Code Kata at the Dojo

At my work, the software architect asked if people were interested in getting together at work of an evening and doing a Kata¹.

“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 Scores^{4 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 [6] and forked it over in my own github [7] to work on. There's nothing there yet, but that will change once I have something that looks half decent.
