CAN/CSA-ISO/IEC-9646-3-96 (R2000)
The international community has decided to make this standard available only in
the English language version. It has been adopted as a National Standard of
Canada on this basis.
This National Standard of Canada is equivalent to International Standard
ISO/IEC 9646-3:1992.
1 Scope
This part of ISO/IEC 9646 defines an informal test notation, called the Tree
and Tabular Combined Notation (TTCN), for OSI conformance test suites, which is
independent of test methods, layers and protocols, and which reflects the
abstract testing methodology defined in ISO/IEC 9646-1 and ISO/IEC 9646-2.
It also specifies requirements and provides guidance for using TTCN in the
specification of system-independent conformance test suites for one or more OSi
standards. It specifies two forms of the notation: one, a human-readable form,
applicable to the production of conformance test suite standards for OSi
protocols; and the other, a machine-processable form, applicable to processing
within and between computer systems.
This part of ISO/IEC 9646 applies to the specification of conformance test
cases which can be expressed abstractly in terms of control and observation of
protocol data units and abstract service primitives. Nevertheless, for some
protocols, test cases may be needed which cannot be expressed in these terms.
The specification of such test cases is outside the scope of this part of
ISO/IEC 9646, although those test cases may need to be included in a
conformance test suite standard.
NOTE 1 - For example, some static conformance requirements related to an
application service may require testing techniques which are specific to that
particular application.
This part of ISO/IEC 9646 specifies requirements on what a test suite standard
may specify about a conforming realization of the test suite, including the
operational semantics of TTCN test suites.
NOTE 2 - ISO/IEC 9646-4 specifies requirements concerning test realization
including ETS derivation.
This part of ISO/IEC 9646 applies to the specification of conformance test
suites for OSI protocols in OSI layers 2 to 7, specifically including Abstract
Syntax Notation One (ASN.1) based protocols. The following are outside the
scope of this part of ISO/IEC 9646:
a) the specification of conformance test suites for multi-peer or
Physical layer protocols;
b) the relationship between TTCN and formal description techniques;
c) the specification of test cases in which more than one behaviour
description is to be run concurrently;
NOTE 3 - Use of parallel trees and synchronization between them is to
be covered by a future amendment to this part of ISO/IEC 9646.
d) the means of realization of executable test suites (ETS) from
abstract test suites.
