Cloud computing and the future Internet concept highlight new requirements for the software engineering phases including testing and validation of modular web services. A major reason is because cloud applications are developed by services belonging to different providers, thus making software testing a really challenging issue. In this work, we propose a testing methodology that includes two fold testing actions; a unit testing of cloud service APIs following white and black box techniques and an integration testing strategy by identifying services that could interface with each other. In addition, we present the Elvior TestCast T3 (TTCN-3) testing tool for automation of use case testing. We demonstrate the results of the methodology when applied to different cloud services and we present a discussion of our conclusions for a real world use case, in which we applied this methodology.
