如何使用 NUnit 模拟属性？

---

注意:我找到了this peripheral mocking answer非常有用，并将其重新用作此处的独特问答条目，供其他人查找。

也欢迎其他答案。

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.

Answer 1

在以下示例中模拟 Names 属性...

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

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

属性的 NUnit 模拟解决方案

using NUnit.Mocks;

在 NUnit 中，PropertyName 可以使用模拟库的Expect*(..) 方法如下:

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));

因此，在我们顶部的特定代码示例中，.Names 属性被模拟为 get_Names 或 set_Names。

等等

This blog post考虑到 NUnit 似乎只为目标方法提供模拟方法，提供了额外的见解:

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