WCT: A Wrapper for Component Testing [chapter]

Antonia Bertolino, Andrea Polini
2003 Lecture Notes in Computer Science  
To address such problem, we propose the WCT component, a generic test wrapper that dynamically adapts the component interfaces, making the test execution independent from any specific component implementation  ...  Within component based (CB) software development, testing becomes a crucial activity for interoperability validation, but enabling test execution over an externally acquired component is difficult and  ...  WCT, a Wrapper for Testing Purposes In this section we introduce the structure of the WCT, a wrapper to be integrated in a CB testing platform, to permit the easy reconfiguration of the subsystem under  ...

Automating the runtime performance evaluation of simulation algorithms

Roland Ewald, Adelinde M. Uhrmacher
2009 Proceedings of the 2009 Winter Simulation Conference (WSC)  
This problem is aggravated when it comes to comparing many alternative implementations for a multitude of benchmark model setups.  ...  Desirable benchmark model properties are motivated, and the quasi-steady state property of such models is exploited for simulation end time calibration, a simple technique to save computational effort  ...  If a simulator exhibits an execution time t wct > t wct max for a currentSimEndTime > t sim min , a watchdog procedure outside the main calibration algorithm stops testing the suitability of currentSimEndTime  ...

A framework for component deployment testing

A. Bertolino, A. Polini
2003 25th International Conference on Software Engineering, 2003. Proceedings.  
CDT provides the customer with both a technique to early specify a deployment test suite and an environment for running and reusing the specified tests on any component implementation.  ...  To this purpose, we propose the CDT framework for Component Deployment Testing.  ...  In order to simplify the integration of more virtual components, as well as the integration of more real components to form a virtual one, we have presented in [3] a particular wrapper named WCT (Wrapper  ...

Avoiding timing channels in fixed-priority schedulers

Marcus Völp, Claude-Joachim Hamann, Hermann Härtig
2008 Proceedings of the 2008 ACM symposium on Information, computer and communications security - ASIACCS '08  
We describe the modified scheduler, provide a mechanical PVS-based proof of noninterference and show how common admission algorithms can be reused to give real-time guarantees for this modified scheduler  ...  This modification is rather simple: we compute at admission time a static predicate that states whether a thread may possibly leak information; if such a thread blocks we switch to the idle thread instead  ...  We further thank Intel Corp. for their support. This work is in part funded by the European Commission through PASR grant 004700.  ...

Automating Knowledge Discovery Workflow Composition Through Ontology-Based Planning

Monika Zakova, Petr Kremen, Filip Zelezny, Nada Lavrac
2011 IEEE Transactions on Automation Science and Engineering  
A formal capture of this knowledge is thus needed, to serve as a basis for intelligent computational support of workflow composition.  ...  A procedure for converting algorithm descriptions into PDDL was developed. The second directly queries the ontology using a reasoner.  ...  New algorithms can be easily added to the RDM Engine by developing a wrapper for the particular algorithm and possibly also an API for accessing the results in case the particular result type is not yet  ...
