Software development work flows for safety relevant software require that each artefact is tested by at least one test case. An automatic overnight test case execution process supplying the newest results every morning makes this time-consuming process more efficient. This paper describes a tool framework consisting of the BusScope, the TCBP (Test Case Batch Processor) and WEFACT (Workflow Engine For Analysis, Certification and Test). It manages all necessary steps: initialization of the test objects, execution of the test cases by applying test patterns and test evaluation to find the test verdict – Passed or Failed. It supports automation of the certification process by managing requirements and collecting evidences for the safety case. A demonstrator, a steering actuator of a steer-by-wire application with redundant components, implemented on a real hardware and software platform, shows the proposed fully automated test case execution. The demonstrator was developed in the EU-funded research project SafeCer (Research partly funded by ARTEMIS-JU Call 2011 project no. 295373 (nSafeCer)).
