In a class I recently taught, the students created a simple payroll system using Test Driven Development. Different students made different amounts of progress, some almost finishing the example I'm about to post, and some not quite so far. But they all asked for my solution. I have already posted the code to my solution, but now I want to talk about how I went about creating it. Hopefully this will share my Test Driven thought processes with my students and anyone else who might be reading.
