Assert.AreEqual失敗。預計：<XmlResult>。實際：<XmlResult>

Question

我是單元測試新手，所以可能是我做錯了什麼。

我有一些XmlResult類：

public class XmlResult : ActionResult 
    { 
     public XmlDocument Document { private get; set; } 

     public override void ExecuteResult(ControllerContext context) 
     { 
      //Do something 
     } 
    } 

我也有控制器擴展方法：

public static class ControllerExtensions 
    { 
     public static XmlResult Xml(this Controller controller, XmlDocument document) 
     { 
      return new XmlResult { Document = document }; 
     } 
    } 

和測試方法：

[TestClass] 
    public class ControllerExtensionsTests 
    { 
     #region Xml 
     [TestMethod] 
     public void XmlExtensionShouldReturnCorrectValue() 
     { 
      // Arrange 
      var mockRepository = new Mock<T>(); 
      var productsController = new ProductController(mockProductRepository.Object); 

      var someXmlDocument = new XmlDocument(); 

      // Act 
      var actual = productsController.Xml(someXmlDocument); 
      var expected = new XmlResult { Document = someXmlDocument }; 

      // Assert 
      Assert.AreEqual(expected, actual);    
     } 
     #endregion 
    } 

而且磨片我打電話Assert.AreEqual(expected, actual);我的測試失敗，消息"Assert.AreEqual failed. Expected:<XmlResult>. Actual:<XmlResult>."。我究竟做錯了什麼？？？

我會在您的xml結果類中添加一個重寫equals方法，併爲equals比較執行您自己的實現。

類似下面....

public class XmlResult : ActionResult 
{ 
    public XmlDocument Document { private get; set; } 

    public override void ExecuteResult(ControllerContext context) 
    { 
     //Do something 
    } 

    public bool Equals(XmlResult other) 
    { 
     if(ReferenceEquals(null, other)) 
     { 
      return false; 
     } 
     if(ReferenceEquals(this, other)) 
     { 
      return true; 
     } 
     return Equals(other.Document, Document); 
    } 

    public override int GetHashCode() 
    { 
     return (Document != null ? Document.GetHashCode() : 0); 
    } 
}
