Factories not loading with single test but loads with all tests - ruby-on-rails

Question

I am following the rails api book but building the code in an engine. The test is at spec/controllers/concerns/handicap/authenticable_spec.rb and looks like this
require 'spec_helper'
require_relative '../../../../app/controllers/concerns/handicap/authenticable.rb'
class Authentication
include Handicap::Authenticable
end
module Handicap
describe Authenticable, type: :controlller do
let(:authentication) { Authentication.new }
subject { authentication }
describe "#current_user" do
before do
#user = FactoryGirl.create :handicap_user
request.headers["Authorization"] = #user.auth_token
authentication.stub(:request).and_return(request)
end
it "returns the user from the authorization header" do
expect(authentication.current_user.auth_token).to eql #user.auth_token
end
end
end
end
When I run the test directly i.e. rspec ./spec/controllers/concerns/handicap/authenticable_spec.rb I get an error:
uninitialized constant Handicap::FactoryGirl
However, when I run all the tests i.e. rspec spec, it does find the FactoryGirl constant and the test fails with
undefined local variable or method `request' for #<RSpec::ExampleGroups::HandicapAuthenticable::CurrentUser:0x007ff276ad5988>.
According to this github issue, I need to add < ActionController::Base to the Authentication class i.e.
class Authentication < ActionController::Base
but if I add this in, I get
uninitialized constant ActionController
I have also tried adding < Handicap::ApplicationController but get
uninitialized constant Handicap::ApplicationController
There appears to be something wrong with my namespacing. There are three symptoms, the fact that FactoryGirl cannot be found if I run the test by itself, but is found when all the tests are run. The second is that it cannot find ActionController even when all the tests are run. The third is that I need to add the line:
require_relative '../../../../app/controllers/concerns/handicap/authenticable.rb'
to find the module that is being tested.
How do I fix my namespacing?
The rails_helper.rb file is
ENV['RAILS_ENV'] ||= 'test'
require File.expand_path('../dummy/config/environment.rb', __FILE__)
require 'rspec/rails'
require 'capybara'
require 'capybara/rails'
require 'capybara/rspec'
require 'capybara-screenshot'
require 'capybara-screenshot/rspec'
require 'capybara/poltergeist'
require 'capybara/email/rspec'
require 'pp'
require 'chris_api_helpers'
# Prevent database truncation if the environment is production
abort("The Rails environment is running in production mode!") if Rails.env.production?

and the spec_helper.rb is

Answer 1

You should not be putting specs into modules. This is the cause of problem here. If you need to reference a namespaced class, reference it like RSpec.describe Handicap::Authenticatable.
In general, when you are within a namespace and need to reference something explicitly from the 'root' scope, you can prepend it with double-colons. Such as:
module Handicap
class Something
def do_stuff
::FactoryGirl.create(:person)
end
end
end

Answer 2

It turns out that at the top of my file I should have had require 'rails_helper', not require 'spec_helper'``. All my other files hadrequire 'rails_helper'`` so when I ran the whole test suite, the rails_helper was being loaded anyway.
Embarrassing, but this Q&A might help someone else that has trouble spotting simple errors.
