Here you can find tutorials about some matters that I came across with during my daily job.
These tutorials are very simple - sometimes trivial - on purpose; their meaning is to show you the concepts behind the problem.
Since I'm trying to reach an high level of proficiency in XP, the tutorials will contains one or more unit tests, sometimes integration and acceptance tests as well, that will turn green during the each step we will make.
Beware, as I said, you won't find (at the moment) topics that require high skill in programming; the tutorials are supposed to be easy to understand.
This will be an exercise for me, and as a reflection this will be (hopefully) of help to you.
Please, feel free to write whatever comes to your mind, every suggestion is welcome!!!
Thank you in advance.
