Nice! Thanks for that!
Found some other gems from Ned which Ive stuffed into my blog -- will put it in
the relevant thread

However I dont believe that Ned and Terry are talking the same thing -- though
closely related.
Ned is talking of how to do testing
Terry is talking of how to write clean (old-fashioned word 'structured') code
and using testing as an allurement.
They are not the same because if (say!) you were a genius who wrote
bug-free code on first attempt you dont need to test; you still need to write
clean code for others to read
