Concolic testing is a popular dynamic validation technique that can be used for both model checking and automatic test case generation. We have recently introduced concolic testing in the context of logic programming. In contrast to previous approaches, the key ingredient in this setting is a technique to generate appropriate run-time goals by considering all possible ways an atom can unify with the heads of some program clauses. This is called "selective" unification. In this paper, we show
