Question

我想要一个简单的单元测试来验证我的单位配置xml中的所有类型是否有效

[TestMethod]
[TestCategory("IntegrationTest")]
[DeploymentItem(@"..\..\..\App\Unity.config", @"MyApp")]
public void VerifyTypeNamesForMyAppUnityConfig()
{       
   var fileMap = new ExeConfigurationFileMap { 
      ExeConfigFilename = @"MyApp\Unity.config" 
   };
   var configuration = ConfigurationManager
       .OpenMappedExeConfiguration(fileMap, ConfigurationUserLevel.None);
   var unitySection = (UnityConfigurationSection)configuration.GetSection("unity");
   var container = new UnityContainer();

   container.LoadConfiguration(unitySection);
}

Unity.config在执行App时有效。

我引用了测试项目中的所有程序集

我得到了这个例外

Test Name:  VerifyTypeNamesForMyAppUnityConfig
Test FullName:  MyApp.Test.UnityTests.VerifyTypeNamesForMyAppUnityConfig
Test Source:    c:\SourceControl\MyAppMerge\MyApp.Test\UnityTests.cs : line 47
Test Outcome:   Failed
Test Duration:  0:00:00.5187389

Result Message: 
Test method MyApp.Test.UnityTests.VerifyTypeNamesForMyAppUnityConfig threw exception: 
System.InvalidOperationException: The type name or alias MyApp.Services.Attachments.AttachmentService, MyApp.Services.Attachments could not be resolved. Please check your configuration file and verify this type name.

   at MyApp.Test.UnityTests.VerifyTypeNamesForMyAppUnityConfig() in c:\SourceControl\MyAppMerge\MyApp.Test\UnityTests.cs:line 61

测试通过如果我进行此更改

var WTF = new List<AttachmentService>();
container.LoadConfiguration(unitySection);

但这次失败就像这样

//var WTF = new List<AttachmentService>();
container.LoadConfiguration(unitySection);

为什么？

我有数百个统一配置。大多数都有效。只有少数几个类需要这个小技巧。我不知道这些少数类/程序集有什么不同。唯一的相似之处是程序集中只有1到3个类（非常小的程序集）

Answer 1

我检查了TestResults文件夹（如Alexei建议的那样）并且它没有程序集！即使它设置为Copy Local = True。

看来MSTest使用反射来确定复制到TestResults文件夹的程序集。

有关详细信息，请参阅此SO TFS not deploying referenced assembly to test dir when on build server

你必须在程序集中引用一些东西（类似于上面的技巧）

OR

获取所有的dll：

[DeploymentItem(@".")]

要获得一个dll：

[DeploymentItem(@"YourAssembly.dll")]

注意：您将获得一些＆＃34;该过程无法访问该文件＆＃34;错误，但不要担心它会复制未使用的错误。（这是问题！）
