Some years back, Ron Jeffries set out to TDD Sudoku in a number of blog posts and failed to deliver a working solution.
This should be a cautionary tale to us - TDD on its own will not save you. How do you know if TDD is offering you little value to you in your real projects?
For the next few months (we'll see how each session goes before we call it a day), XPManchester will solving Sudoko the TDD way. Our aim is to become mindful of when TDD breaks down and trying to identify warning signs and anti patterns associated with it.
As for format, we'll be working as one or two groups, Randori style.
