起订量定制 IIidentity

我创建了一个自定义 RoleProvider（标准 Web 表单，无 MVC），我想测试它。提供程序本身与 IIdentity 的自定义实现集成（带有一些附加属性）。

我现在有这个：

var user = new Mock<IPrincipal>();
var identity = new Mock<CustomIdentity>();

user.Setup(ctx => ctx.Identity).Returns(identity.Object);
identity.SetupGet(id => id.IsAuthenticated).Returns(true);
identity.SetupGet(id => id.LoginName).Returns("test");

// IsAuthenticated is the implementation of the IIdentity interface and LoginName

但是，当我在 VS2008 中运行此测试时，我收到以下错误消息：

Invalid setup on a non-overridable member: id => id.IsAuthenticated

为什么会发生这种情况？最重要的是，我需要做什么来解决这个问题？

I created a custom RoleProvider (standard webforms, no mvc) and I would like to test it. The provider itself integrates with a custom implementation of IIdentity (with some added properties).

I have this at the moment:

var user = new Mock<IPrincipal>();
var identity = new Mock<CustomIdentity>();

user.Setup(ctx => ctx.Identity).Returns(identity.Object);
identity.SetupGet(id => id.IsAuthenticated).Returns(true);
identity.SetupGet(id => id.LoginName).Returns("test");

// IsAuthenticated is the implementation of the IIdentity interface and LoginName

However when I run this test in VS2008 then I get the following error message:

Invalid setup on a non-overridable member: id => id.IsAuthenticated

Why is this happening? And most important, what do I need to do to solve it?

Grz, Kris.

您应该模拟 IIdentity（而不是 CustomIdentity - 仅当您模拟的变量在接口中声明时才可能）或将使用的变量声明为虚拟变量。

要标记为虚拟，请执行以下操作：在具体类 CustomIdentity 中，使用

public virtual bool isAuthenticated { get; set; }

而不是

public bool isAuthenticated { get; set; }

Moq 和其他免费模拟框架不允许您模拟具体类类型的成员和方法，除非它们被标记为虚拟。

最后，您可以自己手动创建模拟。您可以将 CustomIdentity 继承到测试类，该类将返回您想要的值。类似于：

internal class CustomIdentityTestClass : CustomIdentity
{
    public new bool isAuthenticated
    {
        get
        {
            return true;
        }
    }

    public new string LoginName
    {
        get
        {
            return "test";
        }
    }

}

此类仅用于测试，作为您的 CustomIdentity 的模拟。

回答评论中的问题。

You should mock IIdentity (instead of CustomIdentity - only possible if the variables you are mocking are declared in the interface) or declare the used variables as virtual.

To mark as virtual, do this: In your concrete class CustomIdentity, use

public virtual bool isAuthenticated { get; set; }

instead of

public bool isAuthenticated { get; set; }

Moq and other free mocking frameworks doesn't let you mock members and methods of concrete class types, unless they are marked virtual.

Finally, you could create the mock yourself manually. You could inherit CustomIdentity to a test class, which would return the values as you wanted. Something like:

internal class CustomIdentityTestClass : CustomIdentity
{
    public new bool isAuthenticated
    {
        get
        {
            return true;
        }
    }

    public new string LoginName
    {
        get
        {
            return "test";
        }
    }

}

This class would be only used in testing, as a mock for your CustomIdentity.
