You can't act on your SUT before you setup your expectations.
[TestFixture]
public class ATest
{
private IActor actor;
private List<int> list1, list2;
private Manager manager;
[SetUp]
public void BeforeEachTest()
{
list1 = new List<int>();
list2 = new List<int>();
actor = MockRepository.GenerateMock<IActor>();
manager = new Manager(actor);
}
[Test]
public void should_perform_on_one()
{
actor.Expect(a => a.PerformAction(list1));
manager.DoItOnActor(list1);
manager.DoItOnActor(list2);
actor.VerifyAllExpectations();
}
[Test]
public void should_perform_on_two()
{
actor.Expect(a => a.PerformAction(list2));
manager.DoItOnActor(list1);
manager.DoItOnActor(list2);
actor.VerifyAllExpectations();
}
}
