Abstract : Testing Fault Tolerance Mechanisms FTM-s is crucial for the development of today-s Web Service applications. In this work, we propose a methodology for assessing the efficacy of FTMs applied to Web services applications distributed over the Internet. We present a tool that uses application level fault injection techniques to inject communication faults by using a network Emulator Service. The emulator also generates additional workload on the tested system in order to produce more realistic results. As well as allowing the user to generate a fault model script, the tool provides, by analyzing WSDL documents, the ability to inject selected faults into the exchanged SOAP messages. The tool can be used to test either a single Web Service or to test composed services without any modification to the system under test.
