The other day I was spec’ing out some new routes for my application and I wanted to make sure certain routes were ignored. Not happy with the disgustingly-verbose way of testing routes OOTB with asp.net MVC, I decided to lean on the great work Ben Schierman did in his fluent route testing extensions.

I whipped together a quick extension method that allows me to do the following:

   1:  public class when_requesting_a_gif_file : with_routes_configured

   2:  {

   3:      [Test]

   4:      public void should_ignore_the_route()

   5:      {

   6:          "~/my_file.gif".ShouldBeIgnored();

   7:      }

   8:  }

Building the extension was a snap – I leveraged the work already in place for the other fluent route testing extensions, and just made sure the RouteHandler responsible for the given route pattern was a StopRoutingHandler. It looks something like this:

   1:  public static class RouteTestingExtensions

   2:  {

   3:      public static RouteData ShouldBeIgnored(this string relativeUrl)

   4:      {

   5:          RouteData routeData = relativeUrl.Route();

   6:          routeData.RouteHandler.ShouldBeOfType<StopRoutingHandler>();

   7:   

   8:          return routeData;

   9:      }

  10:  }

And that's all there is to it!

I’ll be submitting I have submitted this as a patch to MVC Contrib project within the next few minutes. Hopefully I can coax one of the committers into applying it. But until then, just steal my code and roll it into your code base!
