Rhinomock error Expected #1, Actual #0. Source=<Cannot evaluate the exception source>

[Jaison Peter]

I am a newbie to Rhino

I have method written like below :

    [TestMethod]

        public void WhenProducitonOrderList_IsNotFromPaperlessWarehouse_POList_IsNotSent()

        {

            // arrange

            MockProductionOrders.ProductCodeInfoList = new string[]

            {

                "5150-000002,INPA160336611,5150-000020,C,30,FR,,,,,,,,INPA,5150",

                "5150-000001,INGA1390368811,5150-000001,C,30,FR,,,,,,,,INGA,5150"

            };

            var purchPRDListMock = MockProductionOrders.CreateTestProductionOrders();

            var purchPRDListRepositoryMock = MockRepository.GenerateMock<IProductionOrderRepository>();

            purchPRDListRepositoryMock.Expect(x => x.GetNewProductionOrders(Arg<DateTime>.Is.Anything)).Return(purchPRDListMock);

            var purchPRDListEnueratedMock = MockProductionOrders.CreateTestProductionOrder();

            var productionOrderManagerMock = MockRepository.GenerateMock<IProductionOrderManager>();

            productionOrderManagerMock.Expect(x => x.SendToWms(Arg<IEnumerable<ProductionOrderToWMS>>.Is.Anything)).Return(purchPRDListEnueratedMock);

            var purchPRDValidator = new ProductionOrderValidator();

            var purchaseOrderToWmsServiceMock = MockRepository.GenerateMock<PurchaseOrderToWMSPort>();

            var soapAdapterMock = MockRepository.GenerateMock<ISoapAdapter<PurchaseOrderToWMSPort>>();

            soapAdapterMock.Expect(x => x.GetService()).Return(purchaseOrderToWmsServiceMock);

            var purchPRDRequestMock = MockRepository.GenerateMock<PurchaseOrderToWMSOperationRequest>();

            var axToWmsPRDManager = new AxToWmsProdManager(purchPRDListRepositoryMock, purchPRDValidator, productionOrderManagerMock, MockRepository.GenerateMock<IAuditor>());          

            

            // act

            axToWmsPRDManager.Execute();

            //assert           

            //purchPRDListRepositoryMock.VerifyAllExpectations();

            //productionOrderManagerMock.VerifyAllExpectations();

            //purchaseOrderToWmsServiceMock.VerifyAllExpectations();            

            purchaseOrderToWmsServiceMock.AssertWasCalled(x => x.PurchaseOrderToWMSOperation(purchPRDRequestMock));

        }

the line below throws error :

>  purchaseOrderToWmsServiceMock.AssertWasCalled(x =>

> x.PurchaseOrderToWMSOperation(purchPRDRequestMock));

This is error:

> Rhino.Mocks.Exceptions.ExpectationViolationException occurred

Could you help me what is going wrong?

**Updates**

> I changed the line as below, still i am getting same error

`purchaseOrderToWmsServiceMock.AssertWasCalled(x => x.PurchaseOrderToWMSOperation(Arg<PurchaseOrderToWMSOperationRequest>.Is.Anything));` –

> when i changed the line to below it is NOT throwing any errors

 `purchaseOrderToWmsServiceMock.AssertWasNotCalled(x => x.PurchaseOrderToWMSOperation(Arg<PurchaseOrderToWMSOperationRequest>.Is.Anything));`
