Do the following two tests not do what you want?
public void TestExistingSessionUsesExistingTransaction()
{
// Arrange
var session = MockRepository.GenerateMock<ISession>();
var sut = new Sut(session);
sut.HasExistingSession = true;
// Act
sut.TransactionSave("foo");
// Assert
session.AssertWasCalled(x => x.Save("foo"));
session.AssertWasNotCalled(x => x.BeginTransaction());
}
public void TestNoExistingSessionBeginsNewTransaction()
{
// Arrange
var session = MockRepository.GenerateMock<ISession>();
var tx = MockRepository.GenerateMock<ITransaction>();
var sut = new Sut(session);
sut.HasExistingSession = false;
session.Expect(x => x.BeginTransaction()).Return(tx);
// Act
sut.TransactionSave("foo");
// Assert
session.AssertWasCalled(x => x.Save("foo");
session.AssertWasCalled(x => x.BeginTransaction());
tx.AssertWasCalled(x => x.Commit());
}
