Dustin Bartlett, one of the developers on the team here at Point2, was just in my office asking me about Mock testing. It turned into an interesting discussion about when to use Mock objects and when not to. 

Ultimately I suggested he take a look at some of the material at xunitpatterns.com, a site developed by Gerard Meszaros while he was authoring the book xUnit Test Patterns. I was fortunate enough to be mentored by Gerard on several projects I worked on in Calgary, and have a tremendous amount of respect for him and his knowledge when it comes to testing software.

After looking at xunitpatterns.com Dustin and I realized the real question was what type of Test Double should be used. For the problem at hand, we decided to go with a Configurable Test Double. If you are stuck on a testing problem, or just want to improve your testing skills, I strongly recommend looking at Gerard’s site and picking up his book.
