Ruby on Rails3でRSpecを使ったルーティングのテストのコード

routes.rb

RspecRailsSample::Application.routes.draw do

  get "/" => "index#index", as: :index

  get "/user/:id(/max_id/:max_id)" => "index#user", as: :user

  post "/find" => "index#find", as: :find

end

routes_spec.rb

require 'spec_helper'

describe :routes do

  describe 'GET "index"' do
    subject { {get: '/'} }
    it { should route_to(controller: 'index', action: 'index') }
  end

  describe 'GET "user/1"' do
    context 'without max id' do
      subject { {get: '/user/1'} }
      it { should route_to(controller: 'index', action: 'user', id: '1') }
    end
