Title:

Model-based mutation testing

Abstract:

Model-based mutation analysis is a powerful but expensive testing technique. We tackle this problem by proposing an optimization technique that drastically speeds up the mutant execution process. Central to this approach is the Featured Mutant Model, a modeling framework for mutation analysis inspired by the software product line paradigm. It uses behavioral variability models, viz., Featured Transition Systems, which enable the optimized generation, configuration and execution of mutants.

Mutation testing also requires detecting mutants whose behaviour is equivalent to the original system. For finite behavioural models, the Equivalent Mutant Problem (EMP) can be transformed to the language equivalence problem of non-deterministic finite automata.

We compare a state-of-the-art technique for language equivalence to two simple, randomised techniques.

Bio:

Pierre-Yves Schobbens graduated in Philosophy in 1982, in Applied Mathematics and Economics in 1983, in Computer Science in 1984, magna cum laude, and received his PhD in 1992 all from the University of Louvain, Belgium. He then worked as a permanent researcher for the CNRS in Nancy, France. He is currently full professor at the University of Namur, Belgium, since 1994.

He was also invited professor at IST Lisbon, Ecole Normale Supérieure (Cachan), Ecole Centrale (Nantes), universities of Birmingham, Brussels, Toulouse, Grenoble.

His current research interests include software product lines, software evolution, formal methods, agent-oriented software engineering, model checking and the underlying theory: semantics, logics and automated reasoning.

He was vice-Dean from 1995 to 1997. He is the Chair for International Relationships of his Faculty. He is (co-)author of about 140 papers, editor of 7 proceedings. He is member of the expert groups WG1.3 and 5.8 of the International Federation for Information Processing (IFIP).
