Using Linq to Test Your Query Logic Without Touching The Database
That’s right, I said it, I’ve been doing it, and I abso-effin-lutely love it. A few months ago my co-worker, Troy, posted a question on Stack Overflow. We were doing integration testing on a project we were working on, and as the object graph grew larger, the code required to test query logic became painful. Since I am a sissy and don’t like pain, Troy asked the question on SO about how we might do it less painfully, and we got this answer, and it totally changed our TDD/BDD lives. The answer came ......

Be Careful What You Inject
When testing, I find that it is important to be cognizant of what you’re testing. I’ve seen (and done) tests where I was using my IoC container to inject a dependency. You may think, “That’s the way it will work in the real world.” The problem is, it may have nothing to do with the System Under Test (SUT). So, you’re test might fail because something went wrong with your IoC container or configuration and have nothing to do with your SUT failing at all. The important thing to remember is test what ......

Three Ways to Register Dependencies with StructureMap 2.4.9
I've been using StructureMap for my dependency injection container for a little while now and I wanted to discover all the ways (I could find) to register my dependencies. Here's is what I came up with (If you know of more or see something wrong drop me a comment): I've got a project with a console app, a project for my dependencies (memento and concrete types), and a project that does my dependency registration (when I do it in code). My console app just gets the default concrete type first, then ......

Dependency Injection Containers
I've spent the last week reading about Dependency Injection, and I think I may finally understand. First of all it is a type of Inverion of Control. Now .NET programmers see inversion of control all the time. Usually in the same place we encounter delegates: event handlers. The event handler actually controls the handling of the event and not the main program. But Dependency Injection is a step beyond. DI inverts control of the program so that a dependent object is injected into its dependant object. ......

What's with all the NEW stuff?!!??
As I get settled in at this new job, I begin to take stock of what the company wants to accomplish: a solid, extensible product with the longest possible useful life. Given the fact that this product will probably take 2-3 years (total) to develop, that means learning the newest stuff and looking at some technologies that have yet to be released. The new technologies coming out of Microsoft in the next six to twelve months is staggering. Beyond products (like Windows 2008, SQL Server 2008 and Visual ......

TDD, MVC, IOC/DI & ASP.NET (MAN! that's a lot of initials!)
I am creating a blog engine. Not because the world needs another, but because there are some techniques I want to learn about and creating this very straight-forward project will allow me to do that. First step was to create the project and start experimenting with Test-Driven Development inside MVC for ASP.NET. I started by searching for TDD MVC and ASP.NET which led me to this article by phil haack. While trying to put together some of my first tests, I had to use a mock object. The easiest way ......
