Use of two or more fault injection tools in a test campaign enriches the scenario obtained from a test execution. Faultloads represent the main input for these tools but their specification mechanisms lack usability and expressiveness. This paper presents a full test scenario featuring the use of jFaultload, which applies Java for the specification of fault-loads and translates them to specific formats that are appropriate to each available fault injector. FIRMAMENT, a fault injector for communication systems, was integrated in the environment and completes the test scenario. The service under test used to demonstrate the usability and expressiveness of our solution is a video streaming session using RTP Protocol.
