Question

I get the following error when running any NUnit integration test

- Assembly setup complete -
Beginning Processing of Tests -
Test 'PXL.IntegrationTests.EventDaoTests.deleteEvent' failed: Spring.Objects.Factory.ObjectCreationException : Error creating object with name 'NHibernateSessionFactory' defined in 'assembly [PXL.Dao.NHibernate, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null], resource [PXL.Dao.NHibernate.Dao.Dao.xml] line 18' : Initialization of object failed : Association references unmapped class: PXL.Domain.TBEvent

Assembly TearDown

0 passed, 1 failed, 0 skipped, took 4.67 seconds (NUnit 2.5.5).

The line of code that the error refers to is the NHibernate Dao Configuration 1st line.

<!-- NHibernate Configuration -->
<object id="NHibernateSessionFactory" type="Spring.Data.NHibernate.LocalSessionFactoryObject, Spring.Data.NHibernate21" scope="application">
    <property name="DbProvider" ref="DbProvider"/>
    <property name="MappingAssemblies">
        <list>
            <value>PXL.Dao.NHibernate</value>
        </list>
    </property>
    <property name="HibernateProperties">
        <dictionary>
            <entry key="hibernate.connection.provider" value="NHibernate.Connection.DriverConnectionProvider"/>
            <entry key="dialect" value="NHibernate.Dialect.MsSql2008Dialect"/>
            <entry key="connection.driver_class" value="NHibernate.Driver.SqlClientDriver"/>
        </dictionary>
    </property>

    <!-- provides integation with Spring's declarative transaction management features -->
    <property name="ExposeTransactionAwareSessionFactory" value="true" />
</object>

The missing file that it refers to “Association references unmapped class: PXL.Domain.TBEvent” does exist and as far as I can see there is nothing missing, the mapping file has no errors in it and there is a cs file for it to map to and all the interfaces exist and the row in the dao which refers to it also exists.

<object id="TBEventDao" type="PXL.Dao.NHibernate.HibernateTBEventDao, PXL.Dao.NHibernate">
    <property name="SessionFactory" ref="NHibernateSessionFactory"/>
</object>

I know this is something simple, wonder if anyone here can give me some insight.

Make sure the Build Action of your mapping xml file is set to Embedded Resource and that the extension is .hmb.xml.
