travis ci和selenium-webdriver无法在60秒内获得稳定的firefox连接(127.0.0.1:7055)

Question

我有一个我正在研究的博客,我添加了一些javascript,以便在您点击新帖子时弹出博客的表单.一切正常.我使用minitest和capybara进行测试,我安装了gem selenium-webdriver,当我在本地测试时,一切正常.但是,当我推送到Github并且travis-ci接收我的信息并运行我的测试时,它给了我这个错误

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

我有点困惑,因为我在本地得到了这个错误,直到我更新到gem selenium-webdriver到版本2.39.0.我刚刚下载了firefox,据我所知,一切都是最新的.这是我的一些文件,如果这有帮助.

我的考试

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

的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

.travis.yml文件

language: ruby

  - DB=sqlite
script:
  - RAILS_ENV=test bundle exec rake db:migrate --trace
  - bundle exec rake db:test:prepare

有谁知道为什么这在本地工作但不与travis-ci一起工作？

Answer 1

嘿雷克你指出我正确的方向; 但是,我发现问题出在我的.travis.yml文件中

如果你去

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

他们会告诉你要设置travis使用firefox你需要添加

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

到您的travis文件.

将我的.travis.yml文件更改为

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

一切都很好用特拉维斯
