Remote testing of timed specifications

Abstract : We present a study and a testing framework on black box remote testing of real-time systems using Uppaal-TIGA. One of the essential challenges of remote testing is the communication latency between the tester and the system under test (SUT) that may lead to interleaving of inputs and outputs. This affects the generation of inputs for the SUT and the observation of outputs that may trigger a wrong test verdict. We model the overall test setup using Timed Input-Output Automata (TIOA) and present an adapted asynchronous semantics with explicit communication delays. We propose the ∆-testability criterion for the requirement model where ∆ describes the communication latency. The test case eneration problem is then reduced into a controller synthesis problem. We use Uppaal-TIGA for this purpose to solve a timed game with partial observability between the tester and the communication media together with the SUT. The objective of the game corresponds to a test purpose.
