Testing of service-oriented software: a metamorphic testing approach
Yunwei Dong · Journal of Computer Applications · 2011
During the process of service-oriented software testing,Oracle problem that the program result is unpredictable comes into existence frequently because of issues like the unknown communication partners before the service discovery and the potential existence of non-identical implementations of the same service.In this paper,based on the benefits of the SOA environments,Metamorphic Testing(MT) approach was applied in the phase of unit testing and integration testing of service-oriented software.Metamorphic Relation(MR) can be built according to the service properties.A metamorphic testing class can invoke relevant services to execute test cases and use their metamorphic relations to detect failures.Any violation of any relevant metamorphic relation indicates a failure.
