In testing, a component with interface $$C_i$$ has its own local tester that interacts with $$C_i$$ and this local tester observes a local trace consisting of inputs, outputs and durations as perceived by $$C_i$$. An observation made in testing is thus a multi-trace: a tuple of (timed) local traces, one for each $$C_i$$. The conformance relation for such distributed systems combines a classical unitary conformance relation for localised components and the requirement that the communication policy was satisfied. By expressing the communication policy as a constraint satisfaction problem, we were able to implement the computation of test verdicts by orchestrating localised off-line testing algorithms and the verification of constraints defined by message passing between components. Lastly, we illustrate our approach on a telecommunications system. %G English %Z TC 6 %Z WG 6.1 %2 https://inria.hal.science/hal-01678964/document %2 https://inria.hal.science/hal-01678964/file/449632_1_En_17_Chapter.pdf %L hal-01678964 %U https://inria.hal.science/hal-01678964 %~ CEA %~ IFIP-LNCS %~ IFIP %~ CENTRALESUPELEC %~ DRT %~ IFIP-TC %~ MICS %~ IFIP-WG %~ IFIP-TC6 %~ IFIP-WG6-1 %~ IFIP-ICTSS %~ UNIV-PARIS-SACLAY %~ CENTRALESUPELEC-SACLAY %~ IFIP-LNCS-10533 %~ LIST %~ GS-ENGINEERING %~ GS-COMPUTER-SCIENCE %~ GS-SPORT-HUMAN-MOVEMENT
