Mocking Generic Method with NMock2 (part2)

Well although this feature has been mentioned on the web it doesn't seen to exist in any version of NMock2 I can find. With a bit of digging I worked out how to implement it myself.

You can download the assembly from NMock2Extensions try it out, or download the source from svn.

Here's an example of using it...

Stub.On(childScope)
      .Method(new GenericMethodMatcher("Get", typeof(IControl)))
      .Will(Return.Value(control));

Expect.Once.On(childScope)
      .Method(new GenericMethodMatcher("Get",typeof(IDocument)))
      .Will(Return.Value(NewMock()));

As you can see, you can Stub or Mock on the same method with different generic types and they are handled differently, as you would expect.

Happy Mocking

Getting Started with NDI

Check out Getting Started with NDependencyInjection. I'm looking for some feedback. How readable/followable is it?

Mocking templated methods with NMock2

Mocking a method like T GetSomething();

This is something that I have resorted to RinoMock to achieve in the past...
... well it turns out you can do it with NMock2 v1.0 as follows:

Expect.Once.On(a).Method("GetSomething", typeof(int)).Will(Return.Value(42));

I've tried to find this before.. and failed.. so I thought I should blog it to make it easier to find in google.

NDI: Unexpected bonus

NDependencyInjection Update:

Now that most of the code-base is using NDI we are really seeing the benefits.

The main bonus I'm getting is with how simple refactoring has become. Once you have the architecture modeling reality, whenever a class needs a service the correct instance is already available in the scope. This means all you need to do is ask for it in the constructor and it all just works. No wiring changes.

When did you last do a "Chicken Run"

"Chicken Run": The process of checking in new code and then leaving before the build has completed, leaving others to deal with the build if it breaks.
