使用Moq或任何其他模拟工厂从模拟存储库中检索模拟

Question

How can I retrieve a mock object from a mock repository using moq?

I have an application (mvc2) that wasn't really designed from the first time to support test units, but I am trying to adapt it. I have a service locator that creates the desired types.

basically what I want to do using a mock framework is replacing the variables that represent services in a method with mock objects, then I want to retrieve that mock objects and set them up.

So:

private ApprovalLevel GetApprovalLevel(Fusion Fusion)
{
    var ScopeofService=ServiceLocator.GetInstance<IScopeofService>();
    var programs=ScopeofService.GetPrograms();
    ...    
} 

In my test units I set the ServiceLocator to use a mock kernel that will mock up my IScopeofService this works fine. The mock kernel uses a mock repository sent as param MockRepository Moq, that will bind and create the desired mock for a desired interface.

Now I want to retrieve that mock in my test to setup a fake value to be returned for the GetPrograms() but I MockRepository doesn't have a get mock just methods to create new mocks.

Still he somehow keeps all the references to mocks because it has VerifyAll method.

Update

public MockNinjectControllerFactory(Moq.MockRepository mockRepository)
{
    Kernel = new StandardKernel(new MockNinjectServices(mockRepository));
}

public class MockNinjectServices : NinjectModule
{
    private readonly MockRepository _mockRepository;
    public MockNinjectServices(MockRepository _mockRepository)
    {
        this._mockRepository = _mockRepository;
    }

    // TODO MARIAN: Resolver should return actualy mock objects also to be able to set them.
    public void BindToConstant<T>() where T : class
    {
        Bind<T>().ToConstant(_mockRepository.Create<T>().Object).InSingletonScope();
    }

    public void BindMock<T>() where T : class
    {
        Bind<Mock<T>>().To(typeof(Mock<T>)).InSingletonScope();
    }

    public override void Load()
    {
        BindToConstant<IPaymentInvoiceRep>();
        BindToConstant<IPaymentInvoiceBL>();
    }
}

And the test itself:

[TestFixture]
public class DemoControllerFixture
{
    readonly MockRepository _mockRepository = new MockRepository(MockBehavior.Default);

    [Test]
    public void Should_MyMethod()
    {           
        EvedServiceLocator.Default = new MockNinjectControllerFactory(_mockRepository);
        var sut=new DemoController();

        // now if my sut has something that will resolve as mock created by my mockRepository I would like to retrieve that mock and set up something on it.            
    }
}

Use Moq.Get() to get the mock object from a concrete reference. In code:

[Test]
public void Should_MyMethod()
{           
    EventServiceLocator.Default = new MockNinjectControllerFactory(_mockRepository);
    var sut=new DemoController();

    var scopeService EventServiceLocator.Default.GetInstance<IScopeofService>();
    var mockScopeService = Mock.Get(scopeService);
    mockScopeService.Setup(p => p.GetPrograms()).Returns(/* TODO */); 
}
