我的基本功能测试在本地可以正常通过，但在CircleCI和Codeship上失败。正在失败的测试:
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
这两个测试都在设置页面期望值的第一行失败了（分别为
expect( page ).to have_content "LOG IN"和click_link "Sign up"），错误提示页面HTML完全为空白：expected to find text "LOG IN" in ""
我在CircleCI上保存了截图，它们显示了一个完全的空白页面。
这里有个有趣的事情。我尝试通过使用VNC在Circle上运行/观察spec文件来调试问题。当我a)为测试设置driver: :selenium，b)在测试之前加入1或2个sleep，并c)通过在VNC上SSH到他们的服务器后手动运行测试时，我可以看到Selenium中的测试运行（它们在VNC中打开浏览器），并且它们完美地通过了测试。
然而，在VNC之外，这些测试在两台CI服务器中始终失败。无论是否有大量的sleep和driver: :selenium。对于常规的CircleCI/Codeship服务器和他们的VCN/本地测试环境之间存在什么差异引起了这种差异，您是否有任何想法？我联系了CircleCI的人，但他们暂时束手无策。
如果相关的话，我正在运行Ruby 2.2.0、Rails 4.2、Capybara 2.4.4、Capybara-Webkit 1.4.1和Selenium-Webdriver 2.44.0
