Experiences using Tedeso: an extensible and interoperable model-based testing platform

The integration of novel software quality assurance tools into existing development environments must be performed in ways that leverage the benefits of the tools while minimizing their impact on existing software processes. This supports the adoption of new methodologies with minimal interference into core business practices. This paper discusses the design of Tedeso, an extensible and interoperable model-based testing platform developed to facilitate the automatic generation of tests, while supporting the needs of different stakeholders in a diverse and broad organization. We discuss Tedeso key design characteristics, in particular its extensibility and interoperability, provided through the use of a workflow-driven service-oriented architecture, and show how it has enabled and facilitated the adoption of model-based testing techniques in different business units in different sectors within SIEMENS. We also discuss some issues that come from the adoption of service-oriented architectures, showing how they have been managed in our platform.
