Ron Jeffries, of Extreme Programming fame, and some other folks on the
Test Driven Development email list, have started several passes at creating a Sudoku solver by
following the TDD approach. I really am enjoying following
Ron's pursuit in his article,
OK, Sudoku, and in the forum and list messages. Ron is doing a Ruby
version, which is even more fun to follow. If you want to see
TDD in action, watch as Ron goes about implementing something
about which he knew basically nothing when he started. Great
fun!
