    VS 2010, 4.0....C# and NUnit
    Hoping someone can help me out. I am trying to store and retrieve items from an interface and create Nunit tests on them and am lost. I believe the impl and interface are correct but I am having problems figuring out how to write the tests to test that the item was stored, retrieved and then compare the two to see if they are the same.
    Code:
    using System;
    using System.IO;
    using System.Collections;
    using System.Collections.Generic;
    using System.Linq;
    using System.Text;
    
    namespace ReneApp.Domain
    {
        using ReneApp.Service;
    
        using NUnit.Framework;
        [TestFixture]
    
        public class ItemSvcIntTest 
        {
            [Test]
            public void ValidateStoreItem()
            {
                IitemSvcInt serv1 = new ItemSvcBinaryImpl();
                serv1.StoreItem(new Item("Stock", "Dark Rival", "Masters of Time", "Brenda Joyce", "Book", "Time Travel", true));
                [URL=http://www.go4expert.com/articles/c-cpp-assert-function-t27488/]Assert[/URL].AreEqual(serv1, serv1); 
            }
    
            public void ValidateRetrieveItem()
            {
    
            }
        }
    } using System;
    using System.Collections.Generic;
    using System.Linq;

    {
        public class TransFactory
        {
            public IitemSvcInt GetItemSvc()
            {
                return new ItemSvcBinaryImpl();
            }
        }
    } using System;

                    return false;
                if (title == null)
                    return false;
                return true;
            } 
        }
    
        // Declare type to process item.
        public delegate void ProcessItemDelegate(Item item);
    }
    
    Any assistance would be greatly appreciated :)
