An OSLC-based environment for system-level functional testing of ERTMS/ETCS controllers

•Environment supporting testing automation in railway domain.•OSLC standards supports the collaboration of existing/novel tools.•Industrial case study to exemplify the features and the usage of the environment. Product and application life-cycle management (PLM/ALM) are the processes that govern a product and a software system, respectively, encompassing the creation, deployment and operation of a system from the beginning to the end of its life. As both PLM and ALM require cross-discipline collaboration and cooperation, tools integration and inter-operation are necessary to enable the efficient and effective usage of tool suites supporting the management of the entire system life-cycle and overcome the limitations of all-in-one solutions from one tool vendor. In this context, the Open Services for Life-cycle Collaboration (OSLC) initiative proposes a set of specifications to allow a seamless integration based on linked data. This paper describes the work performed within the ARTEMIS JU project CRYSTAL to develop an environment for the functional system-level testing of railway controllers, relying on OSLC to enable inter-operation with existing PLM/ALM tools. A concrete realization of the proposed architecture is described also discussing some design and implementation choices. A real industrial case study is used to exemplify the features and the usage of the environment in testing one of the functionalities of the Radio Block Centre, the vital core of the European Rail Traffic Management System/European Train Control System (ERTMS/ETCS) Control System.
