TTCN Test Solutions – and Beyond

TTCN-3 based Quality Assurance, Mobile Radio Conformance Testing, Embedded TTCN-3 Technology Devoteam’s TTCN-3 Toolbox – the TTCN-3 power engine in world’s leading Mobile Radio Conformance Test Systems

Get in touch

For decades Devoteam is one of the world’s leading suppliers for TTCN-3 test technology tools.

TTCN-3, the Testing and Test Control Notation, developed and standardized by ETSI, the European Telecommunications Standards Institute (,, ) is nowadays the state-of-the-art test specification platform for mobile radio conformance tests specified by 3GPP RAN5 (up to LTE, 5G and beyond, see: ), for Internet of Things (IoT) tests, OneM2M tests (, etc.

Devoteam’s TTCN-3 Toolbox is the TTCN-3 power engine in world’s leading mobile radio conformance test systems running test cases at a high execution speed.

The TTCN-3 Toolbox comprises a TTCN-3 Compiler including an ASN.1 Compiler, an XSD Compiler and several CODECs. It supports the ETSI ES 201 873 TTCN-3 Standard series and can therefore be easily integrated in TTCN-3 tool chains or embedded in customer test systems

Beyond TTCN Devoteam’s Test Solutions are customized to testing needs of our customers to reduce business risks and ensure both higher stability and business continuity. By using Devoteam’s Software Test Management, Software Test Automation tools and methodologies, defects can be detected earlier and fixed at any stage of the software lifecycle.

Customer Benefits

With the know-how of our experts, we can provide our customers with innovative and leading best practices for testing with TTCN-3, such as TTCN-3 test suite development, TTCN-3 based test solution development, system integration, system and service testing, and a wide range of other testing services.

Cut back of customers testing investments

through highly standardized test component interfaces

Faster test system development

to ensure higher quality and reliability and shorter time to market

Highly automated regression testing capabilitiess.

to increase client’s product quality by leveraging available TTCN-3 test suites for UMTS, LTE, 5G, and beyond and for the upcoming Smart Grid, M2M, and Internet of Things technologies.

Improved testing productivity 

through the use of standardized TTCN-3 technology components (test language, codec, logging, test campaign management, distributed test run support) by using TTCN-3 as a platform-independent technology on Windows, Linux, etc. and by sharing test suite development and approval across teams, organizations and companies.
