如果一次運行一個單元測試則傳遞正常，如果運行“解決方案中的所有測試”，則為FileLoadException

Question

我正在嘗試對我的一些類進行單元測試並遇到一個問題，即單獨運行測試可以100％正常運行，但如果我批量運行它們/使用“所有測試解決方案”選項每一個測試一個我的文件失敗並顯示錯誤：

System.IO.FileLoadException was unhandled by user code
  Message=Could not load file or assembly 'Microsoft.Practices.Prism, Version=4.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
  Source=ServicesModuleTests
  FileName=Microsoft.Practices.Prism, Version=4.0.0.0, Culture=neutral, PublicKeyToken=null

我一直試圖弄清楚為什么很長一段時間，並嘗試在線搜索，但沒有發現任何人有同樣的問題。

這是我的代碼的一個簡單示例：

RegistryService文件：

public class RegistryService
{
    protected ILoggerFacadeExtended _Logger { get; set; }
    protected IConnectivityService _Connectivity { get; set; }

    [ImportingConstructor]
    public RegistryService(ILoggerFacadeExtended logger, IConnectivityService connectivity)
    {
        this._Logger = logger;
        this._Connectivity = connectivity;
    }

    public string GetRegistryPath(RegistryHive hive, string path)
    {
        string registryPath = string.Format("{0}\\{1}", GetRegistryHiveString(hive), path.Trim('\\'));
        _Logger.DebugWithFormat("Found registry path: {0}", registryPath);
        return registryPath;
    }

    private string GetRegistryHiveString(RegistryHive hive)
    {
        switch (hive)
        {
            case RegistryHive.ClassesRoot:
                return "HKEY_CLASSES_ROOT";
            case RegistryHive.CurrentConfig:
                return "HKEY_CURRENT_CONFIG";
            case RegistryHive.CurrentUser:
                return "HKEY_CURRENT_USER";
            case RegistryHive.DynData:
                return "HKEY_DYN_DATA";
            case RegistryHive.LocalMachine:
                return "HKEY_LOCAL_MACHINE";
            case RegistryHive.PerformanceData:
                return "HKEY_PERFORMANCE_DATA";
            case RegistryHive.Users:
                return "HKEY_USERS";
        }
        throw new ArgumentOutOfRangeException("hive");
    }
}

測試文件：

private RegistryService CreateMockedRegistryService()
{
    return new RegistryService(MockRepository.GenerateMock<ILoggerFacadeExtended>(), MockRepository.GenerateMock<IConnectivityService>());
}

[TestMethod()]
public void GetRegistryPathTest_ClassesRoot()
{
    RegistryService target = CreateMockedRegistryService();
    RegistryHive hive = RegistryHive.ClassesRoot;
    string path = @"Something\SomethingElse\";
    string expected = @"HKEY_CLASSES_ROOT\Something\SomethingElse";
    string actual;
    actual = target.GetRegistryPath(hive, path);
    Assert.AreEqual(expected, actual);
}

[TestMethod()]
public void GetRegistryPathTest_CurrentConfig()
{
    RegistryService target = CreateMockedRegistryService();
    RegistryHive hive = RegistryHive.CurrentConfig;
    string path = @"Something\SomethingElse\";
    string expected = @"HKEY_CURRENT_CONFIG\Something\SomethingElse";
    string actual;
    actual = target.GetRegistryPath(hive, path);
    Assert.AreEqual(expected, actual);
}

我愚蠢的代碼試圖在不占用太多空間的情況下展示我正在做的事情。 我可以一個接一個地運行這些，但是在一起運行時會收到異常。

我通過卸載其他單元測試項目然后運行測試直到它工作來解決它，顯然其中一個使用了一些較舊的棱鏡引用並且這些文件被包含而不是更新的文件，這個問題現在在我刪除並重新讀取后解決了參考文獻。
