Why is my NUnit test failing?

Question

I added an NUNit test (NUnit newby here):

[Test]
public void TestHHSDeliveryInterface()
{
    var Delivery = IOC.container.Resolve<IHHSDelivery>();

    var i = Delivery.GetCount();

    Assert.Greater(i, 16);
}

...based on an existing one that works:

[Test]
public void TestHHSInterface()
{
    var HHSClient = IOC.container.Resolve<IHHSClient>();

    var s = HHSClient.GetTestMessage("Dom", "Paz");

    Assert.Greater(s.Value.Length, 0);
}

...for some context, the class starts this way:

[TestFixture, Category(SSCSCOMMON.UnitTests.Categories.IntegrationTest)]
public class HHSClientIntegrationTests
{

The method (Delivery.GetCount();) is returning a "canned" value (17) for now. So it itself works. So why is the test failing? Unfortunately, the test code is not breakpointable - at least, I have a breakpoint in it, and it doesn't ever get reached, which it should if it's failing, I would think, normally. NUnit looks like this after I run the app and the tests:

With the problematic test commented out, the others run fine.

UPDATE

It turns out that solving this problem also solved this one.

It's hard to tell without the code lines in your example. But the error message is saying that the failure is on line 59 of `RESTHHSDelivery.cs` Are you sure you are getting back the correct `IHHSDelivery` instance from `IOC.container.Resolve()` in your test? — Caleb, Jun 24 '14 at 00:06
Can you show the `RESTHHSDelivery.cs` code? It would seem that something in there is throwing a `System.NotImplementedException`. This is often the case when you create classes and methods using IDE tools. Check your constructors, and the implementation for `GetCount()` — Caleb, Jun 24 '14 at 00:10

Using my psychic debug skills:

You are not running the unit test on the dll you think you are debugging. I guess your debug breakpoint tells you the code you are running differs form the source code. Clean your deployment directories/ and your project (all dlls) and recompile.
