If you have not checked out the new AutoMocking Container that is part of StructureMap 2.5 I would highly suggest you do, it rocks.

I thought I would show how simple it is to create a PartialMock on the Class under Test (CUT) when using the RhinoAutoMocker.

Our Class we want to mock

public class VisitReassignmentRule : PersistingRule
{

    public VisitReassignmentRule( ISynchronizationRepository synchronizationRepository, 
	IValidationRepository validationRepository, 
        IValidationLogger validationLogger ) : base( validationRepository, validationLogger )
    {
        SynchronizationRepository = synchronizationRepository;
    }

    public override InvocationActions ProcessRule( DataSet ds )
    {

	// logic goes here

        return null;
    }

    public override bool DataIsInviolationOfRule( DataSet dataSet )
    {
        return false;
    }

    private ISynchronizationRepository SynchronizationRepository { get; set; }
}

Mocking Code

[Test]
public void ProcessRule_ViolatesRule()
{
    	var rule = new RhinoAutoMocker();

	// This line here tell the mocking container to make it a partial ( I know, the method name tells u that to)
    	rule.PartialMockTheClassUnderTest();
    	rule.ClassUnderTest.Expect( x => x.DataIsInviolationOfRule( null ) ).IgnoreArguments().Return( false ).Repeat.Any();

	// actually call the method
    	rule.ClassUnderTest.ProcessRule( dataset );
}

As you can see, telling the AutoMocking container that you want the Class under Test to be a partial is very easy.  The one thing you want to make sure you do is not use the .Get<> syntax and just use the .ClassUnderTest syntax to set your expectation.

Till next time,
