单元测试一个类声明为朋友(内部) [英] Unit test a class declared friend (internal)
问题描述
在我的一些测试帮助程序代码中，我有一个名为FakeDbSet(Of T)的IDbSet(Of T)实现，该实现可在没有实际数据库的情况下模拟许多EF行为.我有一个声明为Friend的类，因为我想强制所有代码像IDbSet(Of T)那样与之交互.在内部(即，在我的Testing程序集中)，我访问了我想测试的课程的许多公共成员.
In some of my test helper code, I have a IDbSet(Of T) implementation called FakeDbSet(Of T) that mocks a lot of EF behavior without an actual database. I have the class declared Friend because I want to force all code to interact with it like an IDbSet(Of T). Internally (ie within my Testing assembly), I access a lot of the public members of the class which I want to be able to test.
问题是，我将单元测试保存在单独的程序集中Test.Unit，这意味着它们无法访问我的内部实现！我知道我可以通过反射来解决这个问题，但是那很快就会变得麻烦和混乱.有什么更好的方法来设置我的项目来避免此问题?
The problem is, I keep my unit tests in a separate assembly Test.Unit which means they cannot access my internal implementation! I know I can get around this with reflection, but that gets cumbersome and messy very quickly. Is there any better way to set up my project to avoid this problem?
推荐答案
将其添加到AssemblyInfo.cs文件中:
Add this to your AssemblyInfo.cs file:
[assembly:InternalsVisibleTo("YourOtherAssembly")]
这将使您的内部程序集对YourOtherAssembly可见.但是，您应该真正考虑是否需要internal.编写测试时，请尝试着重于public部件.
This will make your internal assemblies visible to YourOtherAssembly. However, you should really consider if you need to have it internal. When writing tests try focusing on your public parts.
