Testing Software Product Lines is a very challenging task and approaches like combinatorial testing and model-based testing are frequently used to reduce the effort of testing Software Product Lines and to reuse test artifacts. In this contribution we present a tool chain realizing our MoSo-PoLiTe concept combining combinatorial and model-based testing. Our tool chain contains a pairwise configuration selection component on the basis of a feature model. This component implements an heuristic finding a minimal subset of configurations covering 100% pairwise interaction. Additionally, our tool chain allows the model-based test case generation for each configuration within this generated subset. This tool chain is based on commercial tools since it was developed within industrial cooperations. A non-commercial implementation of pairwise configuration selection is available and an integration with an Open Source model-based testing tool is under development. Copyright 2011 ACM.
Software product lines have potential to allow for mass customization of products. Unfortunately, the resulting, vast amount of possible product variants with commonalities and differences leads to new challenges in s...

Since the revision 2 of the UML, activity diagrams have acquired many new features and a completely new metamodel. UML 2 was targeted at improving semantic precision but still lacks an executable semantics as a basis for tool support and simulation. In this paper we define an executable step semantics for a subset of activity diagrams including nested interruptible activity regions, call behavior actions, and event handling. The semantics conforms to the textual description of the UML semantics but comes with a precise definition of a step including a description of the algorithm that executes a single step. The operational semantics implemented by an appropriate tool makes UML activity diagrams suitable for the specification and design of real-life complex systems from various domains.

This open access book presents the outcomes of the “Design for Future – Managed Software Evolution” priority program 1593, which was launched by the German Research Foundation (“Deutsche Forschungsgemeinschaft (DFG)”) to develop new approaches to software engineering with a specific focus on long-lived software systems. The different lifecycles of software and hardware platforms lead to interoperability problems in such systems. Instead of separating the development, adaptation and evolution of software and its platforms, as well as aspects like operation, monitoring and maintenance, they should all be integrated into one overarching process.;Accordingly, the book is split into three major parts, the first of which includes an introduction to the nature of software evolution, followed by an overview of the specific challenges and a general introduction to the case studies used in the project. The second part of the book consists of the main chapters on knowledge carrying software, and cover tacit knowledge in software evolution, continuous design decision support, model-based round-trip engineering for software product lines, performance analysis strategies, maintaining security in software evolution, learning from evolution for evolution, and formal verification of evolutionary changes. In turn, the last part of the book presents key findings and spin-offs. The individual chapters there describe various case studies, along with their benefits, deliverables and the respective lessons learned. An overview of future research topics rounds out the coverage.;The book was mainly written for scientific researchers and advanced professionals with an academic background. They will benefit from its comprehensive treatment of various topics related to problems that are now gaining in importance, given the higher costs for maintenance and evolution in comparison to the initial development, and the fact that today, most software is not developed from scratch, but as part of a c

During the commissioning phase of production systems the identification and correction of malfunctions is a tedious task mainly done manually by commissioning engineers. This task is of high importance because missed malfunctions may result in hazardous behavior during operation phase. At this point, regardless of the engineers expertise a systematic support can drastically decrease the risk of missed malfunctions. A promising systematic approach is to use engineering artifacts of the system design phase as an information source to identify unexpected behavior regarding the specification. This paper proposes such a systematic approach based on model-based testing resulting in automatic test case generation and execution which allows to support engineers with learned models representing the expected transient system behavior. Subsequently, the obtained models are used for detection of unexpected behavior during commissioning. The unexpected behavior is presented to a commissioning engineer who decides if the behavior (1) is correct and will be added to the models or (2) represents an identified system malfunction. The approach is evaluated on a demonstration plant.

Automated machines and plants are operated for some decades and undergo an everlasting evolution during this time. In this paper, we present three related open evolution challenges focusing on software evolution in the domain of automated production systems, i.e. evolution and co-evolution of (interdisciplinary) engineering models and code, quality assurance as well as variant and version management during evolution.
