Model-based conformance testing aims to assess the correctness of an implementation with respect to a specification. This raises the question of a proper conformance relation that should be established between implementations and specifications. One commonly used conformance relation is the so-called input output conformance (ioco), which is defined over labeled transition systems. In this paper we investigate a denotational semantics of the input output conformance relation over reactive processes. We formalize the underlying assumptions of the ioco relation in terms of formal healthiness conditions and by adopted choice operators. Finally, we show that our denotational version of ioco can be generalized in the same way as the original relation. Our work aims to provide a unification of input output conformance by lifting the definition from labeled transition systems to reactive processes.
