the IUT itself.
A.6.1 Message Transfer Part (MTP) protocol
The supplier of the implementation shall indicate which MTP protocol specification is implemented.
