I would really, really like to see Xamarin introduce a class based around this subject. So many companies are requiring XP/Agile TDD based development these days - it's virtually a fundamental of modern software development, and the NUnitLite documentation on xamarin.com (and nunitlite.com for that) is pretty sparse. I've asked around on these forums before for good resources/tutorials, and not had any responses.
Perhaps it could even bring in a bit of BDD with Calabash/Cucumber although I appreciate that this is less of a core skill and something of an emerging approach.
Alternatively, is this something that could be discussed directly during one of the "Office Hours" sessions? When I signed up for University I was under the impression that we got a couple of personal sessions with an engineer or Xamarin expert, but since the change to the 1-year subscription thing I haven't heard any more about it or really know much about how we can use it.
