ETSI TR 103 386 provides an overview of the approach taken within the EU-funded research project called MIDAS to design, build and deploy an integrated framework for testing automation that will be available as a Test as a Service (TaaS) on a Cloud infrastructure, and which covers key testing activities: test suite generation, test execution, scheduling, evaluation and test results arbitration. While MIDAS is focused on the test automation for Service Oriented Architecture (SOA), the testing methods and technologies that are investigated and prototyped within the project can be generalized to a greater degree and can be applied not only to SOA System Under Test (SUT), but also to SUTs in other domains, e.g. Automotive, Telecommunications, Machine-to-Machine services. Such broader application relates particularly to model-based test design and test suite generation, model checking of choreographies for sound interaction of test scenarios, fuzzing for security testing, usage-based testing, probabilistic inference reasoning for test evaluation and scheduling.
