I get nods when I demand some form of automated testing because "everyone's IQ and experience tends to become irrelevant at 3 am when you're tired and hungry working on a critical bug before the release ships." I ask people if they trust that developer, not the usual person you know. Beyond that, there's few better ways to show how to use a piece of code than by writing a test that actually does use it as you would, so it cuts down on some documentation if people can trust that it'll be there.
