title: Unit Testing UrlHelper Extension Methods
body: <p>I'm trying to create unit tests to make sure my extension methods for UrlHelper work?  Does anyone know how to do this?  I'm using MVC 1.0 and MvcContrib.  I can test the routes but can't test code like this:</p>
  
  <pre><code>    public static string MoreFloorplans(this UrlHelper urlHelper, long productID, int pageIndex)
      {
       return urlHelper.Action&lt;CatalogController&gt;(x =&gt; x.GetRelatedProducts(productID, pageIndex));
  
      }
  </code></pre>
