Titan is a test automation toolset supporting the complete chain of

test development, test execution and result analysis. It is based on the

standard test language TTCN-3 and thus is extremely well suited for

grey-box and black-box testing such as component, function, integra-

tion, system, acceptance, conformance and model based testing. In

addition, Titan is being used as an engine to create additional tools for

performance testing and security testing.

Titan provides a full-featured TTCN-3 open source environment with

compiler, runtime, controller, Eclipse-based and command line inter-

faces, and System Under Test (SUT) adapters for several protocols.

TTCN-3 has a proven track record for testing complex systems with a

large code base and is applicable in multiple domains.

Eclipse-based

and command line environments

Titan provides a complete Eclipse IDE and a command line; both have

been architected to work in mixed mode.

Titan’s Eclipse interface allows the development of test cases, the launch

and monitoring of test execution and analyzing test results. The

editor provides sophisticated editing, search, code completion, analysis

and quality assurance features. Test execution events and status are

shown in real-time and are logged for post-execution analysis. Test

logs can be viewed both graphically and in a textual/tabular format.

When selecting a log event, the source code line producing the event

is automatically shown.

Command line components allow the building of executable test suites

and launch test runs on demand, or automatically on an event-based

or scheduled (nightly) manner for continuous integration. They also

allow test projects, developed in the Eclipse environment, to be built

and executed from the command line.

Industrial Toolset

The Titan toolset enables teamwork in distributed teams worldwide and

can be used in workfl ows where tests are either manually developed,

generated from Models, or developed for continuous integration. Titan

provides a scalable toolset:

• Supports international specifi cations ASN.1, XSD, IDL and JSON

• Fast compilation, fast incremental re-compilation

• High performance runtime

• Detailed, confi gurable logging

• Logger plugin API and built-in loggers (JUnit, textual)

• APIs for external C/C++ functions and specifi c codecs

• API to interworking with other languages like Java, Python etc.

• Built-in codec generators for XML, ASN.1, bit-oriented

and textual protocols

• Distributed, multi-platform test execution on Linux,

Solaris and Windows platforms

Eclipse Foundation

• All-in-one solution for your testing needs

• More than ten years of development,

thousands of active users

• As an open source product licensed under

the Eclipse Public License (EPL), it avoids

vendor lock-in

• Secure investment: based on a standard

test language

• Quick development of new protocol support

and quick adaptation to protocol changes

• Well suited to both traditional V process

and agile development processes

• Allows testing at an early phase of

development: decreased cost, improved

product quality

• Faster development of tests with an

easy-to-learn intuitive test tool and language

• Increased testing productivity and test

coverage providing quicker time to market

• Multi-purpose: functional and non-functional

testing (performance, security)

• High degree of test re-usability

• A set of SUT adaptors and protocol support

are available in open source

TTCN-3 a universal standard test language

One of Titan‘s key features is its implementation of the Testing and Test Control Notation version 3 (TTCN 3) language.

TTCN-3 is an international standard, specified and published by ETSI and endorsed by ITU-T. It has been applied to a variety of

domains such as Automotive, Avionics, Finance, Healthcare, IT, Energy, Space and Telecom. It is also used in research projects

and by many universities. TTCN-3 is used by standardization bodies and consortia such as 3GPP, AUTOSAR consortium, ETSI,

MOST cooperation, OMA and the Wimax Forum to produce conformance and interoperability test standards.

TTCN-3 benefits

• Precise syntax and semantics which maximize compile time checking capabilities

• High level language and abstraction of the platform and test environment

• Rich type system, allowing the support of a wide range of protocols and API definitions

• Test data can be based directly on XSD, ASN.1, IDL and JSON (under development) specifications

• Programming language features for efficient behavior design

• Rich language features to meet testing needs

• High precision for controlling test verdict assignment and logging

• Maximum reusability due to separation of the test logic from the details of the environment:

test cases are reusable in different software development phases, platforms and test environments

• Well suited for all forms of grey-box and black-box types of testing
