SIP Signaling Tester

Test Harness & Test Suite for the Validation of SIP Implementations.

SIP Conformance Test Architecture

Overview

The SIP Signaling Tester is a test environment for the SIP signaling specification as defined by the IETF standards. It is a SAFIRE based test harness able to run pre-defined ACATS test scenarios against SIP test objects in a controlled & deterministic manner.

The SAFIRE graphical editor allows new scenarios to be created or existing scenarios to be modified using the SIP interface library (API), which defines the SIP messages and parameters. The test harness includes a SIP protocol analyzer for on-line capture and decode of the signaling in real-time both during tests and as a stand-alone tracer for live systems.

The SIP Signaling Tester is suitable for conformance tests, functional tests, factory tests & acceptance tests.

Key Features

• Fully integrated, complete test environment for SIP
• ISO conformant test scenarios giving framework coverage of SIP
• Graphical development environment & libraries for creating new SIP tests
• Compatible with ACATS SIP Professional Test Suite (not included)
• Expandable for SIGTRAN, H.323, MGCP, Megaco, ISUP-SIP interworking
• SIP Reference Test Object

Description

The SIP Signaling Tester was designed to be a complete solution for SIP signaling test requirements.  It has the key components:

• SIP Test Harness including codec & IP stack
• ACATS SIP Framework Test Suite
• SIP Interface Library
• SIP Protocol Analyzer

The SIP test harness uses the powerful SAFIRE environment to provide advanced features like

• Graphical editing (flow diagram representation)
• Automated execution of test campaigns
• Slow motion replay with synchronized trace & breakpoints
• Test reports with statistics (also HTML)
• Real-time, high performance protocol analysis

Using the SIP Signaling Tester, test objects can be accurately, reliably and comfortably validated for compliance with IETF standard RFC 3261. It is suitable for manufacturers, network operators and service providers to address all stages of the development cycle, regression testing through to type approval, acceptance testing & certification (note:  requirements may be country/organization specific).

The ACATS SIP Framework Test Suite includes test scenarios for the validation of terminal equipment by simulating the controlled interaction with other SIP entities such as

• User Agent (Client or Server)
• Registrar
• Proxy (Outbound)
• Redirect Server IUTs.

SAFIRE Editor Sample

The framework test suite contains a selection of important scenarios, which can be used to confirm the basic functionality of a SIP test object. They are also an excellent basis for customization and enhancement according to specific needs.

An upgrade is available for the ACATS SIP Professional Test Suite, which offers extensive coverage of the SIP signaling test requirements.

SIP Reference Test Object

For reference a virtual test harness is included, that allows test scenarios to be run off-line against a software-only test object under controlled conditions.  The test harness uses a software bus to replace the physical connection and an accurate software model as the test object.  Normally fully automated execution of tests is possible, but in some specific cases the test object allows/requires user interaction during the tests.
