Nothing much to, just that it took me some time to figure it out today. The code below tests whether DivisionID is actually set in the presenter.

public class Presenter
{
    readonly IRepository repository;

    public Presenter(IRepository repository)
    {
        this.repository = repository;
    }

    public IView View { get; set; }



    public void GetDivision()
    {
        View.DivisionID = repository.GetDivisionID();
    }
}

public interface IView
{
    int DivisionID { get; set; }
}

[TestFixture]
public class PresenterTests
{
    Presenter sut;
    IView view;
    IRepository repository;

    [SetUp]
    public void SetUp()
    {
        view = MockRepository.GenerateMock<IView>();
        repository = MockRepository.GenerateMock<IRepository>();
        sut = new Presenter(repository){View = view};
    }

    [Test]
    public void when_on_the_sut_GetDivisionID_is_called_it_should_set_the_divisionID_on_the_view()
    {
        //AAA mocking style
        
        //Arrange
        const int divisionID = 1;
        repository.Stub(s => s.GetDivisionID()).Return(divisionID);
        
        //note: the expectation is set when DivisionID is set to divisionID
        view.Expect(s => s.DivisionID = divisionID);
        
        //Act
        sut.GetDivision();
        
        //Assert
        view.VerifyAllExpectations();    
    }
}
