我正在使用：ruby 2.1.4、rails 4.1.12、rspec (2.14.1)和capybara (2.4.1)编写功能测试poltergeist (1.5.1)。

目前我有这样的功能：

require 'spec_helper'

feature 'user is able to import videos from YouTube Channel', js: true do

  before do
    @user = FactoryGirl.create :user
  end

  scenario 'from a simple correct YouTube video link' do
    VCR.use_cassette('video_sources/youtube_add_single_video') do

      visit root_path

      fill_in 'user_email',    with: @user.email
      fill_in 'user_password', with: @user.password
      click_button 'Log in'

      visit youtube_import_path

      expect(page).to have_css("input#query")
      expect(page).to have_css("a#continue-button")

      fill_in "query", with: "https://www.youtube.com/watch?v=xZY43QSx3Fk"

      page.find('#continue-button').trigger('click')

      # clicking on '#continue-button' call youtube API
      # receive a video data and store it into DB

      expect(page).to have_content("Congrats! Your import is complete")
    end
  end

end

本地一切正常，所有测试都是绿色的。但在 CodeShip 上 - 这种情况总是失败。而且我找不到原因...

CodeShip 日志说：

Capybara::Poltergeist::StatusFailError:
Request to 'http://127.0.0.1:3000/' failed to reach server, check DNS and/or server status

但为什么？本地所有测试都是绿色的。

PS我尝试sleep 5在行前添加visit root_path，但没有帮助。

PSS 也许这部分会spec_helper.rb有所帮助：

  config.before(:suite) do
    DatabaseCleaner.clean_with(:truncation)
    Capybara.reset_sessions!
  end

  config.before(:each) do
    DatabaseCleaner[:mongoid].start
  end

  config.after(:each) do
    DatabaseCleaner[:mongoid].clean
  end

  config.after(:suite) do
    Rails.cache.clear
  end

如果测试失败，请尝试放置sleep(5)AFTER并再次检查visit root_path
