c# - 单元测试错误，无法加载文件或程序集

Question

我对我的 Controller 进行了单元测试(大约 36 个)。当我运行它们时。我在所有测试中都遇到了同样的错误

Unable to get type AdminPortal.Tests.Controller_Test.OwnedModuleControllerTest. Error: System.IO.FileLoadException: Could not load file or assembly 'AdminPortal.Tests, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. Signature missing argument. (Exception from HRESULT: 0x801312E3)
File name: 'AdminPortal.Tests, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' ---> System.Runtime.InteropServices.COMException (0x801312E3): Signature missing argument. (Exception from HRESULT: 0x801312E3)

   at System.Reflection.Assembly.LoadFrom(String assemblyFile)
   at Microsoft.VisualStudio.TestPlatform.MSTestFramework.TypeCache.LoadType(String typeName, String assemblyName).

这是我的assemblyinfo类

using System.Reflection;
using System.Runtime.InteropServices;

// General Information about an assembly is controlled through the following 
// set of attributes. Change these attribute values to modify the information
// associated with an assembly.
[assembly: AssemblyTitle("AdminPortal.Tests")]
[assembly: AssemblyDescription("")]
[assembly: AssemblyConfiguration("")]
[assembly: AssemblyCompany("")]
[assembly: AssemblyProduct("AdminPortal.Tests")]
[assembly: AssemblyCopyright("Copyright ©  2013")]
[assembly: AssemblyTrademark("")]
[assembly: AssemblyCulture("")]

// Setting ComVisible to false makes the types in this assembly not visible 
// to COM components.  If you need to access a type in this assembly from 
// COM, set the ComVisible attribute to true on that type.
[assembly: ComVisible(false)]

// The following GUID is for the ID of the typelib if this project is exposed to COM
[assembly: Guid("0412bc0c-30bc-4e0c-9a8d-bcbcd7876702")]

// Version information for an assembly consists of the following four values:
//
//      Major Version
//      Minor Version 
//      Build Number
//      Revision
//
// You can specify all the values or you can default the Revision and Build Numbers 
// by using the '*' as shown below:
[assembly: AssemblyVersion("1.0.0.0")]
[assembly: AssemblyFileVersion("1.0.0.0")]

Answer 1

我花了一段时间才找到这个问题。问题是我的测试项目隐式引用了另一个项目中的类，而我的测试项目中没有明确引用该类。一旦我将引用(对隐式引用的项目)添加到我的测试项目并重新构建，测试就会再次开始填充到测试资源管理器中。 @wal 发布的链接是让我朝那个方向思考的提示。从帖子来看，这似乎是 Visual Studio/Rhino Mocks 问题。

when using generics and/or delegation, make sure all types implicitly referenced by your code are explicitly referenced in the project References.
