Testing the Fault Tolerance Mechanisms (FTMs) is crucial for the development of today’s Web Service applications. In this work, we propose a methodology for assessing the performance and the efficacy of FTMs applied to Web services applications. We present a tool that uses application level fault injection techniques to inject communication faults by using a network Emulator Service without any modification to the system. The tool also generates additional workload on the tested system in order to produce more realistic results. The tool offers full control over the emulated environments in addition to the ability to inject application specific faults.
