I have been waiting on the release for Rhino Mocks 3.5, seeing what kind of feedback I can get from users. I also had another reason, I hadn't had the chance to really give it a good testing, in the only manner that matter, using it to develop production ready software.

Here is my latest test, which I am fairly pleased with.

[TestFixture]
public class WebcastControllerTest
{ 
	private WebcastController controller;
	private IRepository<Webcast> repositoryStub;
	private StubEngineContext engineContext;
	private IUnitOfWork unitOfWorkStub;
	private IDisposable disposeGlobalUnitOfWorkRegistration;

	[SetUp]
	public void Setup()
	{
		repositoryStub = MockRepository.GenerateStub<IRepository<Webcast>>();
		unitOfWorkStub = MockRepository.GenerateStub<IUnitOfWork>();
		controller = new WebcastController(repositoryStub)
		             	{
		             		ControllerContext = new ControllerContext{Name = "webcast"},
		             	};
		engineContext = new StubEngineContext();
		controller.SetEngineContext(engineContext);
		disposeGlobalUnitOfWorkRegistration = UnitOfWork.RegisterGlobalUnitOfWork(unitOfWorkStub);
	}

	[TearDown]
	public void TearDown()
	{
		disposeGlobalUnitOfWorkRegistration.Dispose();
	}

	[Test]
	public void When_index_called_will_send_existing_webcasts_to_view()
	{
		var webcasts = new List<Webcast>();
		repositoryStub.Stub(x => x.FindAll()).Return(webcasts);

		controller.Index();

		Assert.AreSame(webcasts, controller.PropertyBag["webcasts"]);
	}

	[Test]
	public void When_display_called_will_send_webcast_to_view()
	{
		var webcast = new Webcast();
		controller.Display(webcast);

		Assert.AreSame(webcast, controller.PropertyBag["webcast"]);
	}

	[Test]
	public void When_edit_called_with_webcast_will_send_webcast_to_view()
	{
		var webcast = new Webcast();
		controller.Edit(webcast);

		Assert.AreSame(webcast, controller.PropertyBag["webcast"]);
	}

	[Test]
	public void When_saving_invalid_webcast_will_redirect_to_edit()
	{
		var webcast = new Webcast();

		controller.Validator.IsValid(webcast);
		controller.PopulateValidatorErrorSummary(webcast, controller.Validator.GetErrorSummary(webcast));

		controller.Save(webcast);

		Assert.Contains(engineContext.MockResponse.RedirectedTo, "edit");
	}

	[Test]
	public void When_saving_invalid_webcast_will_flash_error_summary_and_webcast_in_flash()
	{
		var webcast = new Webcast();

		controller.Validator.IsValid(webcast);
		controller.PopulateValidatorErrorSummary(webcast, controller.Validator.GetErrorSummary(webcast));

		controller.Save(webcast);

		Assert.AreSame(webcast, controller.Flash["webcast"]);
		Assert.AreSame(controller.Validator.GetErrorSummary(webcast), controller.Flash["errorSummary"]);
	}

	[Test]
	public void When_saving_valid_webcast_will_redirect_to_display()
	{
		var webcast = new Webcast();

		// explicitly not calling validation, the controller will assume 
		// that this is a valid object

		controller.Save(webcast);

		Assert.Contains(engineContext.MockResponse.RedirectedTo, "display");
	}

	[Test]
	public void When_saving_valid_webcast_will_save_and_flash_unit_of_work()
	{
		var webcast = new Webcast();

		// explicitly not calling validation, the controller will assume 
		// that this is a valid object

		controller.Save(webcast);

		repositoryStub.AssertWasCalled(x=>x.Save(webcast));
		unitOfWorkStub.AssertWasCalled(x=>x.TransactionalFlush());
	}
