起訂量 - 驗證上次調用的方法

Question

public interface IMouseTraits 
{ 
    void ForceCursor(Cursor cursor); 
    void SetCursor(Cursor cursor); 
} 

1）我如何驗證給setCursor最後一次通話是與允許Cursors.Arrow（多次調用和的setCursor與ForceCursor不同參數）。

2）如何確認SetCursor和ForceCursor的最後一次調用是SetCursor（多次調用SetCursor和ForceCursor並允許變量參數）。

[Test] 
public void AfterOperationCursorIsArrow() 
{ 
    var mock = new Mock<IMouseTraits>(); 

    varw = new WindowOperation(mock.Object); 
    w.Execute(); 

    mock.Verify(traits => traits.SetCursor(Cursors.Arrow)); // ? 
} 

Answer 1

您可以使用調來捕獲電話：

[Test] 
public void AfterOperationCursorIsArrow() 
{ 
    string lastMethod = null; 
    Cursor lastCursor = null; 

    var mock = new Mock<IMouseTraits>(); 

    mock.Setup(m => m.ForceCursor(It.IsAny<Cursor>())) 
     .Callback((Cursor c) => lastMethod = "ForceCursor"); 

    mock.Setup(m => m.SetCursor(It.IsAny<Cursor>())) 
     .Callback((Cursor c) => { 
      lastMethod = "SetCursor"; 
      lastCursor = c; 
     }); 

    var w = new WindowOperation(mock.Object); 
    w.Execute(); 

    Assert.That(lastMethod, Is.EqualTo("SetCursor")); 
    Assert.That(lastCursor, Is.EqualTo(Cursors.Arrow)); 
}
