I like automating boring tasks, and one of them sometimes is integration testing. At Cpac Systems I have been writing scripts and configuring hardware for automatic testing of Electronic Control Units (ECUs). Basically connecting the essential control units for running a boat to the same system, and writing automatic test cases that perform hardware-in-the-loop (HIL) tests. All of it connected to Jenkins Continous Integration server.
