在运行Fitnesse测试时映射组件时找不到程序集FluentHibernate

Question

我遇到了一个非常奇怪的问题。我有几个正在工作的Fitnesse测试，它们将数据插入数据库，然后测试我的完整MVC应用程序堆栈。

当我试图将2个组件属性映射添加到实体映射时，我收到一个错误，说"找不到程序集'FluentHibernate…'，这似乎有点神秘。

所有这些都是通过Fitnesse运行的，所以这可能是Fitnesse如何加载依赖项的问题。。。不过，我不知道是否能确定。我唯一知道的是，在添加2个"组件"映射之前，此代码运行良好。最重要的是，当这些代码通过普通的web应用程序运行时，这些映射运行良好（所以我知道"组件"映射和SessionFactory类在测试项目之外工作）。

有人知道我为什么会收到错误消息吗？请让我知道，如果有任何其他代码，我需要张贴。非常感谢您的帮助！

DLL版本：

• NHibernate-3.3.1.4000
• FluentHibernate-1.3.0.733
• Fitnesse-v20111026
• fitSharp-2.2.4498.25493

这是我的实体：

// namespace Reporting.Domain
public class Holdings
{
    public virtual int HoldingsId { get; set; }
    public virtual DateTime AsOfDate { get; set; }
    public virtual string Portfolio { get; set; }
    // need to add these next 2 properties!
    public virtual Balances PriorPeriod { get; set; }
    public virtual Balances CurrentPeriod { get; set; }
}

我的映射文件：

// namespace Reporting.Infrastructure
public sealed class HoldingsMap : ClassMap<Holdings>
{
    public HoldingsMap()
    {
        Id(x => x.HoldingsId).GeneratedBy.Identity();
        Map(x => x.AsOfDate).Not.Nullable();
        Map(x => x.Portfolio).Not.Nullable();
        // adding these lines eventually leads to the error
        Component(x=> x.PriorPeriod).ColumnPrefix("Prior");
        Component(x=> x.CurrentPeriod).ColumnPrefix("Current");
    }
}

我的SessionFactory（调用BuildSessionFactory时发生错误）：

// namespace Reporting.Infrastructure
public class SessionFactory
{
    public ISessionFactory CreateSession(Action<Configuration> configurationFunction)
    {
        return CreateConfiguration().ExposeConfiguration(c => {}).BuildSessionFactory();
    }
    private FluentConfiguration CreateConfiguration()
    {
        var connectionString = "...";
        var msSqlConfiguration = MsSqlConfiguration.MsSql2008.ConnectionString(connectionString);
        var database = Fluently.Configure().Database(msSqlConfiguration);
        return database.Mappings(m => m.FluentMappings.AddFromAssemblyOf<SessionFactory>().Conventions.Add(ForeignKey.EndsWith("Id")));
    }
}

我得到这个堆栈跟踪：

FWIW，这就是我如何使用Fitnesse测试项目中的会话工厂：

// namespace Reporting.FitnesseTests
public class Database
{
    public static ISession Session { get; private set; }
    public static void Setup()
    {
        Session = new SessionFactory().CreateSession().OpenSession();
    }
}

我的Fitnesse Classpath是：

!path ..Reporting.FitnesseTestsbinDebugReporting.FitnesseTests.dll

尝试将测试要查找的DLL与fitsharp Runner.exe放在同一文件夹中。我遇到的一个问题是，在app.config中定义的.NET运行时依赖项是从执行进程的目录中解析的，在本例中，该目录可能是fitsharp所在的目录。显然有一种方法可以使用fitsharp套件配置文件来改变这种行为，但我还没能成功地让它工作(http://fitsharp.github.com/FitSharp/SuiteConfigurationFile.html)。
