Title:
Answer-Set Programming as a New Approach to Event-Sequence Testing
Abstract:
In many applications, faults are triggered by events that occur in a particular
order. Based on the assumption that most bugs faults are caused by the interaction of a low number of events, Kuhn et al. recently introduced sequence covering arrays (SCAs) as suitable combinatorial designs for event sequence testing.
In practice, a direct application of SCAs for testing is often impaired by additional constraints. Also, the notion of SCAs has to be adapted to fit application specific needs. Modifying precomputed SCAs to account of problem variations can be problematic,
if not impossible, and developing dedicated algorithms is costly.
In this talk, we propose to use Answer-Set Programming (ASP) as a declarative paradigm for computing SCAs. Our approach allows to concisely state complex coverage criteria in an elaboration tolerant way, i.e., small variations of a problem specification require only small modifications of the ASP representation.
