其他答案欢迎了。

  

NUnit的-讨论注：    NUnit的嘲弄是在一个周末创建   作为玩具模拟实现[...]我开始认为这是一个错误，因为你是远   从第一人成为依赖它。的

解决方案

要嘲笑的姓名的下面的示例属性...

 接口IVIEW {
    名单＆LT;字符串＆GT;名称{获得;组;}
}

公共类presenter {
    公开名单＆LT;字符串＆GT; GetNames（IVIEW视图）{
       返回view.Names;
    }
}
 

NUnit的模拟解决方案的房产

 使用NUnit.Mocks;
 

在NUnit的一个的属性名的可以用轻慢的 get_PropertyName 以嘲弄get访问和 set_PropertyName 以嘲笑set访问，使用模拟图书馆期待*（..）方法，像这样：

 列表名称=新的列表{测试，测试1};
DynamicMock mockView =新DynamicMock（typeof运算（IVIEW））;

mockView.ExpectAndReturn（get_Names，名称）;

IVIEW视图=（IVIEW）mockView.MockInstance;
Assert.AreEqual（姓名，presenter.GetNames（视图））;
 

因此​​，在我国特定的$ C顶部$ C样品中， .Names 的属性被嘲笑为任何 get_Names 或 set_Names 。

NOTE: I found this peripheral mocking answer to be extremely useful and repurposed it as a distinct question and answer entry here for others to find.

Other answers welcome too.

NUnit-Discuss Note: NUnit Mocks was created over a weekend as a toy mock implementation [...] I'm beginning to think that was a mistake, because you are far from the first person to become reliant on it.

解决方案

To mock the Names property in the following example...

Interface IView {    
    List<string> Names {get; set;} 
}

public class Presenter {    
    public List<string> GetNames(IView view)    {
       return view.Names;    
    } 
}

NUnit Mock Solution for a Property

using NUnit.Mocks;

In NUnit a PropertyName can be mocked with get_PropertyName to mock the get accessor and set_PropertyName to mock the set accessor, using the mock library's Expect*(..) methods like so:

List names = new List {"Test", "Test1"};
DynamicMock mockView = new DynamicMock(typeof(IView));

mockView.ExpectAndReturn("get_Names", names);

IView view = (IView)mockView.MockInstance;
Assert.AreEqual(names, presenter.GetNames(view));

Therefore, in our specific code sample at the top, the .Names property is mocked as either get_Names or set_Names.

Etc.

This blog post provides additional insight considering NUnit seemingly provides mock methods to only target methods:

I started thinking about it and realized that Property getters and setters are just treated as speciallly named methods under the covers
