C#“内部"进行单元测试时的访问修饰符 [英] C# "internal" access modifier when doing unit testing

问题描述

我是单元测试的新手，我想知道是否应该开始使用更多的 internal 访问修饰符.我知道如果我们使用 internal 并设置程序集变量 InternalsVisibleTo，我们可以测试我们不想从测试项目中声明为 public 的函数.这让我觉得我应该总是使用 internal 因为至少每个项目(应该?)都有自己的测试项目.你们能告诉我为什么我不应该这样做吗?我什么时候应该使用 private?

I'm new to unit testing and I'm trying to figure out if I should start using more of internal access modifier. I know that if we use internal and set the assembly variable InternalsVisibleTo, we can test functions that we don't want to declare public from the testing project. This makes me think that I should just always use internal because at least each project (should?) have its own testing project. Can you guys tell me why I shouldn't do this? When should I use private?

推荐答案

内部类需要测试，有一个assemby属性:

Internal classes need to be tested and there is an assemby attribute:

using System.Runtime.CompilerServices;

[assembly:InternalsVisibleTo("MyTests")]

将此添加到项目信息文件中，例如PropertiesAssemblyInfo.cs.

Add this to the project info file, e.g. PropertiesAssemblyInfo.cs.
