Test Execution Control with Timing Constraints for Testing Distributed Systems

The development of distributed testing frameworks is more complex, where the implementation process must consider the mechanisms and functions required to support interaction as long as the communication and the coordination between distributed testing components. The typical reactions of such systems are the generation of errors ‘set: time outs, locks, observability, controllability and synchronization problems. The first contribution in this study present a way to control the test execution of distributed testing components by introducing the synchronization messages and we show how the problems of control and synchronization can be solved by the same process. In other side, we show that in practice the distributed testing process must not only check if the exchanged events have been observed, but also the dates when these events have been occurred and then the distributed testing frameworks must consider some timing constraints.
