X-Machine Based Testing for Cloud Services.

In this article we present a tool designed for cloud service testing, able to generate test cases from a formal specification of the service, in form of a deterministic stream X-machine (DSXM) model. The paper summarizes the theoretical foundations of X-machine based testing and illustrates the usage of the developed tool on some examples. It shows in detail how the specification should be written, which are the design for test conditions it should satisfy, in order to assure the generation of high quality test suites for the cloud service.
