travis ci and selenium-webdriver unable to obtain stable firefox connection in 60 seconds (127.0.0.1:7055)

Question

I have a blog I'm working on and I added some javascript to make the form for the blog pop up when you click on new post. Everything works fine. I got tests working with minitest and capybara and I installed the gem selenium-webdriver everything works fine when I test it locally. However, when I push up to Github and travis-ci takes in my info and runs my tests it gives me this error

unable to obtain stable firefox connection in 60 seconds (127.0.0.1:7055)

I'm a little confused because I was getting that error locally until I updated to the gem selenium-webdriver to version 2.39.0. I just downloaded firefox so as far as I know everything is up to date. here is some of my files if that helps.

my test

feature "as a student I want a working blog so people can post" do
# this is line 10
  scenario "User can make a post", :js => true do
    dude_sign_up
    dude_log_in
    visit posts_path
    click_on "New Post"
    create_post
    page.must_have_content "Post was successfully created"
  end
# this is line 19

gemfile

group :development, :test do
  gem 'sqlite3'
  gem 'minitest-rails'
  gem 'launchy'
  gem 'coveralls', require: false
  gem 'minitest-rails-capybara'
  gem 'turn'
  gem 'pry'
  gem "selenium-webdriver", "~> 2.39.0"
end

does anyone understand why this works locally but not with travis-ci?

Answer 1

hey Reck you pointed me in the right direction; however, I found that the problem was in my .travis.yml file

if you go to

http://karma-runner.github.io/0.8/plus/Travis-CI.html

they will tell you that to set up travis to use firefox you need to add

before_script:
  - export DISPLAY=:99.0
  - sh -e /etc/init.d/xvfb start

to your travis file.

after changing my .travis.yml file to

language: ruby
rvm:
  - "2.0.0"
env:
  - DB=sqlite
before_script:
  - export DISPLAY=:99.0
  - sh -e /etc/init.d/xvfb start
script:
  - RAILS_ENV=test bundle exec rake db:migrate --trace
  - bundle exec rake db:test:prepare
  - rake minitest:features
bundler_args: --binstubs=./bundler_stubs

everything worked fine with travis

Try setting transactional_fixture to false in your rspec_spec.rb:

config.use_transactional_fixtures = false
