“Kata2 (型 or 形 literally: "form"), a Japanese word, are the detailed choreographed patterns of movements practised either solo or in pairs. The term form is used for the corresponding concept in non-Japanese martial arts in general.”
Well, I'd never done one of those, so I signed up enthusiastically.
We spent a couple of hours in pairs, (xtreme programming, yay!) to do the Kata. In this case it was regarding Bowling Scores4 5 provided by Uncle Bob8.
It is very interesting, and I decided to spend a little more time in my limited spare time to see what I could come up with. I do notice almost immediately that I always try and capture the domain (in this case, scores, rolls, frames, spares and strikes) into Objects/Classes. It's a challenge to not immediately grab to my standard toolbox. It's also great to get some tests done, before diving into coding.
It is also a challenge to properly read requirements.
I retrieved the git repo from  and forked it over in my own github  to work on. There's nothing there yet, but that will change once I have something that looks half decent.
