  This paper presents a framework to apply property-based testing (PBT) on top
of temporal formal models. The aim of this work is to help software engineers
to understand temporal models that are presented formally and to make use of
the advantages of formal methods: the core time-based constructs of a formal
method are schematically translated to the BeSpaceD extension of the Scala
programming language. This allows us to have an executable Scala code that
corresponds to the formal model, as well as to perform PBT of the models
functionality. To model temporal properties of the systems, in the current work
we focus on two formal languages, TLA+ and FocusST.
