TDD in Excel - instructions and journal
Help! I've just written up a 15 page PDF showing how I use TDD and Excel to solve the roman numerals problem.
Eventually I want to add it to my book as an appendix, but first I want to share it with the world. I think it is a great example to give to managers or non-techies to get a feel for TDD.
The trouble is ... I've just finished it and I need feedback on the document so that I can improve it. Can you help?
I'm interested in making it more understandable and more convincing. I'm not too bothered if my VBA skills are crap, but don't let that stop you pointing it out :)
Can you help?
Excellent paper! I like that you've taken the TDD and separated it from heavy code. Anyone who has fooled around with Excel can understand your paper. Well done.
One item, on page 9 when you are discussing your test for the value 14, you have '14=xix', which should be '14=xiv'.

Very nice treatment. I would have liked to have heard more about the fixes you found during refactoring / debugging.

This is excel-lent!
A great example of TDD. The only things I would say are: reduce the comments about how you haven't programmed a lot!; and add in a bit about how TDD helps you when a new requirement comes along (i.e. giving you a strong set of tests already in place).
