Increasing demand for testing

The volume and interconnectivity of software

intensive systems is expanding exponentially. Theimportance of high software quality will grow and

therefore the importance of testing. Test

automation is a practical solution to this

increasing testing requirement.

A standardised test language

Testing software has specific features like a

verdict, checking data values, result-based path

decisions, time-outs and in some instances an

extreme system load. General programming

languages are in principal suitable for these tasks,

but a specific test language is of course better.

Standardising the test language has proven to be

valuable. It ensures that everyone is specifying

their test cases in the same way. Standards are

also very important for making widely applicable

tools. Test cases can then be exchanged from

one tool to another, reducing dependency on

individual vendors.

The international standard: TTCN-3

The only internationally standardised test

language is TTCN-3. The Testing and Test Control

Notation version 3 standard is published and

maintained by ETSI: the European

Telecommunication Standards Institute. While the

origins of TTCN-3 are in telecommunications, it

has been applied much more widely in the fifteen

years since its publication. It has become a

proven and mature test technology.

TTCN-3: test language for the future

TTCN-3 is supported by more and more generic

and powerful tools from multiple vendors. As it isthe only standard in test automation, it represents

the future for automated testing. Given the

growing trend towards outsourcing and off-

shoring, a standardised language is

indispensable.

Benefits and application of TTCN-3

As TTCN-3 is a generic standard it can be used

for testing all systems. Greatest benefits will be

gained when testing:

G system integrations;

G service-oriented architectures;G conformance against protocols;

G complex multi-user scenarios;

G across multiple platforms;

G without a graphical user interface.

As test automation specifications are written in

one standardised language, TTCN-3 can double

testing reuse and productivity as well as halving

long-term maintenance costs.

Why LogicaCMG?

LogicaCMG was involved from the start of TTCN-3 by being one of the contributing organisations

to ETSI. As a thought leader in testing services,

LogicaCMG was the first to recognise the

potential of TTCN-3 for all industries. From an

initial focus on telecoms, we can now support

TTCN-3 for clients from all sectors through a

dedicated competence centre.
