Achieving SCA Conformance Testing with Model-Based Testing

The Software Communications Architecture (SCA) is a software architecture provided and published by the Joint Tactical Networking Center (JTNC). Facing the multiplicity of the waveforms and the diversity of the platform architectures and form factors, the original aims of the SCA are to facilitate the waveform development in terms of portability and waveform deployments onto heterogeneous Software Defined Radio (SDR) platforms. In this paper, we present an approach using Model-Based Testing (MBT) to ensure the conformance of a software radio platform with SCA requirements. In this approach, an MBT model is developed on the basis of SCA specifications, and conformance tests and scripts are generated and then run on the targeted software radio platform. This approach has been developed within a French research project, called OSeP, with results regarding modeling for automated test generation for SCA conformance testing. The techniques involved in this project focus on functional requirements and automatically generate Java executable test scripts, which aim to evaluate the functional conformance of the software implementation with respect to their associated requirements.
