RT book part T1 Using Constraint Solvers to Support Metamorphic Testing A1 Castro Cabrera, María Carmen A1 García-Domínguez, Antonio A1 Medina Bulo, María Inmaculada A2 Ingeniería Informática K1 Metamorphic relations K1 constraint solvers K1 con- straint programming systems K1 validation AB One of the current challenges in the context ofMetamorphic Testing (MT) is the formalization and validationof metamorphic relations (MRs), as there is no single methodor homogeneous way of doing it. It is a part of this softwaretesting technique that, unlike others, is not yet developed. Onone hand, the fact of having an artifact that formally validatesthese main elements in MT, facilitates the task for developersand testers and ensures that the technique applied fulfills itsfunction with guarantees. On the other hand, nowadays, thereare numerous accessible tools based on highly consolidatedand mature constraint solvers that can help in this processof validation. Interpreting MRs as a set of constraints, theirvalidation with these tools is directly applicable. This paperpresents a proposal based on a use case, in which MRs areimplemented as a set of restrictions. The experiments and theresults are described and future lines of research are outlined.
