Feature specs fail only on CircleCI or Codeship continuous integration services

selenium rspec capybara circleci codeship

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.
