Writing Tests for Rack Middleware Discussion

Great video Chris. 

Fantastic job on this video.  It was a great overview of a slightly more complex use of testing which I always appreciate.

Chris, nice video! 
But one thing is missing here, on the large app with a lot of tests passing script_name to the paths is cumbersome, helper need to be extracted that enables you to write 

visit posts_url

instead of

visit posts_url(script_name...)
