测试一个类是否有属性?

Test if a class has an attribute?(测试一个类是否有属性?)

问题描述

我正在尝试进行一些 Test-First 开发，并且正在尝试验证我的类是否标有属性:

I'm trying to do a little Test-First development, and I'm trying to verify that my classes are marked with an attribute:

[SubControllerActionToViewDataAttribute]
public class ScheduleController : Controller

我如何对类分配了该属性进行单元测试?

How do I unit test that the class has that attribute assigned to it?

推荐答案

检查一下

Attribute.GetCustomAttribute(typeof(ScheduleController),
    typeof(SubControllerActionToViewDataAttribute))

不为空(Assert.IsNotNull 或类似)

(我使用它而不是 IsDefined 的原因是大多数时候我也想验证属性的某些属性......)

(the reason I use this rather than IsDefined is that most times I want to validate some properties of the attribute too....)
