I have simplified an issue I am having to the following
I have a route that looks like this
namespace :client do
resources :thing, :only => [:index]
end
and the simple rspec test
describe Client::ThingController do
describe "GET 'index'" do
it "returns http success" do
get 'index'
response.should be_success
end
end
end
However what I'd like to do is alter the url I use to access the resource from
/client/thing.json
to
/api/client/v1/thing.json
1) How do I update my routes and rspec?
If I then wanted to parameterise the uri such that I could extract the api_version
/api/client/[api_version]/thing.json
2) How would this effect my routes and simple rspec test?
I'd previously tried what #Mori had suggested before I had posted but without having the multiple routes as proposed, I should have mentioned that in the original post.
What I eventually got that worked is:
1) In routes.rb I added
match "api/client/:api_version/thing" => 'client/thing#index'
NOTE: The missing leading '/' ie match "/api/... => match "api/... it seems to make all the difference to rspec.
2) And in my rspec thing_controller_spec.rb I now have this
describe Client::ThingController do
describe "GET 'index'" do
it "returns http success" do
get 'index', :api_version => 'v1'
response.should be_success
end
end
end
I was close before but it was the leading '/' in routes.rb that broke me even though I could navigate to the url in a browser.

I'm trying to write a controller test and Rspec isn't finding routes that I know exist and work fine on a development server.
In my routes I have a catch-all route that should redeirect to a generic controller if someone goes to a route that isn't predefined.
routes.rb
namespace :tools do
match '*unmatchedpath' => "generic#show", :via => :get
end
generic_controller.rb
def show
# do stuff
end
generic_controller_spec.rb
require 'spec_helper'
describe Tools::GenericController do
describe 'GET show' do
it 'does stuff' do
get :show
end
end
Here is the error I get from rspec when I run the test above
1) Tools::GenericController GET show does stuff
Failure/Error: get :show
ActionController::RoutingError:
No route matches {:controller=>"tools/generic", :action=>"show"}
All routes work as expected on my development server so I'm not sure why Rspec isn't finding the route.
Try:
get '*unmatchedpath' => 'tools/generic#show'
This question has probably been asked a dozen times on Stack Overflow (e.g. (1), (2), (3), (4), (5)) but every time the answer seems to be different and none of them have helped me. I'm working on a Rails Engine and I'm finding that Rspec2 gets route errors, but I can reach the routes in the browser. Here's the situation:
In the engine's routes.rb:
resources :mw_interactives, :controller => 'mw_interactives', :constraints => { :id => /\d+/ }, :except => :show
# This is so we can build the InteractiveItem at the same time as the Interactive
resources :pages, :controller => 'interactive_pages', :constraints => { :id => /\d+/ }, :only => [:show] do
resources :mw_interactives, :controller => 'mw_interactives', :constraints => { :id => /\d+/ }, :except => :show
end
Excerpted output of rake routes:
new_mw_interactive GET /mw_interactives/new(.:format) lightweight/mw_interactives#new {:id=>/\d+/}
...
new_page_mw_interactive GET /pages/:page_id/mw_interactives/new(.:format) lightweight/mw_interactives#new {:id=>/\d+/, :page_id=>/\d+/}
And my test, from one of the controller specs (describe Lightweight::MwInteractivesController do):
it 'shows a form for a new interactive' do
get :new
end
...which gets this result:
Failure/Error: get :new
ActionController::RoutingError:
No route matches {:controller=>"lightweight/mw_interactives", :action=>"new"}
...and yet when I go to that route in the browser, it works exactly as intended.
What am I missing here?
ETA: To clarify a point Andreas raises: this is a Rails Engine, so rspec runs in a dummy application which includes the engine's routes in a namespace:
mount Lightweight::Engine => "/lightweight"
...so the routes shown in rake routes are prefaced with /lightweight/. That's why the route shown in the Rspec error doesn't seem to match what's in rake routes. But it does make the debugging an extra step wonkier.
ETA2: Answering Ryan Clark's comment, this is the action I'm testing:
module Lightweight
class MwInteractivesController < ApplicationController
def new
create
end
...and that's it.
I found a workaround for this. Right at the top of the spec, I added this code:
render_views
before do
# work around bug in routing testing
#routes = Lightweight::Engine.routes
end
...and now the spec runs without the routing error. But I don't know why this works, so if someone can post an answer which explains it, I'll accept that.
I think the might be something wrong higher up in you specs
how did the "lightweight" get into this line :controller=>"lightweight/mw_interactives"
the route says
new_mw_interactive GET /mw_interactives/new(.:format)
not
new_mw_interactive GET /lightweight/mw_interactives/new(.:format)
add a file spec/routing/root_routing_spec.rb
require "spec_helper"
describe "routes for Widgets" do
it "routes /widgets to the widgets controller" do
{ :get => "/" }.should route_to(:controller => "home", :action => "index")
end
end
then add a file spec/controllers/home_controller_spec.rb
require 'spec_helper'
describe HomeController do
context "GET index" do
before(:each) do
get :index
end
it {should respond_with :success }
it {should render_template(:index) }
end
end
I create all the routes of my program manually and so do with my rspec tests of course. Generally, my routes and tests work fine, but i have a problem with the test for my characters controller. The route is :
scope :path => '/characters', :controller => :characters do
get '/' => :show, :as => 'user_character'
end
The /characters works fine when tested with my browser. Everything seems fine. But, the test :
require 'spec_helper'
require 'devise/test_helpers'
describe CharactersController do
login_user
describe "when it GETS 'show'" do
it "should render the template and be successful" do
get :show
response.should render_template(:show)
response.should be_success
end
end
end
Fails with the error :
1) CharactersController when it GETS 'show' should render the template and be successful
Failure/Error: get :show
ActionController::RoutingError:
No route matches {:controller=>"characters", :action=>"show"}
# ./spec/controllers/characters_controller_spec.rb:9
All my controllers have similar tests that work fine. Why does this not work ?
IMPORTANT EDIT :
Just saw that if i turn Spork off, the test passes ! Why is this happening ? Does Spork need to be restarted every time a new test is added ?
You have to restart spork when changing routes.
Or put this in your spec_helper.rb:
Spork.each_run do
ApplicationName::Application.reload_routes!
end

I;m trying to write a spec that tests a controller that is namespaced, let's call it Admin::FooController. My spec is called admin_foo_controller_spec.rb. In the spec, I'm trying to write a very basic spec to see if it can retrieve an action of a controller.
describe "GET 'index'" do
it "should be successful" do
get 'index'
response.should be_success
end
end
But instead I get an error:
Failure/Error: get 'index'
No route matches {:controller=>"admin/foo"}
For another action, I have basically the same test, and I get that the response is not successful. In the actual webapp, I can access these urls fine. One thing I should mention is that this isn't a RESTful resource (it makes no sense as one) so it's really just a group of related administrative actions, so in my routes.rb it's basically like
namespace :admin do
scope "foo" do
match "action1" => "foo#action1"
match "action2" => "foo#action2"
match "/index" => "foo#settings"
match "settings" => "foo#settings"
end
end
Any ideas what I'm doing wrong? It seems like namespacing is asking for trouble with rails, especially for a novice like me. Thanks!
In your route your have no index action in you Foo controller try to get 'settings'
describe "GET 'index'" do
it "should be successful" do
get 'settings'
response.should be_success
end
end
In a controller spec you need define the action of your controller not the real route. You try the routes in a integration test.
I've got a controller that can't be accessed directly, in the traditional RESTful way, but rather only through a particular url.
Normally I'm used to using get and post in my controller specs to call controller actions. Is there a way that I can exercise my controller by visiting a particular url?
EDIT:
Here is my route:
Larzworld::Application.routes.draw do
match '/auth/:provider/callback' => 'authentications#create'
devise_for :users, :controllers => {:registrations => "registrations"}
root :to => 'pages#home'
end
Here is my spec:
require 'spec_helper'
describe AuthenticationsController do
before(:each) do
request.env["omniauth.auth"] = {"provider" => "twitter", "uid" => "12345678"}
end
describe 'POST create' do
it "should find the Authentication using the uid and provider from omniauth" do
Authentication.should_receive(:find_by_provider_and_uid)
post 'auth/twitter/callback'
end
end
end
and here is the error I receive:
Failures:
1) AuthenticationsController POST create should find the Authentication using the uid and provider from omniauth
Failure/Error: post 'auth/twitter/callback'
No route matches {:action=>"auth/twitter/callback", :controller=>"authentications"}
# ./spec/controllers/authentications_controller_spec.rb:13
Finished in 0.04878 seconds
1 example, 1 failure
Controller tests use the four HTTP verbs (GET, POST, PUT, DELETE), regardless of whether your controller is RESTful. So if you have a non-RESTful route (Rails3):
match 'example' => 'story#example'
the these two tests:
require 'spec_helper'
describe StoryController do
describe "GET 'example'" do
it "should be successful" do
get :example
response.should be_success
end
end
describe "POST 'example'" do
it "should be successful" do
post :example
response.should be_success
end
end
end
will both pass, since the route accepts any verb.
EDIT
I think you're mixing up controller tests and route tests. In the controller test you want to check that the logic for the action works correctly. In the route test you check that the URL goes to the right controller/action, and that the params hash is generated correctly.
So to test your controller action, simply do:
post :create, :provider => "twitter"`
To test the route, use params_from (for Rspec 1) or route_to (for Rspec 2):
describe "routing" do
it "routes /auth/:provider/callback" do
{ :post => "/auth/twitter/callback" }.should route_to(
:controller => "authentications",
:action => "create",
:provider => "twitter")
end
end
