As I do more and more work with the exercism.io community, I've noticed a reoccurring theme. There seems to be a lot of confusion around the various types of "test doubles" and what each of them actually do.Now, if you've had some exposure to test driven development already,…
Kathleen Dollard in the house!Well, that's a wrap! DEVintersection is over after a long week of sessions, technical difficulties, and an intense all-day workshop. I'm back in my hotel room at the MGM Grand, but we need to talk about everything that happened this week before I inevitably forget.…

Recently I stumbled across a test driven development article that mentioned something I had not heard before. It's a premise that Uncle Bob came up with as a means to order the priority of the transformations you should apply when practicing test driven development. He called it the Transformation Priority…
