Abstract
We present a lightweight, automated tool for specification-based testing of declarative programs written in the functional logic programming language Curry and emphasize the usefulness of logic features in its implementation and use. Free variables, nondeterminism and encapsulated search turn out to be elegant and powerful means to express test-data generation.
