c# - Moq 具有另一个 moq 的具体类的属性

Question

我正在尝试创建一个具体类的模拟，并用另一个模拟来模拟它的一个属性。

public class MyClass
{
  public virtual IAdapter Adapter {get; internal set;}
}

测试...

var adapter = new Mock<IAdapter>();
adapter.Setup(a => a.WaitForDigit()).Returns(1);
var myClass = new Mock<MyClass>();
myClass.Setup(c => c.Adapter).Returns(adapter.Object); //throws exception

它抛出以下异常:System.ArgumentException: 常量与定义的类型不匹配

我该如何解决？

编辑:

我已经改变了设计，即使那样它仍然抛出同样的异常

public class MyClass
{
  public virtual IAdapter Adapter {get;set;}
  public MyClass(IAdapter adapter)
  {
    Adapter = adapter;
  }
}

var adapter = new Mock<IAdapter>();
adapter.Setup(a => a.WaitForDigit()).Returns(1);
var myClass = new MyClass(adapter.Object); //throws exception

System.ArgumentException: Constant does not match the defined type.

事实证明这与 Moq 无关。据报道，这是一个 CaSTLe.Core 错误 here .

为了解决这个问题，我安装了 CaSTLe.Core v4.0 beta 包。
