I am new to moq and I was trying to test a controller (MVC) behaviour that when the view raises a certain event, controller calls a certain function on model, here are the classes -

public class Model
{
    public void CalculateAverage()
    {
        ...
    }

    ...
}

public class View
{
    public event EventHandler CalculateAverage;

    private void RaiseCalculateAverage()
    {
        if (CalculateAverage != null)
        {
            CalculateAverage(this, EventArgs.Empty);
        }
    }

    ...
}

public class Controller
{
    private Model model;
    private View view;

    public Controller(Model model, View view)
    {
        this.model = model
        this.view = view;
        view.CalculaeAverage += view_CalculateAverage;
    }

    priavate void view_CalculateAverage(object sender, EventArgs args)
    {
        model.CalculateAverage();
    }
}

and the test -

[Test]
public void ModelCalculateAverageCalled()
{
    Mock<Model> modelMock = new Mock<Model>();
    Mock<View> viewMock = new Mock<View>();
    Controller controller = new Controller(modelMock.Object, viewMock.Object);
    viewMock.Raise(x => x.CalculateAverage += null, new EventArgs.Empty);
    modelMock.Verify(x => x.CalculateAverage());
    //never comes here, test fails in above line and exits
    Assert.True(true);
}

The issue is that the test is failing in the second last line with "Invocation was not performed on the mock: x => x.CalculateAverage()". Another thing I noticed is that the test terminates on this second last line and the last line is never executed. Am I doing everything correct?
