System Test with Headless Chrome fails when entire test suite is run

[Jack Royal-Gordon]

I’ve got a system test that runs with headless Chrome (it’s the only system test I’ve written so far) that runs fine on it’s own, but when run as part of the entire test suite gives the following error:

Failure/Error: check 'send_amazon_email_after_processing'   # turns it on
     
     Capybara::ElementNotFound:
       Unable to find checkbox "send_amazon_email_after_processing"
     
     [Screenshot]: tmp/screenshots/failures_r_spec_example_groups_upload_features_amazon_toggle_send_email_flag_turns_off_the_flag_723.png

Here is the test:

require 'spec_helper'

require 'wait_for_ajax'

describe "Upload Features", js: true do

  describe 'Amazon' do

    describe 'Toggle "Send Email" flag' do

      before do

        @user = FactoryBot.create :user

        FactoryBot.create :user_distributor, :amazon, user: @user

        integration_sign_in(@user)

        visit uploads_path

        expect(page.title).to include 'Upload'

        wait_for_page_load

      end

      

      it 'defaults to off' do

        expect(page).to have_unchecked_field 'send_amazon_email_after_processing'

      end

      

    end

  end

end

The code in “wait_for_ajax”, which includes “wiat_for_page_load”, is:

module WaitForAjax

  def wait_for_ajax

    Timeout.timeout(Capybara.default_max_wait_time) do

      loop until finished_all_ajax_requests?

    end

  end

  def finished_all_ajax_requests?

    page.evaluate_script('jQuery.active').zero?

  end

  

  def wait_for_page_load(css='div#body')

    expect(page).to have_css(css)

  end

end

RSpec.configure do |config|

  config.include WaitForAjax, type: :system

end

The “wait_for_page_load” uses the method described here (https://stackoverflow.com/questions/42891801/netreadtimeout-netreadtimeout-and-seleniumwebdrivererrorunknownerror) for waiting for the page to load. And it works fine when I run the file by itself (e.g. “rspec ./spec/system/uploads_system_spec.rb”, but not when the entire suite is run “rspec”). When I look at the screen shot, I see a blank page with only the page header, but no other content. This is exactly what I saw when running the test standalone until I added the call to #wait_for_page_load.
