Codeship 在 rails-devise-roles 测试中中断

Question

当在 Codeship 的 CI 中运行时，rails-devise-roles 应用程序对 user-delete-spec.rb 和 user-edit-spec.rb 的 Selenium 测试似乎中断了。 rspec 在我的本地机器上运行良好，但在 Codeship 中中断。

我得到的rspec输出如下：

Failures:

1) User delete user can delete own account
Failure/Error: visit edit_user_registration_path(user)

Finished in 23.21 seconds (files took 2.99 seconds to load)
31 examples, 3 failures

Failed examples:

rspec ./spec/features/users/user_delete_spec.rb:18 # User delete user can delete own account
rspec ./spec/features/users/user_edit_spec.rb:18 # User edit user changes email address
rspec ./spec/features/users/user_edit_spec.rb:45 # User edit user cannot cannot edit another user's profile

这是失败场景之一的示例：

scenario 'user can delete own account' do
    # skip 'skip a slow test' [removed from the original file]
    user = FactoryGirl.create(:user)
    login_as(user, :scope => :user)
    visit edit_user_registration_path(user)
    click_button 'Cancel my account'
    page.driver.browser.switch_to.alert.accept
    expect(page).to have_content I18n.t 'devise.registrations.destroyed'
end

这里出了什么问题，我该如何修改才能使测试通过？（需要澄清的是，我在这些页面上的本地部署以及基于 rails-devise-roles 的应用程序的 Heroku 实时部署都没有错误 500。）

Answer 1

联系了 Codeship 支持，他们非常乐于助人，并告诉我这是 Firefox 和适用于 Firefox 的 geckodriver 的问题，需要在 Codeship VM 上更新。如果其他人也有这个问题，使其工作的代码如下：

export FIREFOX_VERSION=53.0.3
curl -sSL https://raw.githubusercontent.com/codeship/scripts/master/packages/firefox.sh | bash -s
export GECKODRIVER_VERSION=0.17.0
source /dev/stdin <<< "$(curl -sSL https://raw.githubusercontent.com/codeship/scripts/master/languages/rust.sh)"
curl -sSL https://raw.githubusercontent.com/codeship/scripts/master/packages/geckodriver.sh | bash -s

非常感谢 Codeship 支持团队的 Joe Siewert 为我解决了这个问题！
