My very basic feature specs are passing just fine locally but failing on CircleCI and Codeship. The tests that are failing:

require 'spec_helper'

describe 'Authentication' do

  describe "sign in" do
    it "is the landing page for non-authenticated users" do
      user = create(:user)
      visit root_path

      expect( page ).to have_content 'LOG IN' # On sign-in page
      fill_in 'Email', with: user.email
      fill_in "Password", with: user.password
      click_button 'Sign in'

      expect( current_path ).to eq user_path(user)
    end
  end

  describe 'registration' do
    it "allows new users to register" do
      visit root_path

      click_link 'Sign up'
      fill_in 'Email', with: 'myfake@email.com'
      fill_in 'Password', with: 'password'
      fill_in 'Password confirmation', with: 'password'
      fill_in 'First name', with: 'John'
      fill_in 'Last name', with: 'Doe'
      click_button "Sign up"

      expect( current_path ).to include '/users/'
      expect( page ).to have_content "Welcome! You have signed up successfully."
    end
  end
end

The tests both fail on the first lines where they set expectations of the pages (expect( page ).to have_content "LOG IN" and click_link "Sign up", respectively), with errors suggesting the page HTML is completely blank:

expected to find text "LOG IN" in ""

I saved screenshots on CircleCI, and they indeed show a completely blank page.

Here's where it gets interesting. I tried debugging the problem by running/watching the specs on Circle using a VNC. When I a) set driver: :selenium for the tests, b) add a sleep 1 or two to the tests before testing the page expectations, and c) manually run the test after SSHing into their servers with the VNC, I can see the tests run in Selenium (they open a browser in the VNC) and they pass perfectly.

Outside of the VNC, however, the tests fail consistently in both CI servers. With or without tons of sleeps and driver: :selenium. Any ideas what could be causing this discrepancy between the regular CircleCI/Codeship servers and their VCN/my local test environment? I got in touch with the folks at CircleCI, but they're stumped for the moment.

If relevant, I'm running Ruby 2.2.0, Rails 4.2, Capybara 2.4.4, Capybara-Webkit 1.4.1, and Selenium-Webdriver 2.44.0

I can think of a couple of things to try:

  • If you want to get your specs to run headless, try using poltergeist rather than capybara-webkit. poltergeist has several advantages which I described here: https://stackoverflow.com/a/24108439/634576
  • Selenium might just be a distraction, but, if you want to get it to work, be sure that your CI environment has the right version of Firefox. Each version of selenium-webdriver seems to need a narrow range of versions of Firefox. On CircleCI, you can configure circle.yml to install a specific version of Firefox. Right now we use selenium-webdriver 2.46.2 and Firefox 39.0.3, installed with the following in circle.yml:

    dependencies:
      pre:
        - sudo apt-get update; sudo apt-get install firefox=39.0.3+build2-0ubuntu0.12.04.1
    

    I don't know about Codeship.

I have experienced instability of my Selenium tests on CircleCI until I came across this post https://discuss.circleci.com/t/selenium-tests-timing-out/7765/2

After adding:

machine:
  environment:
    DBUS_SESSION_BUS_ADDRESS: /dev/null

to my circle.yml, my tests have become stable.
