NHibernate Configuration Error - Connection String? - asp.net

Question

I am getting this error:
------ Test started: Assembly: ECEHire.Test.dll ------
Test 'ECEHire.Test.Tests.GenerateSchema_Fixture.Can_generate_schema' failed: NHibernate.HibernateException : Format of the initialization string does not conform to specification starting at index 49.

When I try to test my NHibernate configuration file.
The configuration file is:
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
<session-factory>
<property name="dialect">NHibernate.Dialect.MsSql2005Dialect</property>
<property name="connection.connection_string">Data Source=MyServerName;initial catalog=MyDatabaseName;Integrated Security=SSPI</property>
<property name="connection.isolation">ReadCommitted</property>
<property name="proxyfactory.factory_class">NHibernate.ByteCode.LinFu.ProxyFactoryFactory, NHibernate.ByteCode.LinFu</property>
</session-factory>
</hibernate-configuration>
The test that I am running is:
<Test()> _
Public Sub Can_generate_schema()
Dim cfg = New Configuration()
cfg.Configure()
cfg.AddAssembly(GetType(Question).Assembly)
Dim exp As NHibernate.Tool.hbm2ddl.SchemaExport = New NHibernate.Tool.hbm2ddl.SchemaExport(cfg)
exp.Execute(False, True, False)
End Sub
I believe that this is a connection string error, but the connection string works as part of the web.config file for querying the database via ADO.

Answer 1

A few things to try:-
Could it be something as simple as adding a ; (semi colon) e.g. Integrated Security=SSPI;
Or try changing to Integrated Security=True;
Or drop connection.connection_string and use connection.connection_string_name
In web.config
<connectionStrings>
<add name="db" connectionString="Data Source=MyServerName;initial catalog=MyDatabaseName;Integrated Security=SSPI;"/>
</connectionStrings>
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
<session-factory>
...
<property name="connection.connection_string_name">db</property>
...
</session-factory>
</hibernate-configuration>
Edit The next thing to try is to make sure that the configuration file is being used in your test so try this:-
cfg.Configure(#"c:\hibernate.cfg.xml");
Making sure that the path IS totally correct, If this fails then put a break point at this line:-
cfg.AddAssembly(GetType(Question).Assembly)
and then add this watch cfg.Properties and make sure that the connection string is present as a key value pair
Edit2
For unit testing you would need to copy local true and get path from executing assembly OR create an app.config and use:-
<?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">
<session-factory>
<property ../>
</session-factory>
</hibernate-configuration>
</configuration>
For a web site you could do:-
cfg.Configure(HttpContext.Current.Server.MapPath("~/hibernate.cfg.xml"));
To be honest there are lots of options and this is really another question!
