One of the best videos I have watched on InfoQ. I love the simplicity of the approach. Like skiing though, it is harder to do than to understand.
As I watched the video I was struck how many of the approaches started with the inputs. It would be interesting to see what would happen if you restricted the exercise to start with the output.
Test 1. A winning board.
Test 2. An incomplete board.
Test 3. A board in stalemate.
I wonder if the developers would get caught up on the complexity of the internals that way?
Anyway, great session.

To me, that was: Here's the rules - go figure it out yourselves.
Some of the guys tried and failed - esp those guys with the 3*3 array....did they learn a lot? My guess is they learned to be turned off TDD.
Thought he could have given a few better hints + pointers, especially when they were trying to get out of the blocks.
Also would love to have been told at the end what Keith thought a good first test might be, and some reasons why.
I'd also suggest Keith read "Growing object oriented software, guided by tests".
(And/or www.jmock.org/oopsla2004.pdf)
Many notions in TDD have moved on and evolved some since the days of Kent Beck.

Hi Keith,
Thank you for your presentation. Ideally, I would like to have your code sample. Other readers might think so too.

Steve Freeman and Nat Pryce, the authors of GOOS, both have attended the workshop a couple of times (Nat was in this session in Cambridge!) They and I are quite aligned on how TDD works and has developed. Nat and I have used this workshop together at other conferences to address various aspects of TDD.
