Testing environment dependent routing with RSPEC

Question

I have some routes that should only exist in the development environment but I can't get the specs for this working. Any ideas what I am doing wrong? I initially tried this in the controller spec but then realised I need :type => :routing to use be_routable so have separated this out. I have debugged and Rails.env has the values I expect in each context. Do I need to reload the routes? Have tried to do this but can't find a syntax that rspec is happy with...

Snippet from routes.rb:

    resources :users do
        collection do
          ...
          if Rails.env.development?
            get :new_development_account
            post :create_development_account
          end
        end
        ...

Routing spec:

require 'spec_helper'

describe "routes for users controller", :type => :routing do

    context "production environment" do
      it "development routes do not exist" do
        allow(Rails).to receive(:env) { "production".inquiry }
        expect(:get => "/ims/users/new_development_account").not_to be_routable
        expect(:post => "/ims/users/create_development_account").not_to be_routable
      end
    end

    context "development environment" do
      it "development routes exist" do
        allow(Rails).to receive(:env) { "development".inquiry }
        expect(:get => "/ims/users/new_development_account").to be_routable
        expect(:post => "/ims/users/create_development_account").to be_routable
      end
    end
end

What is particularly odd is that it fails both tests:

Failures:

  1) routes for users controller production environment development routes do not exist
     Failure/Error: expect(:get => "/ims/users/new_development_account").not_to be_routable
       expected {:get=>"/ims/users/new_development_account"} not to be routable, but it routes to {:action=>"show", :controller=>"ims/users", :id=>"new_development_account"}

  2) routes for users controller development environment development routes exist

       expected {:post=>"/ims/users/create_development_account"} to be routable

Answer 1

The routes can be reloaded with Rails.application.reload_routes!.

Example:

it "does not have routes in production" do
  allow(Rails).to receive(:env) { "production".inquiry }
  Rails.application.reload_routes!
  expect(:get => "/ims/users/new_development_account").not_to be_routable
  expect(:post => "/ims/users/create_development_account").not_to be_routable
end
