我有一个演示者类,它附加了注入视图的事件.现在我想测试演示者对事件的正确反应.

这是视图界面IView:

public interface IView

这是实现IView的视图

public partial class MyView : IView

    }

    public void UpdateView(string test)
    {
        this.textBox.Text = test;
    }

    private OnSelectedIndexChanged(Object sender, EventArgs e)
    {
        if (this.MyEvent != null)
        {
            this.MyEvent(sender, e);
        }
    }
}

public class MyPresenter
{
    private IView _view;
    public MyPresenter(IView view)
    {
        this._view = view;
        this._view.MyEvent += this.OnMyEvent;
    }

    private void OnMyEvent(Object sender, …
