Many systems interact with their environment at physically distributed interfaces and the distributed nature of any observations made is known to complicate testing. This paper concerns distributed testing, where a separate tester is placed at each localised interface and may only observe what happens at this interface. Most previous work on distributed model based testing has used models that are either finite state machines or input output transition systems. In this paper we define a framework for distributed testing from timed input output transition systems along with corresponding test hypotheses and a distributed conformance relation.
