Abstract

The present document provides the specification of the runtime interface for TTCN-3 test system implementations. The
TTCN-3 Runtime Interface provides a standardized adaptation for timing and communication of a test system to a
particular processing platform and the system under test, respectively. The present document defines the interface as a
set of operations independent of target language.
The interface is defined to be compatible with the TTCN-3 standard (see ETSI ES 201 873-1 [2]). The present
document uses the CORBA Interface Definition Language (IDL) to specify the TRI completely. Clauses 6, 7 and 8
present language mappings for this abstract specification to the target languages JavaTM, ANSI C, and C++. A summary
of the IDL based interface specification is provided in annex A.
NOTE: JavaTM is the trade name of a programming language developed by Oracle Corporation. This information
is given for the convenience of users of the present document and does not constitute an endorsement by
ETSI of the programming language named. Equivalent programming languages may be used if they can
be shown to lead to the same results.

Overview

SIST ES 201 873-5 V4.9.1:2022 specifies the TTCN-3 Runtime Interface (TRI), an essential element for implementing test systems using the Testing and Test Control Notation version 3 (TTCN-3). Developed by the Slovenian Institute for Standardization (SIST), this standard aligns with ETSI ES 201 873-5 and provides a platform-independent, standardized adaptation layer between TTCN-3-based test systems, underlying processing platforms, and the systems under test (SUT).

The TRI defines a comprehensive set of operations governing timing and communication for TTCN-3 test execution, ensuring consistent interoperability and adaptability across various implementation environments. The interface is abstract, language-independent, and is formally specified using CORBA Interface Definition Language (IDL), with detailed mappings for Java, ANSI C, C++, and C# included.

Key Topics

  • TTCN-3 Runtime Interface (TRI): Specifies operations needed for communicating and synchronizing between the test system and the SUT/platform.
  • Language Independence: Abstract interface defined using IDL allows for mappings to multiple programming languages, ensuring flexibility and portability.
  • Standardized Communication and Timing: Encompasses interfaces for message passing, procedure calls, timer handling, and error reporting.
  • Platform and System Adaptation: Facilitates the adaptation of TTCN-3 test logic to diverse processing environments and platforms.
  • Test System Structure: Covers entities such as Test Management and Control (TMC), TTCN-3 Executable (TE), SUT Adapter (SA), and Platform Adapter (PA).
  • Error Handling and Reporting: Defines standard mechanisms for conveying errors and managing exceptions during test execution.
  • Language Mappings: Sections detail standardized mappings for Java, ANSI C, C++, and C# to enable implementation on various platforms.

Applications

The TTCN-3 Runtime Interface plays a critical role in automated conformance and interoperability testing across different industries:

  • Telecommunications: Used for protocol and system testing within communication networks, such as 3GPP and IMS platforms.
  • Software Quality Assurance: Supports verification of system behavior and robustness by providing a rigorous, automated test execution environment.
  • Embedded Systems and IoT: Ensures adaptability by allowing TTCN-3 test suites to be executed across heterogeneous hardware environments.
  • Network Equipment Testing: Enables manufacturers to validate their devices against international standards consistently.
  • Research and Development: Facilitates development of new communications technologies by providing a standardized, repeatable testing framework.

By providing a unified runtime interface, organizations benefit from reduced integration effort, improved test portability, quicker onboarding of new testing platforms, and a future-proof approach for evolving technology demands.

Related Standards

The SIST ES 201 873-5 V4.9.1:2022 document is part of the broader TTCN-3 and testing standards ecosystem. Key related documents include:

  • ETSI ES 201 873-1: The core TTCN-3 language specification that defines the syntax and semantics of TTCN-3.
  • SIST ES 201 873 series: Covers additional TTCN-3 parts, including test system architecture, logging, and documentation.
  • ISO/IEC 9646: Reference for conformance testing methodologies and framework.
  • ETSI MTS standards: Methods for Testing and Specification suite, covering methodologies, frameworks, and supplementary TTCN-3 components.

For implementers and users of TTCN-3-based test systems, adherence to the TTCN-3 Runtime Interface standard ensures reliable, consistent, and interoperable test execution across diverse platforms and application domains.

Introduction
The present document consists of two distinct parts, the first part describing the structure of a TTCN-3 test system
implementation and the second part presenting the TTCN-3 Runtime Interface specification.
The first part introduces the decomposition of a TTCN-3 test system into four main entities: Test Management (TM),
TTCN-3 Executable (TE), SUT Adaptor (SA), and Platform Adaptor (PA). In addition, the interaction between these

Foreword
This ETSI Standard (ES) has been produced by ETSI Technical Committee Methods for Testing and Specification
(MTS).
The present document is part 5 of a multi-part deliverable. Full details of the entire series can be found in part 1 [2].
Modal verbs terminology
In the present document "shall", "shall not", "should", "should not", "may", "need not", "will", "will not", "can" and
"cannot" are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of
provisions).
"must" and "must not" are NOT allowed in ETSI deliverables except when used in direct citation.
Introduction
The present document consists of two distinct parts, the first part describing the structure of a TTCN-3 test system
implementation and the second part presenting the TTCN-3 Runtime Interface specification.
The first part introduces the decomposition of a TTCN-3 test system into four main entities: Test Management (TM),
TTCN-3 Executable (TE), SUT Adaptor (SA), and Platform Adaptor (PA). In addition, the interaction between these
entities, i.e. the corresponding interfaces, is defined.
The second part of the present document specifies the TTCN-3 Runtime Interface (TRI). T
