I really wish this included examples of how to test your code, either in the form of "recipes" or in the examples. If I'm building something that I plan on maintaining for a medium to long amount of time, I'll want tests to give me some peace of mind. Especially when I go work on other stuff, and I come back a few months later to find myself stressed out because I don't know if things will break.
