A few observations: 1. The usage pattern for Unity seems a bit odd. I wouldn't expect to see any references to unity in the majority of an application's classes. One of the main points about IoC such as Unity is that it automatically resolves dependencies so if you changed your StatusBarModule constructor to take and IRegionManager and an IEventAggregator then when unity tries to build your StatusBarModule it will automatically populate those construction parameters. 2. Similarly with the call to Resolve<IStatusBarViewPresenter> this could/should be replaced with a dependency that is populated by unity (probably in the constructor). 3. Once you replace the constructor parameters your test can get rid of the MockUnityContainer and just create MockRegionManager (and other dependencies), pass it in explicitly in the constructor (Note that during the test Unity will not be used at all) Then in the actual test you can just write regionManager.AssertWasCalled(x=>x.RegisterViewWithRegion(....)
I must admit my knowledge of Prism and Unity is patchy, but with CAB (the precursor to Prism) this was how we worked. Try only having one place in your application aware of Unity, and let all the dependencies of your object graph be populated by unity. This will leave your application much less tightly bound to Unity. 2009/9/9 bill richards <[email protected]>: > > Alex, > > thanks for that, and the point is conceeded: > > The code as posted represents the "Arrange" aspect of the AAA test, > and the remainder was not posted, because at the time of posting, it > seemed superfluous to the issue I am trying to resolve. > > I also agree that there are quite a number of items being stubbed, but > this is due to the complexity of the framework (Prism V2). > > This is class definition for the object under test: > > public class StatusBarModule > { > public StatusBarModule(IUnityContainer container) > { > Container = container; > RegionManager = Container.Resolve<IRegionManager>(); > TheEventAggregator = Container.Resolve<IEventAggregator> > (); > } > > public IUnityContainer Container { get; private set; } > public IRegionManager RegionManager { get; private set; } > protected IEventAggregator TheEventAggregator { get; private > set; } > > public void > RegisterViewsAndServicesNotLoadedThroughConfiguration() { } > > public void RaiseAnyPertinentEventsEtc() { } > > public string ConfigurationContainerName { get { return > "Status"; } } > > public void Initialize() > { > var section = (UnityConfigurationSection) > ConfigurationManager.GetSection("Unity"); > if (section != null && section.Containers > [ConfigurationContainerName] != null) > section.Containers > [ConfigurationContainerName].Configure(Container); > > RegisterViewsAndServicesNotLoadedThroughConfiguration(); > RegisterViewsWithRegions(); > RaiseAnyPertinentEventsEtc(); > } > > public void RegisterViewsWithRegions() > { > RegionManager.RegisterViewWithRegion > (RegionNames.StatusBarRegion, () => > Container.Resolve<IStatusBarViewPresenter>().View); > } > > } > > And this is the full test: > > [Test] > public void > WhenInstantiated_ShouldRegisterIStatusBarViewWithRegionManager() > { > var unity = MockRepository.GenerateStub<IUnityContainer> > (); > var presenter = > MockRepository.GenerateStub<IStatusBarViewPresenter>(); > var view = MockRepository.GenerateStub<IStatusBarView>(); > presenter.View = view; > > var eventAggregator = > MockRepository.GenerateStub<IEventAggregator>(); > var regionManager = > MockRepository.GenerateStub<IRegionManager>(); > var region = MockRepository.GenerateStub<IRegion>(); > var regionCollection = > MockRepository.GenerateMock<IRegionCollection>(); > regionCollection.Add(RegionNames.StatusBarRegion, region); > > regionManager.Stub(r => r.Regions).Return > (regionCollection); > > unity.Stub(container => container.Resolve<IEventAggregator> > ()).Return(eventAggregator); > unity.Stub(container => container.Resolve<IRegionManager> > ()).Return(regionManager); > unity.Stub(container => > container.Resolve<IStatusBarViewPresenter>()).Return(presenter); > > new StatusBarModule(unity).Initialize(); // > RegionManager.Regions doesn't contain any regions!! > > unity.AssertWasCalled(container => > container.Resolve<IEventAggregator>()); > unity.AssertWasCalled(container => > container.Resolve<IRegionManager>()); > unity.AssertWasCalled(container => > container.Resolve<IStatusBarViewPresenter>()); > regionManager.AssertWasCalled(manager => > manager.RegisterViewWithRegion(RegionNames.StatusBarRegion, () => > presenter.View)); > } > > As you can see, the actual line fo code that I am testing is > > RegionManager.RegisterViewWithRegion > (RegionNames.StatusBarRegion, () => > Container.Resolve<IStatusBarViewPresenter>().View); > > Though now having described the whole scenario, I'm thinking that > really, what I am testing is whether or not the > "RegisterViewsWithRegions()" member is called; however without > stubbing the other required operands I cannot see how I would go about > defining that test. > > > > --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Rhino.Mocks" group.
