Rails rspec LoadError: cannot load such file -- main_helper
<p>I have this code in my <code>spec/features/authorization_spec.rb</code></p>

<pre><code>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) }
</code></pre>

<p>I want to move it to helper.
So I created main_helper.rb in helpers folder</p>

<pre><code>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
</code></pre>

<p>In my authorization_spec.rb
I wrote this:</p>

<pre><code>require 'main_helper'

RSpec.describe "Authorization", type: :request do
MainHelper.auth
</code></pre>

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

<pre><code>irb(main):003:0&gt; $LOAD_PATH
