Basics and application trends for the testing and test control notation TTCN-3

Strong dependencies exist between innovations - standards and markets: Innovations influence standards and markets. Standards have impacts on markets and often are the basis for innovations. The market solutions are combined into standards. And new markets could be understood as an innovation. The testing technology TTCN-3 appears in all of these aspects. It is an established standard widely used in industry; it includes and brings up innovative concepts. This technology is evolving due to increasing industrial requirements and new research ideas. The roots of today's "Testing and Test Control Notation" (TTCN-3) started in the 80s. New tool and industrial test suite standards appeared shortly after its first publication by ISO. Initially used in telecommunication, today TTCN-3 i s applied for testing complex software in nearly all industrial domains. In particular, new application areas are automotive, medical, aerospace, and finance systems. TTCN-3 is a success story. Engineering departments of tool manufacturers and research institutes are using TTCN-3 as a target notation in the context of model-based testing. This year the European Standardization Institute (ETSI) has published several innovations that provide a standardized basis to the industry for innovative testing. Substantial work has been undertaken for "embedded TTCN-3" that includes real-time aspects and continuous systems. In the case of TTCN-3 the standardization bodies succeeded to create an engine for innovation and new markets. The tutorial provides the understanding of basic concepts t ogether with a presentation of latest concepts and new directions for the test technology TTCN-3

Security Testing Approaches - for Research, Industry and Standardization: Presentation held at International Standard Conference on Trustworthy Computing and Services (ISCTCS), 29.-30. November 2013, Beijing, China

Recently, in the Security testing domain a lot of knowledge has been collected from a significant amount of research. The presentation provides an introduction to advanced security testing methods and techniques in the context of European research and standardization projects. This includes numerous guidelines and best practices that have been identified and are applied in the context of industrial case studies. In particular it addresses risk modeling, security test pattern, functional security tests as well as fuzz testing, as important contributions to systematic, automatized test approaches in research, industry and standardization

Security testing approaches in industry and standardization

Security and model-based testing are no new topics but still under development and of high interest. In particular, their combination is still a challenge for academic work and industrial applications. Systematic and automated security testing include e.g. security functional testing, Model-based fuzzing, Risk-oriented testing and the usage of security test pattern. National and international standardization committees provide significant efforts by their working groups in the context of security testing. They cover fundamental frameworks but also detailed test specifications for concrete technologies. The range of activities is very large and includes classical concepts from security evaluation using common criteria (CCRA) but also European activities from ETSI addressing TVRA. The cont ribution gives an overview about important standardization taxonomies and activities as well as sample innovative industrial case studies, including tools and techniques that have been selected in the European ITEA project DIAMONDS

The UML 2.0 Testing Profile and its Relation to TTCN-3

UML models focus primarily on the definition of system structure and behaviour, but provide only limited means for describing test objectives and test procedures. However, with the approach towards system engineering with automated code generation, the need for solid conformance testing has increased. In June 2001, an OMG Request For Proposal (RFP) on an UML2.0 Testing Profile (UTP) has been initiated. This RFP solicits proposals for a UML2.0 profile, which enables the specification of tests for structural and behavioural aspects of computational UML models, and which is capable to inter-operate with existing test technologies for black box testing. This paper discusses different approaches for testing with UML and discusses the ongoing work of the Testing Profile. Special emphasize is laid on the mapping of UML2.0 testing concepts to the standardized Testing and Test Control Notation (TTCN-3)

Architecture-driven testing using TTCN-3

Success coming with MBT highly depends on the availability of the underlying system specification and the acceptance of related tools. In industrial practice is has been found very often that the system specification could not be fully completed and need to be restricted to selected parts. The Architecture-driven test approach (ADT) considers a system specification that is decomposed following different viewpoint that allows an easier understanding due to various abstractions. In this contribution we discuss how we extend our work that has been introduced earlier on ADT in order to execute ADT-based test descriptions against real systems in the context of the automotive domain
