Testing the principles at the heart of the interoperable world
By Philip Makedonski, Vice Chair, ETSI TC MTS (Technical Committee Methods for Testing & Specifi cation) S
tandards are essential enablers for interoperability in an increasingly connected world. Standards allow devices – whether a
smartphone, a personal-fitness tracker or a connected vehicle – to interact with each other and their surrounding environment. As such, testing is essential to ensure that equipment and systems produced to these standards work consistently. Recognised by the European Union
as a European Standards Organization, ETSI produces technical standards for Information and Communications Technologies (ICT) enabled products, systems, services and applications that are widely used across all sectors of industry and society, both in Europe and farther afield. The standards created by ETSI allow
enterprises to be more competitive, accelerating time to market for the development of new products and ensuring they address the broadest possible market.
ETSI also manages the TDL Open Source Project – a platform for exploring new language features and application domains and for ensuring the consistency of TDL standards
Testing languages T e centrepiece of ETSI’s methodology for test specifi cation development – including test purposes, descriptions and cases – is its own testing language, the TTCN-3 (Testing and Test Control Notation version 3), widely used to defi ne conformance suites in a range of applications, from mobile broadband to

automotive. TTCN-3 is complemented by TDL (test description language), which fi lls the gap between what needs to be tested and the concrete coding of executable tests using existing test specifi cation languages. In parallel with oversight of the
development and maintenance of these testing languages, ETSI also manages the associated TDL Open Source Project, which provides a platform for exploring new language features and application domains, and in turn ensuring the consistency of TDL standards and accelerating adoption of the language by industry.
RESTful API testing More and more telecommunication networks, systems and digital interfaces are being implemented as and managed by soſt ware-based solutions rather than physical hardware. T is fundamental shiſt also means that testing practices are themselves evolving. A well-known and widely-adopted
design methodology is taking centre- stage, which uses the Representational
