Question

i’m building some basic crud methods for my fluently mapped entities.

i just wanna know if there is a simple way to make the transaction to perform a rollback when i’m running the cud test methods ?

the code that being tested perform the commit inside

here is a create sample:

 public int? Create(IIdentifiable entity)
    {
        int? newId = null;
        using (ISession session = SessionFactoryProvider.NewSession)
        using (ITransaction transaction = session.BeginTransaction())
        {
            object newObj = session.Save(entity);
            newId = (int?)newObj;
            transaction.Commit();
        }

        return (int?)newId;
    }

If you’re using xUnit.net, there’s an AutoRollback attribute in the contrib project. If you’re open to using System.Transactions then you can create a new transaction before the session.Open() and session should autoenlist (unless you’ve set ado.net to not autoenlist). Then just abandon at the end.

I did something similar to this a (long) while ago:

public class TransactionalTest
{
    public TransactionalTest()
    {
        Transaction.Current = new CommittableTransaction();
    }

    ~TransactionalTest()
    {
        if (Transaction.Current != null &&
            Transaction.Current.TransactionInformation.Status !=
            TransactionStatus.Committed)
        {
            Transaction.Current.Rollback();
        }
    }
}

Then just have your test extend TransactionalTest. But, I think NUnit, MbUnit and xUnit.net all support transactional tests out of the box or with a contrib project.
