如何用fluent nhibernate(schemaexport)测试生成表?在asp.net上下文

schemaexport fluent-nhibernate nhibernate asp.net

这是我第一个使用流利的hibernate的项目,我在hibernate和nhibernate方面有过一些小的经验。

所以我有我的webapp项目和大部分在网上找到的fluent nhibernate。所以我有一个实体:

namespace myproject.model
{
  public class Request
  {
    public virtual string Id { get; private set; }
    public virtual Route route { get; set; }
    public virtual int code { get; set; }

  }
}

namespace myproject.model
{
  public class Route
  {
    public virtual string Id { get; private set; }
    public virtual string client_id { get; set; }
    public virtual IList<Request> requests { get; set; }

    public Route()
    {
        requests = new List<Request>();
    }

  }

}

//Mapping are like this.will only post one
namespace myproject.mappings
{
 public class RequestMap : ClassMap<Request>
 {
    public RequestMap()
    {
        Id(x => x.Id);
        Map(x => x.short_code);
        References(x => x.route);
    }
  }
}

//NhibernateSessionPerRequest
namespace myproject.Boostrap
{
  public class NhibernateSessionPerRequest : IHttpModule
  {
    private static readonly ISessionFactory _sessionFactory;

    static NhibernateSessionPerRequest()
    {
        _sessionFactory = CreateSessionFactory();
    }

    //all others IHttpModule event and methods are here
    private static ISessionFactory CreateSessionFactory()
    {

        FluentConfiguration configuration = Fluently.Configure().Database(MsSqlConfiguration.MsSql2005.
                                                                              ConnectionString(x => x.FromConnectionStringWithKey("localdb")))
            .Mappings(m => {
                            m.FluentMappings.AddFromAssemblyOf<myproject.model.Request>();
                            m.FluentMappings.AddFromAssemblyOf<myproject.model.Route>();
                           }
                     ).ExposeConfiguration((c)=> savedConfig = c);;

        return configuration.BuildSessionFactory();
    }

  }

   private static Configuration savedConfig;

    public static void BuildSchema(NHibernate.Cfg.Configuration config)
    {
        new SchemaExport(config).Create(false, true);
    }

    public static void BuildSchema(ISession session)
    {
        var export = new SchemaExport(savedConfig);
        export.Execute(false,true,false,session.Connection,null);
    }


}

  <add name="NhibernateSessionPerRequest" type="myproject.Boostrap.NhibernateSessionPerRequest"/>

为了测试表的生成,我添加了一个测试项目(类库),并将ref添加到nunit.framework框架2.8.5和我的项目。

namespace myproject.Tests
{
  [TestFixture]
  public class CanGenerateSchemaTestSuite
  {
    [Test]
    public void CanGenarateSchema()
    {
       NhibernateSessionPerRequest.BuildSchema(NhibernateSessionPerRequest.GetCurrentSession());

     }
  }
}

测试方法总是失败,我有个例外:

CanGenerateSchemaTestSuite(1个测试),1个测试失败:子测试失败 CanGenarateSchema,失败:System.TypeInitializationException异常

谢谢你的阅读这个。谢谢

只是对另一个解决方案的模糊注释;不需要为此完全删除数据库文件;只需删除表:

.ExposeConfiguration(SetupTestDatabase)

...

private static void SetupTestDatabase(NHibernate.Cfg.Configuration config)
{
    var schema = new SchemaExport(config);
    schema.Drop(true, true);
    schema.Create(true, true);
}

这只意味着你可以在不同的数据库上运行你的测试,而不需要改变其他任何东西。

认为那是一个公认的解决办法。如果你在做测试,就这样做:

   [Test]
    public void Test_can_store_and_get_objects()
    {
        var factory = CreateSessionFactory();
        using (var s = factory.OpenSession())
        { 
             ...
        }
    }

    private static ISessionFactory CreateSessionFactory()
    {
        return Fluently.Configure().Database(SQLiteConfiguration.Standard.UsingFile("firstProject.db"))
        .Mappings(m => m.FluentMappings.AddFromAssemblyOf<Address>()) // <-- Refer to parent project
        .ExposeConfiguration(SetupTestDatabase)
        .BuildSessionFactory();
    }

这是我的一个例子。你需要使用 ExposeConfiguration SchemaExport :

class SqliteRefSessionFactoryProvider : ISessionFactoryProvider
{

    public const string SqliteRefFileName = "ref.db";

    public ISessionFactory GetSessionFactory()
    {
        return Fluently.Configure().Database(
            SQLiteConfiguration.Standard.UsingFile(SqliteRefFileName).ShowSql())
            .Mappings(m => m.FluentMappings.AddFromAssemblyOf<SsoToken>())
            .ExposeConfiguration(BuildSchema)
            .BuildSessionFactory();
    }

    private static void BuildSchema(NHibernate.Cfg.Configuration configuration) 
    {
        if (File.Exists(SqliteRefFileName))
            File.Delete(SqliteRefFileName);

        new SchemaExport(configuration)
          .Create(false, true);
    }
}
