ETSI Approach to Testing
One main aim of standardization is to enable interoperability in a
multi-vendor, multi-network, multi-service environment. Many ETSI Technical
Bodies rely on the following three pillars of good practice to help realise
This website gives an overview of these three pillars and information on how
they can be applied to your own standards development.
ETSI brochure Interoperability Best Practices gives more information on
Standards need to be designed for interoperability from the very beginning.
Well-specified, unambiguous requirements can contribute to the overall technical
quality of a standard, thus minimizing the potential of non-interoperable
The correct use of the
ETSI drafting rules, the application of good protocol specification practices,
the use of specification languages all go towards making a well-engineered standard.
The ETSI Guide to Writing World Class Standards gives guidance on how to
achieve world class quality of ETSI deliverables.
Most standards are complex documents (or sets of documents) and, even when
great care has been taken in the drafting stages, ambiguities, incompleteness
and even errors will still occur.
Feedback from validation activities is a very good way to remove these inconsistencies
and improve the overall quality of the documentation.
Validation should be interleaved with the evolution of the standard itself.
The CTI works with the ETSI Technical Bodies to set up validation programs, such as
interoperability events or Plugtests, to improve the quality of standards in an
efficient and pragmatic way.
See how to plan and organize a Plugtest to validate your standards.
The development of standardized test specifications is an integral part of
the ETSI strategy for ensuring interoperability. Much of the industry we serve
recognizes, and places great importance in, the ability to test products and
services in a standardized manner. For example, the use of ETSI conformance test
specifications in the Global Certification Forum (GCF) certification of GSM and
UMTS™ handsets guarantees interoperability of these terminals over the air
interface. Read more...
Reflecting the principle: test the components first, then test the system,
ETSI focuses on the development of two types of test specifications:
Like validation, the development of test specifications should be interleaved
with the evolution of the standard itself. The CTI works with the ETSI Technical
Bodies to set up test frameworks and to develop test specifications which, like
any other standards, can be freely used by industry. However, the actual testing
of a product is, for the most part, outside ETSI's responsibilities.
