最小起订量IIdentity [英] Moq custom IIdentity

问题描述

我创建了一个自定义RoleProvider(标准Web表单，没有mvc)，我想对其进行测试.提供程序本身与IIdentity的自定义实现集成(具有一些附加属性).

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).

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，会收到以下错误消息:

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

在不可覆盖的成员上的无效设置:id => id.IsAuthenticated

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

为什么会这样?最重要的是，我需要怎么做才能解决它?

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

格里斯，克里斯.

推荐答案

您应该模拟IIdentity(而不是CustomIdentity-仅在要模拟的变量在接口中声明的情况下才可以)或将使用的变量声明为虚拟.

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.

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

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

public virtual bool isAuthenticated { get; set; }

代替

public bool isAuthenticated { get; set; }

---

Moq和其他免费的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的.

---

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

最后，您可以自己手动创建模拟.您可以将CustomIdentity继承到测试类，该类将根据需要返回值.像这样:

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";
        }
    }

}

此类仅用于测试，作为您的CustomIdentity的模拟.

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