copied!<p>You would need to override <code>.Equals()</code> so that it compared <code>properties</code>, then use the</p> <p><code>Assert.AreEqual Method (Object, Object)</code>. Please see below:</p> <p><a href="https://stackoverflow.com/questions/318210/compare-equality-between-two-objects-in-nunit">Compare equality between two objects in NUnit</a></p> <p>You would want to implement such a thing in your model itself.</p> <pre><code>// useful class public class MyStuff { public int Id { get; set; } public string Name { get; set; } public int MyValue { get; set; } public override int GetHashCode() { return Id; } public override bool Equals(object obj) { if (ReferenceEquals(this, obj)) return true; if (obj.GetType() != typeof (MyStuff)) return false; var other = obj as MyStuff; return (other.Id == Id && other.MyValue == MyValue && other.Equals(other.Name, Name)); // use .Equals() here to compare objects; == for Value types // alternative weak Equals() for value objects: // return (other.MyValue == MyValue && other.Equals(other.Name, Name) ); } } </code></pre> <p><strong>EDIT:</strong> In retrospect, I have decided that having a duplication of properties in your viewmodel and model is probably a bad pattern and is part of the reason you are having so many testing issues. Rather, you should allow your ViewModel to wrap your model.</p> <pre><code>public class CustomerViewModel { // This is the same as CustomerModel.CustomerName, but the names differ public CustomerModel CustomerModel { get; set; } pubiic CustomerViewModel() { CustomerModel = new CustomerModel(); } } public class CustomerModel { public string CustomerName { get; set; } public int ID { get; set; } } </code></pre> <p>At that point it's much easier to test it since you have your wrapped model that you can compare to a new copy of the same model, using the .Equals override pattern. At the end of the day I just don't think that trying to come up with a magic bullet "compare any model to any model" is a good idea, nor is it practical.</p>
