Rails rspec LoadError: cannot load such file — main_helper

Question

I have this code in my 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) }

I want to move it to helper. So I created main_helper.rb in helpers folder

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

In my authorization_spec.rb I wrote this:

require 'main_helper'

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

But got an error: LoadError: cannot load such file -- main_helper I removed required line and got this error: UPD: $load path:

Answer 1

spec/helpers is where RSpec rails places specs for rails helpers.

$ 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

Move the file to spec/support which is where any files which are used solely by the testing system should go.

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

RSpec adds the /spec dir to the load path. Which is why you can do require 'spec_helper' . To require a file from the support dir you would do require 'support/main_helper' .
