user_routing_spec.rb

# spec/routing/user_routing_spec.rb

require "spec_helper"

describe "routes for Users" do

  # passes!
  it "routes / to home" do
    get("/").should route_to("pages#home")
  end

  # passes!
  it "routes /:username to the users controller" do
    get("/vader").should be_routable
  end

  it "routes /:username to the users controller" do
    get("/vader").should route_to("users#show") # fails w/"Expected block to return value."
    get("/vader").should route_to("users#show", :username => 'vader') # passes!
  end

  it "named route" do
    # fails w/'No route matches {:controller=>"users", :action=>"show"}'
    { :get => user_profile_path }.should route_to(:controller => "users", :action => "show")

    { :get => user_profile_path("vader") }.should 
      route_to("users#show", :username => 'vader') # passes!
  end

end

The example on line 23 is telling you exactly why it's failing: there is no user_profile method, it's user_profile_path.

I think the one on line 18 should be:

get("/vader").should route_to("users#show", :username => "vader")

Not sure why the failure message is what it is, but let's see if this ^^ works first.

@dchelimsky you are correct, line 18 needed the :username => "vader". And yes, it would be nice if the error message were a bit more precise.

re: user_profile_path - gah, of course! actually calling the correct path helper is a good idea :) mea culpa!

however, it then fails because No route matches {:controller=>"users", :action=>"show"}

Thanks @aaronjensen and @joefiorini for pointing out that user_profile_path requires a parameter (the :username).

Clearly I'm too tired to be coding right now.
