In legacy code, one of the most important considerations is that we don't have tests around much of our code. What's worse, is that getting them in place is difficult. That's why many people are tempted to go back to the techniques we learned in the last chapter (sprouting and

How long does it take for you to make a change? If I ask this to 100 different people, I will get 100 different answers. The answer varies widely. So in projects with unclear code, many changes take a long time. On the other hand, in clearer areas, this can
