Yes. that is what I was trying to point out. Maybe I didn't succeed.
Most people do 1,2,3; 1,2,3; 1,2,3. If they are lucky and no tests
break, then they go back to one of the previous three iterations
and break 1 then run 3, see it fail, and say to themselves, "ok, my
tests are working",  go back, fix 1, and continue on.

It is best to do the following:
   1) write test
   2) run test and see it fail
   3) write code
   4) run test and see it succeed (hopefully) :)
