Question

我的Windows Phone 7项目中的一个NUnit测试因以下错误而失败：

Error   4   Test 'MyProject.Tests.Unit.Service.TaskServiceTests.Save_CallsWebService_WhenCalledWithTaskAndSession' failed: System.IO.FileNotFoundException : Could not load file or assembly 'System.Runtime.Serialization, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e' or one of its dependencies. The system cannot find the file specified.

问题是由我编写的扩展方法引起的，该方法是使用JSON.NET将POCO序列化为JSON。似乎JSON.NET依赖于System.Runtime.Serialization。

我已经尝试将JSON.NET和System.Runtime.Serialization引用添加到我的测试项目中，但这并没有解决问题。

我正在测试的程序集使用RestSharp，而RestSharp又依赖于JSON.NET。我尝试将System.Runtime.Serialization的引用直接添加到正在测试的程序集中，但也失败了。

有什么建议吗？

更新：我正在尝试按照以下评论中的建议跟踪文件，但Filemon已经停用。它的替换，Process Explorer，没有帮助，因为它似乎只显示devenv.exe进程当前保持打开的文件。搜索有问题的文件的引用只会产生两个不相关的引用。有没有办法看到我的测试运行的录音，所以我可以告诉它在哪里寻找.dll？

更新2：感谢您的建议。我通过使用Nuget将RestSharp和JSON.NET引用直接添加到单元测试项目来解决IO问题。现在我收到以下错误：

Error   5   Test 'MyProject.Tests.Unit.Service.TaskServiceTests.Save_CallsWebService_WhenCalledWithTaskAndSession' failed: System.InvalidProgramException : Common Language Runtime detected an invalid program.

在此网站上搜索主要返回对TFS开发的引用。大。

Answer 1

为单元测试项目的WP7项目引用中的所有系统程序集设置“Copy Local”为true。我们在项目中使用Netwonsoft的Json和NUnit，没有任何问题。
