How Do I Use the MoqAutoMocker that comes with StructureMap 2.5.3?

Question

I'm trying to use the MoqAutoMocker class that comes with StructureMap and I can't find any examples of how it should be used. All I have to go on is the example at the StructureMap site that uses RhinoMocks.

What I'm trying to do is get reference to one of my auto-mocked/injected dependencies using the Get method. According to that link above, I should be able to do something like this

    // This retrieves the mock object for IMockedService
    autoMocker.Get<IMockedService>().AssertWasCalled(s => s.Go());

Note how you can use AssertWasCalled, which inidcates that the Get function returns a reference to the RhinoMocks Mock object? This same bit of code doesn't work for me when I use the MoqAutoMocker.

I have a class SignInController that depends upon an ISecurityService in the constructor. Using the MoqAutoMocker like the RhinoAutoMocker is used in the example, I think I should be able to do this...

var autoMocker = new MoqAutoMocker<SignInController>();
autoMocker.Get<ISecurityService>().Setup(ss => ss.ValidateLogin
(It.IsAny<string>(), It.IsAny<string>())).Returns(true); 

But the problem is that I never get access to the Setup method. In this case, the call to autoMocker.Get seems to be returning an instance of ISecurityService and not Mock<ISecurityService>

Has anyone successfully used MoqAutoMocker this way? Am I just doing it wrong?

Answer 1

I recently ran into a simillar problem. It seems that the solution is to do something like this:

var autoMocker = new MoqAutoMocker<SignInController>();
var mock = autoMocker.Get<ISecurityService>();
Mock.Get(mock).Setup(ss => ss.ValidateLogin
(It.IsAny<string>(), It.IsAny<string>())).Returns(true);

I have also posted a lengthier example on my blog: Setting Expectations With StructureMap’s MoqAutoMocker.

autoMocker.Get<ISecurityService>()
will return ISecurityService and you can't Setup on it. In contrary
Mock.Get(mock)
will return Moq.Mock, then you could Setup on it.
