I am writing tests for my logic layer and I am running into an issue
that I have no idea how to debug and I can't find much guidance on the
intertubes. Here is my output from MbUnit.
============
NHibernate: SELECT cwtratingg0_.Id as Id17_0_, cwtratingg0_.Name as
Name17_0_, cwtratingg0_.UserAdded as UserAdded17_0_,
cwtratingg0_.DateAdded as DateAdded17_0_, cwtratingg0_.UserEdited as
UserEdited17_0_, cwtratingg0_.DateEdited as DateEdited17_0_ FROM
dbo.tblCWTRatingGroups cwtratingg0_ WHERE cwtratingg0_....@p0; @p0 =
'100'

============
Here is my unit test:
============
[Test]
[DependsOn(typeof(CWTRatingGroupTests),
"CanGetCWTRatingGroupByName")]
[DependsOn("CanAddCWTRatingGroup")]
public void CanModifyCWTRatingGroup()
{
string newGroupName = "Logic Modified Group";
CWTRatingGroup ratingGroup =
_Provider.GetCWTRatingGroupById(100);
_RatingLogic.ModifyCWTRatingGroup(newGroupName,
ratingGroup.Id, 1);
ratingGroup = _Provider.GetCWTRatingGroupByName
(newGroupName);
Assert.IsNotNull(ratingGroup);
Assert.AreEqual(1, ratingGroup.UserEdited.Id);
}
===========
Here is my logic code:
===========
public void ModifyCWTRatingGroup(string name, int
ratingGroupId, int userEditedId)
{
CWTRatingGroup ratingGroup = provider.GetCWTRatingGroupById
(ratingGroupId);
ratingGroup.Name = name;
ratingGroup.UserEdited = provider.GetUserById
(userEditedId);
provider.ModifyCWTRatingGroup(ratingGroup);
}
===========
Finally my data layer
===========
public void ModifyCWTRatingGroup(CWTRatingGroup ratingGroup)
{
if (ratingGroup.UserEdited == null)
throw new ArgumentException("UserEdited may not be
null");
try
{
ratingGroup.DateEdited = DateTime.Now;
session.Transaction.Begin();
session.Update(ratingGroup);
session.Flush();
session.Transaction.Commit();
}
catch (Exception)
{
session.Transaction.Rollback();
throw;
}
}
==========
I have stepped through this and everything looks kosher. ratingGroup
in the DAL has all the required fields populated with valid values.
It's Id is definitely populated and is not null. The exception is
thrown when Flush() is called.
I hope someone has an idea because this code works in another test it
was when I added the logic layer in the middle that this code began to
throw an exception.
Thank you in advance,
Josh Rogers
