Test Driven Development

There's always distension between creating things and then cleaning up after ourselves, in programming, but also in other areas. So i guess some of the tension there is also just some decisions you make for the book. I was really trying to internalize these ideas and really trying to explore what is test driven development. The idea that iill come in later and write the test is completely backwards to me. It's kind of the same thing, like, my wife and i joked it like, no, once we had children, we had to start eating better.
