Question

I’m trying to test that requesting the root path (/) routes to my beta controller’s :new action. When I do this manually (in my browser), it works fine. But my automated test is failing with No route matches "/".

In config/routes.rb I have

MyRailsApp::Application.routes.draw do
  root to: 'beta#new' # Previously: `redirect('/beta/join')`
end

In my spec/routing/root_route_spec.rb I have tried

require 'spec_helper'
describe "the root route" do
  it "should route to beta signups" do
    get('/').should route_to(controller: :beta, action: :new)
  end
end

and have also tried

require 'spec_helper'
describe "the root route" do
  it "should route to beta signups" do
    assert_routing({ method: :get, path: '/' }, { controller: :beta, action: :new })                                                                                                                                     
  end
end

but both complain that No route matches "/"

1) the root route should route to the beta signups
   Failure/Error: get('/').should route_to "beta#new"
     No route matches "/"
   # ./spec/routing/root_route_spec.rb:5:in `block (2 levels) in <top (required)>'

When I go, in my browser, to localhost:3000, I’m correctly routed to the BetaController::new action.

What explains the No route matches "/" error?

I’m using Rails 3.1.3 and RSpec-2.10.

Thanks!

You should test that / redirects to /beta/join and then as a separate issue test that /beta/join routes to the :new action of the :beta controller.

Redirection is tested in requests, not routing.

# spec/requests/foobar_spec.rb
describe 'root' do
  it "redirects to /beta/join" do
    get "/"
    response.should redirect_to("/beta/join");
  end
end

and

# spec/routing/beta_spec.rb
...
it 'routes /beta/join to the new action'
  get('beta/join').should route_to(:controller => 'beta', :action => 'new')
end
