Question

Assuming an IMouvement Object which contains some subobjects like ITache, IStockPalette.

public interface IMouvement : IObjectBase<Guid> {         ITache Tache { get; set; }         IStockPalette StockPalOrigine { get; set; } } 

How can I Mock this using Rhino Mocks ?

Assuming this test, what’s wrong with this ?

[TestMethod] public void Can_Validate_EmplacementTransitoireRule() {     var mocks = new MockRepository();     var mouvement = mocks.StrictMock<IMouvement>();     var manager = mocks.StrictMock<ValidationManager>();      mouvement.Tache = mocks.StrictMock<ITache>();     mouvement.StockPalOrigine = mocks.StrictMock<IStockPalette>();     mouvement.ID = Guid.NewGuid();      var rule = new EmplacementTransitoireRule(mouvement);     manager.AddRule(rule);      Expect.Call(manager.ValidateAll()).Return(true);      mocks.ReplayAll();      var all = manager.ValidateAll();      mocks.VerifyAll();      Assert.IsTrue(all); } 

this Test always fails ..

Typically I would set up expectations on the mock objects instead of merely assigning their properties.

 Tache tache = mocks.StrictMock<Tache>();  Expect.Call( mouvement.Tache ).Return( tache ); 

Also, you may want to use the AAA (Arrange-Act-Assert) syntax for RhinoMocks — I believe that StrictMock has been deprecated.

 Mouvement mouvement = MockRepository.GenerateMock<Mouvement>();  Tache tache = MockRepository.GenerateMock<Tache>();   mouvement.Expect( m => m.Tache ).Return( tache );  tache.Expect( t => t.Value ).Return( 100 );  // or whatever   ... test code...   tache.VerifyAllExpectations();  mouvement.VerifyAllExpectations();
