Feature: Engine routes for controllers
Controller specs can specify the routeset that will be used for the example
group. This is most useful when testing Rails engines.
Scenario: Specify engine routes
Given a file named "spec/controllers/widgets_controller_spec.rb" with:
"""ruby
require "rails_helper"
# A very simple Rails engine
module MyEngine
class Engine < ::Rails::Engine
isolate_namespace MyEngine
end
Engine.routes.draw do
resources :widgets, :only => [:show] do
get :random, :on => :collection
end
end
class WidgetsController < ::ActionController::Base
def random
@random_widget = Widget.all.shuffle.first
redirect_to widget_path(@random_widget)
end
def show
@widget = Widget.find(params[:id])
render :text => @widget.name
end
end
end
RSpec.describe MyEngine::WidgetsController, type: :controller do
routes { MyEngine::Engine.routes }
it "redirects to a random widget" do
widget1 = Widget.create!(:name => "Widget 1")
widget2 = Widget.create!(:name => "Widget 2")
get :random
expect(response).to be_redirect
expect(response).to redirect_to(assigns(:random_widget))
end
end
"""
When I run `rspec spec`
Then the examples should all pass
