Rails: add a route for a test

To test a feature flag implementation, we create a one-off controller in the test and check the response codes for getting its #index. We don't want the route for this controller in our actual routes.rb, so I wrapped it in a before block of our test:

describe FeatureTestController, :type => :controller do
 before do
 Rails.application.routes.draw do
 match '/feature_test' => 'feature_test#index'
 end
 end
 after do
 Rails.application.reload_routes!
 end
 describe '#index' do
 # ...
 end
end

#ruby

describe ApplicationTestController do
 routes ApplicationTestController
 ... tests ...
end



def self.routes(controller)
 before do
 controller_name = controller.to_s.underscore.chomp('_controller')
 Rails.application.routes.draw do
 match "test/:action", controller: controller_name, via: [:get, :post, :patch, :delete]
 end
 end

 after do
 Rails.application.reload_routes!
 end
 end

it should Rails.application.routes.append instead of Rails.application.routes.draw, because #draw resets all existing routes
