A brief introduction to THOTL

Abstract

In this paper we extend HOTL (Hypotheses and Observations Testing Logic) to provide a formal framework to test timed systems. The main idea underlying HOTL is to infer whether a set of observations (i.e., results of test applications) allows to claim that the IUT conforms to the specification if a specific set of hypotheses is assumed. In this paper we adapt HOTL to cope with the inclusion of time issues. In addition, we show the soundness and completeness of the new framework, that we call THOTL, with respect to a general notion of timed conformance.
