Title: Semantic Mutation Testing

Abstract: Mutation testing uses operators to simulate potential faults in a software artefact. Traditional mutation operators make small syntactic changes and so can be seen as simulating slips made by the developer. However, a developer might make mistakes in their understanding of the semantics of the language used; in semantic mutation testing we simulate such potential misunderstandings through semantic mutation operators. The aim is therefore to capture a different class of possible mistake. This talk will describe semantic mutation testing and scenarios in which it might be particularly valuable and will say a little about our experiences in applying it to drive testing to find floating point comparison problems in C code.
