For example, when I was writing pacemakers--you better believe we tested the *crap* out of our code. Were we the *only* ones testing? Of course not; there were *many* levels of testing--but it *started* with us. > Tests are also done on hardware electrical rigs , simulating feed to > sensors. > Yep. And when I was writing fuel pump controllers not only did *I* have a set of tests, so did the hardware guys, so did the combination of HW/SW guys, so did the verification group, so did whoever gave us our certification, etc. It's not entirely clear to me what your point is, or if you're just arguing for the sake of arguing. Testing is, by necessity, the responsibility of everyone involved in the project, which includes the developer. d.
