我正在尝试为我的 NHibernate 数据访问层实现单元测试。我从网上找到的一个例子( http://blogs.hibernatingrhinos.com/nhibernate/archive/2008/04/01/your-first-nhibernate-based-application.aspx)中得出的第一个测试是只是尝试使用我的域类/映射重新创建数据库。我已经能够让这个示例在 C# 中工作(产品表是在数据库中创建的),但是当我在 VB.NET 中实现它时却没有。
我有两个项目,Todd.Core(包含 Product 类和 Product.hbm.xml 映射)和 Todd.Core.Test(包含 Test Fixture 和 NHibernate 配置)。当我尝试使用 MBUnit GUI 运行此测试时,我收到此消息(第 10 行是对 .Configure 方法的调用):
Message: Could not compile the mapping document: Todd.Core.Product.hbm.xml

任何想法表示赞赏。下面是我的代码......
我的产品类别:
Namespace Todd.Core
Public Class Product
Private _id As Guid
Private _name As String
Private _category As String
Private _discontinued As Boolean
Public Overridable Property Id() As Guid
Get
Return _id
End Get
Set(ByVal value As Guid)
_id = value
End Set
End Property
Public Overridable Property Name() As String
Get
Return _name
End Get
Set(ByVal value As String)
_name = value
End Set
End Property
Public Overridable Property Category() As String
Get
Return _category
End Get
Set(ByVal value As String)
_category = value
End Set
End Property
Public Overridable Property Discontinued() As Boolean
Get
Return _discontinued
End Get
Set(ByVal value As Boolean)
_discontinued = value
End Set
End Property
End Class
End Namespace
我的 Product.hbm.xml 文件:
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2">
<class name="Todd.Core.Product, Todd.Core" table="Product">
<id name="Id">
<generator class="guid" />
</id>
<property name="Name" />
<property name="Category" />
<property name="Discontinued" />
</class>
</hibernate-mapping>
我的测试夹具:
Imports MbUnit.Framework
Imports Todd.Core
<TestFixture()> _
Public Class GenerateSchema_Fixture
<Test()> _
Public Sub Can_generate_schema()
Dim cfg As New NHibernate.Cfg.Configuration
cfg.Configure()
cfg.AddAssembly(GetType(Todd.Core.Product).Assembly)
Dim exp As NHibernate.Tool.hbm2ddl.SchemaExport = New NHibernate.Tool.hbm2ddl.SchemaExport(cfg)
exp.Execute(True, True, False, True)
End Sub
End Class
我的 app.config(来自测试项目):
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<section name="hibernate-configuration"
type="NHibernate.Cfg.ConfigurationSectionHandler, NHibernate" />
</configSections>
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">

<property name="dialect">NHibernate.Dialect.MsSql2005Dialect</property>
<property name="show_sql">true</property>
