On today’s show, we embark on a new, evil adventure, one on which we hope you will join us! We’ll be looking at another refactoring problem and this will make up the first part of a short series of episodes dealing with this issue. Emmanuel lays out the topic, which takes the shape of a code used to run the rental of videos in an old style video store.

During this week’s discussion, we deal with the first areas of the topic, looking at what Emmanuel’s work takes directly from Martin Fowler’s Refactoring and where his actions diverge. We discuss the conditions and objects that deal with the duration of a rental and how these differ across genres of movies. We also unpack test names and start on the topic of his commits. Be sure to tune in for this especially evil episode!
