I am just starting with patterns and good my hands on a book that talks about the DDD patterns.

also, what happen to the challenge?

One of the problems I ran into at the beginning was that the codebase was still changing fairly frequently. When you’re trying to emulate behavior, that can be frustrating!

I’d like to wait for a stable release before giving it another crack.

Maybe a good compromise is a screencast only of the initial planning work and the start of the first iteration, so people can get an idea of the kind of process that was used to create the end result?

I’ve read loads of work on TDD and iterative development, but when it comes to putting it into practice I find it tough to link up planning, stories, and finding a good place in the not-yet-design to start writing tests. If you could put some of that into a screencast (or summarise it in a blog post) that would be invaluable for people like me that are keen to learn but don’t have a mentor.

I’ve been trying to do a similar thing in a blog series developing a Snakes and Ladders-like game, but being n00b with it all I think I’ve already made a mistake by not working top-down. (At http://davesquared.blogspot.com/2008/05/garden-race-series.html, if you’ll kindly excuse shameless link-dropping)

Anyway, good luck with the experiment and will be keen to see the output from it, be it code or screen cast.

I’ll definitely consider doing screencasts. The goal might not be to show the process, but the end result (or maybe just checkpoints along the way). It’s hard to produce the process you’d take in a reasonable fashion, though Rob does it well.
