Screencast: Test-driven development of FizzBuzz

I plan to develop a screencast showing how to write the program below using very low-tech test-driven development.

“Write a program that prints the numbers from 1 to 100. But for multiples of three print “Fizz” instead of the number and for the multiples of five print “Buzz”. For numbers which are multiples of both three and five print “FizzBuzz”.”
