Dutch railways are implementing ERTMS, the new European railway traffic management system. Part of the endeavor consists of integrating the Dutch legacy train speed monitoring system (ATB) as a (STM) module into ERTMS. To this end, safety-critical embedded soft and hardware were developed. As a member of the verification team, I had the role of lead test engineer. I was responsible for supervising test designs and implementation. Test plans were written in the Polarion requirement management system. Test descriptions were linked to requirements, establishing traceability. By designing quality processes, I ensured that the approach complied with the EN50128 SIL3 norm. I implemented tests in Python or directly in (on target) C. I worked together with international parties on the implementation of a system test. I developed a test framework which performs on target tests using a custom Jupyter Python kernel by integrating the GDB debugger and CTC++ code coverage tooling. This setup allows direct access to the firmware without requiring instrumentation. The test framework integrates with Polarion RQMS and Jira. Docker was employed for configuration management. All tests were automated using Jenkins and CMake.
