This work focuses on testing the consistency of distributed real-time systems when their configurations evolve dynamically, called also adaptable systems. In this context, runtime testing which is carried out on the final execution environment is emerging as a new solution for the validation of these systems. To reduce testing effort, cost and time, we apply the dependency analysis technique in order to identify affected parts of the system under test due to runtime reconfiguration. In addition, we propose a flexible and evolvable distributed test architecture made of two kinds of testers: Single Component Testers and Component Composition Testers. These testers execute unit tests (respectively integration tests) on the affected components (respectively component compositions) as soon as reconfiguration actions occur. An illustrative example describing interactions between the proposed testers when two reconfiguration scenarios happen is given.
