title: ActiveRecord::StatementInvalid: PG::ConnectionBad: PQsocket() can't get socket descriptor: BEGIN
body: <p>I'm new in watir and I'm trying to use watir to test my rails app. I have next code:</p>
  
  <pre><code>require 'watir_helper'
  require 'spec_helper'
  
  RSpec.feature 'Questions hub', type: :request do
    let!(:user) { create(:user, email: 'test1@example.com', name: 'John', last_name: 'Stivens') }
    let!(:question) { create(:question, created_at: 'August 25, 2016', user: user) }
  
    describe 'Comments feature' do
      context 'When user signed in' do
        def sign_in_user
          goto new_user_session_path
          text_field(name: 'user[email]').set('test1@example.com')
          text_field(name: 'user[password]').set('12345678')
          button(name: 'commit').click
        end
  
        def visit_question_page_and_post_answer
          goto question_path(question)
          textarea(id: 'answer_content').set('Lorem Ipsum')
          button(name: 'commit').click
        end
  
        def add_comment_to_answer
          link(text: 'comments (0)').click
          link(text: 'Add Comment').when_present.click
          textarea(name: 'comment[content]').set('MyComment')
          button(name: 'commit').click
        end
  
        before do
          sign_in_user
          visit_question_page_and_post_answer
        end
  
        it "Check comments count when it's empty" do
          text.include? 'comments (0)'
        end
  
        it "Add comment to question's answer" do
          add_comment_to_answer
  
          text.include? 'MyComment'
          text.include? 'comments (1)'
        end
  
        it 'Comment has link to user profile' do
          add_comment_to_answer
          div(class: 'user-name-w').link(text: 'John Stivens').click # problem happens here
        end
      end
    end
  end
  </code></pre>
  
  <p>And when I have next line in the code:</p>
  
  <pre><code>div(class: 'user-name-w').link(text: 'John Stivens').click
  </code></pre>
  
  <p>this test fails with error:</p>
  
  <pre><code>ActiveRecord::StatementInvalid: PG::ConnectionBad: PQsocket() can't get socket descriptor: BEGIN
  </code></pre>
  
  <p>But if to conmment 2 previous tests, the third test (where problem happens) will pass.</p>
