单元测试使用实际的类，而不是类的副本 [英] unit test to use actual classes and not copies of classes

问题描述

我目前在一个更大的系统软件创造了一些类单元测试/模块，采用Visual Studio 2008中的类的源文件都存储在一个存储库。当然，每当我将测试这些类，我将不得不选择将其包含在项目中的添加现有项，使我不得不说我会得到测试类的精确副本。这使得VS2008做出自己的类副本。但事实是，需求突然都在改变我必须用实际的类本身，而不是它们的副本（比如，放在测试项目的引用），这样，每当类将被编辑/修改/更新，单元测试一定会失败。我似乎无法找到任何选项，其中我的地方，在测试项目实际类的引用，并从那里，我想创建单元测试。有没有什么办法，其中我可以测试实际的类本身？

I'm currently creating unit tests for some classes/module in a much bigger system software, using Visual Studio 2008. The source files of the classes are stored in one repository. Of course, whenever I would test these classes, I would have to include them in the project by selecting the "Add Existing Item" so that I would have an exact copy of the class that I would get to test. This makes VS2008 make its own copy of the class. But the thing is, requirements suddenly have changed in that I have to use the actual classes themselves, and not copies of them (like, put a reference in the test project), so that whenever the classes would be edited/changed/updated, the unit test would surely fail. I can't seem to find any options wherein I'd place a reference to the actual classes in the test project, and from there, I'd create the unit test. Is there any way wherein I could test the actual classes themselves?

推荐答案

关键是将文件添加为纽带（东西就像一个快捷方式）：

The key is to add the files as a link (something like a shortcut):

添加现有项>添加链接

见截图：

这样的Visual Studio不会让副本这些文件，如果原始出处改变他们，他们也将在您的解决方案进行修改。

That way Visual Studio won't make a copy of the files, and if you change them in the original source, they will also be modified in your Solution.
