Test automation based on C / C++ / VB.Net COM and LabVIEW on Windows XP and Windows 2000
Automatic test environment for test cycles on diesel engine control units. Various sensors and actuators were driven directly or via COM servers using C/C++/C#. I implemented individual COM servers and wrote parts of the overall test automation. The COM servers basically simulate a subsystem that would otherwise be hard to integrate into the test setup. The goal was to test a software release of the engine control units in advance with relatively little effort.
