c#中的mock依赖不起作用

我能够模拟会话，但是我不能成功地模拟sessionconfiguration类。如果你看到我的单元测试类在这篇文章的底部调用我的类的connect方法。调试时，connect方法中的Settings对象始终为空。你能告诉我可能有什么问题吗?

我有一个类叫XYZ。它声明了FixSessionConfiguration依赖项

Class XYZ
{
    [Dependency]
        public FixSessionConfiguration Settings
        {
            get;
            set;
        }
      public void Connect()
      {
            iFixSession = new FixSession(
            Settings.SenderCompID,
            Settings.TargetCompID,
            Settings.Version,
            Settings.SetResetSeqNumFlag);
      }
}

我基本上需要模拟FixSessionConfiguration类的单元测试。为此，我为会话配置创建了接口。下面是代码

public class FixSessionConfiguration : SessionConfiguration,ISessionConfiguration
    {       
        [ConfigurationProperty("senderSubID")]
        public string SenderSubID
        {
            get { return (string)this["senderSubID"]; }
            set { this["senderSubID"] = value; }
        }
        [ConfigurationProperty("senderLocationID")]
        public string SenderLocationID
        {
            get { return (string)this["senderLocationID"]; }
            set { this["senderLocationID"] = value; }
        }
        [ConfigurationProperty("targetSubID")]
        public string TargetSubID
        {
            get { return (string)this["targetSubID"]; }
            set { this["targetSubID"] = value; }
        }
       public new string SenderCompID { get; set; }
        public new string TargetCompID { get; set; }
        ProtocolVersion Version { get; set; }
        public new bool SetResetSeqNumFlag { get; set; }
        public new string Host { get; set; }
        public new int Port { get; set; }
}

SessionConfiguration类是第三方二进制文件的一部分。

public class SessionConfiguration : ConfigurationSection
    {
        [ConfigurationProperty("host", IsRequired = true)]
        public string Host
        {
            get { return (string)this["host"]; }
            set { this["host"] = value; }
        }
        [ConfigurationProperty("port", IsRequired = true)]        
        public int Port
        {
            get { return (int)this["port"]; }
            set { this["port"] = value; }
        }
        [ConfigurationProperty("senderCompID", IsRequired = true)]
        public string SenderCompID
        {
            get { return (string)this["senderCompID"]; }
            set { this["senderCompID"] = value; }
        }
        [ConfigurationProperty("targetCompID", IsRequired = true)]
        public string TargetCompID
        {
            get { return (string)this["targetCompID"]; }
            set { this["targetCompID"] = value; }
        }
        [ConfigurationProperty("fixVersion", IsRequired = true)]
        public ProtocolVersion Version
        {
            get
            {
                return (ProtocolVersion)this["fixVersion"];
            }
            set { this["fixVersion"] = value; }
        }

        [ConfigurationProperty("keepSequenceNumbersAfterLogout", IsRequired = true)]        
        public bool KeepSequenceNumbersAfterLogout
        {
            get { return (bool)this["keepSequenceNumbersAfterLogout"]; }
            set { this["keepSequenceNumbersAfterLogout"] = value; }
        }
}

为SessionConfiguration类创建的接口。

public interface ISessionConfiguration 
    {
        string SenderCompID { get; set; } 
        string TargetCompID { get; set; }
        ProtocolVersion Version { get; set; }
        bool SetResetSeqNumFlag { get; set; }
        string Host { get; set; }
        int Port { get; set; }
    }

单元测试类

  Class UnitTest
    {
      private Mock<ISessionConfiguration> _mockSessionConfiguration;
    [Fact]
            public void Buy_QuoteAndDeal()
            {
        _mockSessionConfiguration = new Mock<ISessionConfiguration>();
        _mockSessionConfiguration.Setup(x => x.SenderCompID).Returns("BESTINVESTLON");
                _mockSessionConfiguration.Setup(x => x.TargetCompID).Returns("WINS");
                _mockSessionConfiguration.Setup(x => x.Version).Returns(ProtocolVersion.FIX42);
                _mockSessionConfiguration.Setup(x => x.SetResetSeqNumFlag).Returns(true);
                _mockSessionConfiguration.Setup(x => x.Host).Returns("localhost");
                _mockSessionConfiguration.Setup(x => x.Port).Returns(4500);
     shareDealingEngine.Connect();
    }
    }

c#中的mock依赖不起作用

由于class属性是FixSessionConfiguration而不是ISessionConfiguration，因此mock无法工作。因为FixSessionConfiguration没有虚拟属性，所以你也不能模拟它，真的。

实际上，您应该将XYZ属性从FixSessionConfiguration更改为ISessionConfiguration -这将允许您模拟它-但是您的测试仍然无法工作，因为您还没有将mock传递到类中。您需要这样做:

var myClass = new XYZ();
myClass.Settings = _mockSessionConfiguration.Object;
// insert test code here

同样，理想情况下，设置将通过构造函数传递，但这与您面临的问题无关。
