Based Testing, the Underlying Engine of Future Internet Testing - November 2011

The Future Internet will be a complex interconnection of services, applications, content and media, on which our society will become increasingly dependent. Time to market is crucial in Internet applications and hence release cycles grow ever shorter. This, coupled with the highly dynamic nature of the Future Internet will place new demands on software testing. Search–Based Testing is ideally placed to address these emerging challenges. Its techniques are highly flexible and robust to only partially observable systems. This paper presents an overview of Search–Based Testing and discusses some of the open challenges remaining to make search–based techniques applicable to the Future Internet. ...

Integration of Functional Safety in the Development Process - October 2011

The new safety standard, ISO 26262, forces automotive electronic system manufacturers to align all their development processes with safety considerations. To date, safety activities are often still undertaken quite independently from the developers’ “normal” work, however, with the consequence of safety requirements entering the development process at an advanced state causing costly additional development work. A new methodology from Berner & Mattner now enables to integrate conventional systems development closely with safety activities with the help of tools, so incorporating safety into the system design right from the beginning.

Functional Specification as a binding Contract between Principal and Manufacturer - June 2011

The development of complex control equipment as it is used in signaling and interlocking systems today calls for a structured procedure and suitable techniques for the precise description of the system requirements. One precondition for the fault-free integration of autonomously developed systems into the system as a whole is the use of precise specifications for the individual subsystems. This article presents a specification technique currently used at Berner & Mattner Systemtechnik GmbH for describing system interfaces. This model-based procedure is a suitable means for handling the challenges involved in the development of distributed systems.. ...

High-quality interface specifications with SysML modelling - March 2011

Railway network operators are increasingly facing the challenge of integrating subsystems supplied by multiple manufacturers. Currently, many interfaces lack detailed specifications that manufacturers could use for guidance. As a result, entire systems are normally ordered from a single supplier. ...

Input Domain Reduction through Irrelevant Variable Removal and its Effect on Local, Global and Hybrid Search-Based Structural Test Data Generation- February 2011

Search-Based Test Data Generation reformulates testing goals as fitness functions so that test input generation can be automated by some chosen search based optimization algorithm. The optimization algorithm searches the space of potential inputs, seeking those that are `fit for purpose', guided by the fitness function. ...

Test management for powertrains in commercial vehicles with TESTUS - January 2011

Many ECUs, many functions, many variants, many test cases, manual test execution in test vehicles and automated test stands – these are only some of the requirements a test management system has to meet in the automotive sector. Together with the powertrain part of the commercial vehicles sector of Daimler, Berner & Mattner Systemtechnik GmbH has developed a tool suite to support the test process in an optimal and complemented way. ...
