如何才能获得使用微软正版正货基类的垫片？ [英] How do I get shims for base classes using Microsoft Fakes?

问题描述

class Parent{
   public string Name{ get; set; }
}

class Child :Parent{
   public string  address{ get; set; }
}

[TestClass]
class TestClass{
   [TestMethod]
   public void TestMethod()
   {
      var c = new Fakes.Child();
      c.addressGet = "foo"; // I can see that
      c.NameGet = "bar"; // This DOES NOT exists
   }
}

如何设置名上面的代码示例中？

How can I set the "name" in the above code sample?

推荐答案

您必须声明它的基类。最简单的方法是调用基类的AllInstances属性：

You'll have to declare it on the base class. The easiest way is to call the base class its AllInstances property:

[TestClass]
public class UnitTest1
{
    [TestMethod]
    public void TestMethod1()
    {
        ClassLibrary1.Child myChild = new ClassLibrary1.Child();

        using (ShimsContext.Create())
        {
            ClassLibrary1.Fakes.ShimChild.AllInstances.addressGet = (instance) => "foo";
            ClassLibrary1.Fakes.ShimParent.AllInstances.NameGet = (instance) => "bar";

            Assert.AreEqual("foo", myChild.address);
            Assert.AreEqual("bar", myChild.Name);
        }

    }
}

也总是尝试添加ShimsContext以确保您的垫片的正确的清洗。否则，你的其他单元测试也将获得返回的值，你以前声明。在ShimsContext
