A friend, having recently upgraded to Rhino Mocks 3.5, expressed his confusion regarding when to use mocks vs. stubs. He had read Martin Fowler’s Mocks Aren’t Stubs (recommended), but was still confused with how to actually decide whether to use a mock or a stub in practice. (For a pictorial overview, check out Jeff Atwood […]
My first dnrTV episode went live today. I am talking with Carl Franklin about dependency inversion, dependency injection, and inversion of control. I demonstrate how to build a very simple IoC container. My intent is to show developers that it isn’t any thing crazy scary. I talk about how IoC facilitates decoupling dependencies and creating […]
I’m writing some integration tests around the .NET PetShop, which has no tests whatsoever. Since the architecture is tightly coupled, you can’t really start writing unit tests effectively. You have to start applying Michael Feather’s techniques for breaking dependencies. Before doing that, I want some smoke tests around the application. That’s where WatiN comes in. […]
Another DevTeach has come and gone. I had an awesome time. I enjoyed hanging out with old friends and meeting some new ones. I saw a lot of great sessions, but the best part, as always, is the hallway and bar conversations. (No, I still haven’t quite figured out Metastones, even after playing for hours.) […]
During my geekSpeak screencast last week, one of the attendees asked: Any recommendations for refactoring existing code to insert interfaces? (e.g., what’s the best dependency to break first, the database?) Excellent question! Most of us do not have the luxury of working on greenfield projects, but instead work on brownfield projects – existing applications that […]
Today at lunch* I’ll be joining Glen Gordon and Lynn Langit on geekSpeak to talk about Taming Your Software Dependencies. Specifically I’ll be talking about moving from tightly-coupled to loosely-coupled architectures using dependency inversion, dependency injection, and inversion of control containers. geekSpeak is an interactive LiveMeeting driven by audience questions with no PowerPoint and lots […]
My latest article just hit the web in the March 2008 issue of MSDN Magazine. Loosen Up: Tame Your Software Dependencies for More Flexible Apps takes you on a journey from a highly-coupled architecture, which we’re all familiar with, to gradually more loosely-coupled ones. First stop is the problems inherent in highly-coupled applications. To start […]
DISCLAIMER: For the agilists reading this post, there is nothing new here. I just hear a lot of misconceptions around terms like YAGNI and wanted to provide my own take on things. YAGNI is an acronym for “you ain’t gonna need it”. You often hear it bandied about agile shops. One developer suggests an over-architected […]
I spent last week hanging out at DevTeach in Vancouver. Awesome conference. Although heavily Canadian, people from around the world showed up. (I finally got a chance to meet Oren Eini (aka Ayende Rahien) in person after emailing/IMing/etc. for a long time.) The Agile track was particularly well-attended, often with standing room only available. Of […]
