4 Test Purpose generalities
4.1 Introduction
The Implementation Under Test (IUT) is always an SSF. The testing of the direct interface between SCF and SRF is
not within the scope of the present document.
Two basic scenarios are possible:
A) The SSF acts as a relay for operations exchanged between the SCF and the SRF;
B) The SSF establishes a temporary connection to an assisting SSF or handed-off SSF or directly to an SRF.
In A) the SSF is tested together with the addressed SRF, and, possibly, together with an intermediate
Assisting/Handed-off SSF. The SRF can be integrated in the SSF or not. Case A) is applicable to an SSF operating as:
1) Initiating SSF,
2) Assisting SSF, or
3) Handed-off SSF.
Individual TPs can be applicable to a true subset of the three SSF sub-functions. To handle this, Test Parameters
applicable to TP Selection are defined (see clause 4.6).
Case B) is only applicable to an SSF operating as an Initiating SSF. The operation used to connect to the SRF is
EstablishTemporaryConnection.
Configurations for cases A) and B) are defined in clause 5.
A TP is defined for one or several conformance requirements to be tested. It is expected, that each TP will result in a
test case keeping the same name, specified in the ATS.
4.2 Grouping of Test purposes
According to the two basic scenarios defined in the previous clause, the test purposes are grouped in the following 2
main groups:
a) SSF Relaying, and
b) Direct SCF-SRF operation.
Inside a main group the Test purposes are grouped by elementary procedures. A procedure groups elementary INAP
operations belonging together conceptually. The procedures are defined in clause 6.2.
4.3 Source of Test purpose definitions
The test purposes are based on the requirement documented in EN 301 931-1 [1], EN 301 931-2 [2] and
EN 301 931-3 [3].
4.4 Method used for developing Test purposes
See EN 301 933-1 [5].

4.5 Method used for Test purpose description
The table describing each TP is as shown in table 1.
Table 1: Test purpose description sample
TP name, e.g. IN3_A_BASIC_FC_BV_01

Work item no.:
Temporary work item number; to be deleted when the TPs are stable
IN2 Ref
Reference to INAP CS2 TP (optional)
Purpose: Textual phrasing of the TP to be achieved.
Requirements refs Reference to clause(s) of EN 301 931-2 [2].
For TPs related to the SRF function: also reference to clause(s) of EN 301 931-3 [3].
In the latter case the Part numbers are explicitly indicated (part 2 and/or part 3).
Selection Cond. Reference to a formal selection expression, if the TP is related to an optional INAP feature. If
the field is empty, the TP is unconditional (mandatory requirement(s)).
Preamble: Reference to a preamble or "None".
Test description Sequence of transmitted and received events and timeouts (see clause "TTCN-like
notation").
Textual description is also used, as appropriate.
Pass criteria Indication of reception (or assured non-reception) of decisive message(s) related to the TP.
Postamble: Reference to a postamble or "None".

4.5.1 Void
4.5.2 Test categories
Valid Behaviour tests (BV)
Predefined state transitions are considered as valid. The test purposes in the valid behaviour test sub group cover as far
as reasonable the verification of the normal and exceptional procedures of the various Finite State Machines (FSMs),
i.e. a valid behaviour test is a test where the message sequence and the message contents is considered as valid.
Invalid Behaviour tests (BI)
This test sub group is intended to verify that the IUT is able to react properly having received an invalid Protocol Data
Unit (PDU). An invalid PDU is defined as a syntactically incorrect message.
Inopportune Behaviour tests (BO)
This test group is intended to verify that the IUT is able to react properly in the case an inopportune protocol event
occurring. Such an event is syntactically correct but occurs when it is not expected, e.g. a correctly coded operation is
received in a wrong state (the IUT may respond by sending error UnexpectedComponentSequence).
