class in a view that will cause its corresponding presenter to
react by changing its state:
CopyC#
CopyC#var mockView = new Mock<IOrdersView>(); var mockedEvent = mockView.CreateEventHandler<OrderEventArgs>(); var presenter = new OrdersPresenter(mockView.Object); // Check that the presenter has no selection by default Assert.Null(presenter.SelectedOrder); // Create a mock event handler of the appropriate type var handler = mockView.CreateEventHandler<OrderEventArgs>(); // Associate it with the event we want to raise mockView.Object.Cancel += handler; // Finally raise the event with a specific arguments data handler.Raise(new OrderEventArgs { Order = new Order("moq", 500) }); // Now the presenter reacted to the event, and we have a selected order Assert.NotNull(presenter.SelectedOrder); Assert.Equal("moq", presenter.SelectedOrder.ProductName);
