FizzBuzz Setup Suggestion

Page 48 says;

“It's not doing much of anything, but what we have here is, in fact, a full-fledged test case. We could execute our test suite right now, and the framework would run it.”

It took me some back and forth to previous recipe to get my test suite to run without an error. Since these first few are targeting beginners and it’s not much code what do you think about showing a code summary of what is needed to type rake and there be no issues?

My commit to get it setup

I'll look at it for the next update. I probably won't write out every line of code needed to make the project work (since you kinda need the same for every recipe), but I could make it more clear that you should first read Add Minitest to Your Ruby Project if you don't already know how.
