Rails RSpec LoadError: не может загрузить такой файл - main_helper

Question

У меня есть этот код в моем spec/features/authorization_spec.rb

let!(:user) { FactoryGirl.create(:user) } 
let!(:q) { FactoryGirl.create(:question, user: user, body: "sample text", title: "sample title") } 
let!(:answer) { FactoryGirl.create(:answer, user: user, question: q) } 

Я хочу, чтобы переместить его помощника. Так что я создал main_helper.rb в папке хелперов

RSpec.describe MainHelper, type: :helper do 
    def auth 
     let!(:user) { FactoryGirl.create(:user) } 
     let!(:q) { FactoryGirl.create(:question, user: user, body: "sample text", title: "sample title") } 
     let!(:answer) { FactoryGirl.create(:answer, user: user, question: q) } 
    end 
end 

В моем authorization_spec.rb я написал это:

require 'main_helper' 

RSpec.describe "Authorization", type: :request do 
MainHelper.auth 

Но получил ошибку: LoadError: cannot load such file -- main_helper я удалил нужную строку и получил эту ошибку : UPD: $ путь загрузки:

Answer 1

spec/helpers где RSpec рельсы размещают спецификации для помощников рельсов.

$ rails generate helper foo 
Running via Spring preloader in process 19017 
     create app/helpers/foo_helper.rb 
     invoke rspec 
     create spec/helpers/foo_helper_spec.rb 

Переместить файл в spec/support который где-либо файлы, которые используются исключительно в системе тестирования должен идти.

$ mv spec/helpers/main_helper.rb spec/support/main_helper.rb 

RSpec добавляет /spec каталог в пути загрузки. Вот почему вы можете сделать require 'spec_helper'. Чтобы потребовать файл из каталога поддержки, вы сделаете require 'support/main_helper'.
