I cannot create a failing test, here is my attempt:
[Test]
public void Can_roll_back_transaction()
{
var tx = new TransactionScope();
using (var s = sessions.OpenSession())
{
new ForceEscalationToDistributedTx(true);//will
rollback tx
s.Save(new Person
{
CreatedAt = DateTime.Today
});
tx.Complete();
}
try
{
tx.Dispose();
Assert.Fail("Expected tx abort");
}
catch (TransactionAbortedException)
{
//expected
}
}
