VS2017 .Net标准库中的单元测试内部方法 [英] Unit testing internal methods in VS2017 .Net Standard library

问题描述

我目前正在通过创建.Net Standard 1.6库来使用最新的Visual Studio 2017 Release Candidate。我正在使用xUnit来对我的代码进行单元测试，并且想知道是否仍然可以在VS2017中测试内部方法。

I am currently playing around with the latest Visual Studio 2017 Release Candidate by creating a .Net Standard 1.6 library. I am using xUnit to unit test my code and was wondering if you can still testing internal methods in VS2017.

我记得您可以在中全部使用AssemblyInfo.cs类VS2015，它将使指定的项目能够查看内部方法

I remember that you could all a line AssemblyInfo.cs class in VS2015 that would enable specified projects to see internal methods

[assembly:InternalsVisibleTo("MyTests")]

由于VS2017 .Net Standard项目中没有AssemblyInfo.cs类，我想知道您是否仍然可以对内部方法进行单元测试？ / p>

As there is no AssemblyInfo.cs class in VS2017 .Net Standard projects I was wondering if you can still unit test internal methods?

推荐答案

根据 .NET文档 InternalsVisibleToAttribute ：

该属性在程序集级别应用。这意味着它可以包含在源代码文件的开头，也可以包含在Visual Studio项目的AssemblyInfo文件中。

The attribute is applied at the assembly level. This means that it can be included at the beginning of a source code file, or it can be included in the AssemblyInfo file in a Visual Studio project.

换句话说，您可以简单地将其放在自己的任意命名的.cs文件中，并且应该可以正常工作：

In other words, you can simply place it in your own arbitrarily named .cs file, and it should work fine:

// some .cs file included in your project
using System.Runtime.CompilerServices;
[assembly:InternalsVisibleTo("MyTests")]
