Gonzales-Sanchez, A. (author), Piel, E.A.B. (author), Gross, H.G. (author), Van Gemund, A.J.C. (author)Runtime testing is emerging as the solution for the integration and assessment of highly dynamic, high availability software systems where traditional development-time integration testing cannot be performed. A prerequisite for runtime testing is the knowledge about to which extent the system can be tested safely while it is operational, i.e.,...journal article 2011

Gonzalez-Sanchez, A. (author), Abreu, R. (author), Gross, H. (author), Van Gemund, A. (author)When failures occur during software testing, automated software fault localization helps to diagnose their root causes and identify the defective components of a program to support debugging. Diagnosis is carried out by selecting test cases in such way that their pass or fail information will narrow down the set of fault candidates, and,...report 2010

Gonzalez-Sanchez, A. (author), Abreu, R. (author), Gross, H. (author), Van Gemund, A. (author)In development processes with high code production rates testing typically triggers fault diagnosis to localize the detected failures. However, current test prioritization algorithms are tuned for failure detection rate rather than diagnostic information. Consequently, unnecessary diagnostic effort might be spent to localize the faults. We...report 2010

Zutt, J. (author), Van Gemund, A.J.C. (author), De Weerdt, M.M. (author), Witteveen, C. (author)An important problem in transportation is how to ensure efficient operational route planning when several vehicles share a common road infrastructure with limited capacity. Examples of such a problem are route planning for automated guided vehicles in a terminal and route planning for aircraft taxiing at airports. Maintaining efficiency in such...book chapter 2010

Gonzalez, A. (author), Piel, E.A.B. (author), Gross, H.G. (author), Van Gemund, A.J.C. (author)Paper submitted for review at QSIC'10 Test prioritization techniques select test cases that maximize the confidence on the correctness of the system when the resources for quality assurance (QA) are limited. In the event of a test failing, the fault at the root of the failure has to be localized, adding an extra debugging cost that has to be...report 2009

Abreu, R.F. (author), Zoeteweij, P. (author), Van Gemund, A.J.C. (author)This technical report is meant to report our findings and ideas with respect to spectrum-based fault localization and modelbased diagnosis. In the following we want to introduce and compare model-based diagnosis (MBD), spectrum-based fault localization (SFL) and our contributions using 3-inverters as a running example (which is simple, yet...report 2008

(author)Preprint of paper published in: ENASE 2008 - Proceedings of the 3rd International Conference on Evaluation of Novel Approaches to Software Engineering, 4-7 May 2008 Fault screeners are simple software (or hardware) constructs that detect variable value errors based on unary invariant checking. In this paper we evaluate and compare the...report 2008

Van Gemund, A.J.C. (author), Abreu, R.F. (author), Zoeteweij, P. (author)In this working report we outline how to determine the intermittency parameters gj from the activity matrix A (context: DX’08 paper Abreu, Zoeteweij, Van Gemund). We start with the single fault (SF) case and show that averaging over the error vector e is the exact way. We also show that in this way the probability of obtaining exactly this e...report 2008

Abreu, R. (author), Zoeteweij, P. (author), Van Gemund, A.J.C. (author)Because of constraints imposed by the market, embedded software in consumer electronics is almost inevitably shipped with faults and the goal is just to reduce the inherent unreliability to an acceptable level before a product has to be released. Automatic fault diagnosis is a valuable tool to capture software faults without extra effort spent...report 2006

Feldman, A.B. (author), Pietersma, J. (author), Van Gemund, A.J.C. (author)Model-Based Reasoning (MBR) over qualitative models of complex, real-world systems has proven succesful for automated fault diagnosis, control, and repair. Expressing a system under diagnosis in a formal model and infering a diagnosis given observations are both challenging problems. In this paper we address these challenges. By building a fault...conference paper 2006
