ruby-on-rails - Capybara/Poltergeist 无法到达服务器(连接被拒绝+ GET '/identify')

标签 ruby-on-rails ruby-on-rails-4 capybara poltergeist

更新

  • test.log 显示服务器正在响应我们的测试并呈现页面。
  • Poltergeist 失败并显示 Capybara::Poltergeist::StatusFailError:对“http://127.0.0.1:50712/computers”的请求无法到达服务器，请检查 DNS 和/或服务器状态 - 超时且未打开资源请求。

Poltergeist 无法连接到服务器。

我尝试过许多变体，包括:

  • 更长的超时时间(最多 300 秒)。
  • 将 Capybara.app_host 设置为 www.example.com、localhost 或 127.0.0.1。
  • 删除 phantomjs_options。
  • 从 static_controller.rb 中删除 force_ssl if: :ssl_configured?。
  • 渲染 users/sign_in 没有布局以消除外部 javascript。
  • 更改测试以调用 new_user_session_path、new_user_session_url 和 /users/sign_in。
  • 在运行测试(手动)之前运行 RAILS_ENV=test rake assets:precompile。

当我运行 rails s -e test 时，我可以打开 URL 127.0.0.1:3000/users/sign_in。

这是我遇到的错误:

✗ RAILS_ENV="test" ruby -I test test/integration/computers_test.rb -n /polt/
Started with run options -n /polt/ --seed 10197

之后的新日志:

  • 改用 Puma
  • 为Minitest添加代码
  • 在 test_helper.rb 中设置 Capybara.default_driver = :poltergeist 以停止错误地运行 rack_test。
  • 从测试中删除 Capybara.default_driver = Capybara.javascript_driver。

最佳答案

它显示试图访问“http://127.0.0.1/users/sign_in”的事实告诉您某处存在配置错误，因为那里应该有一个端口号(Capybara 从不在端口 80 上运行它的测试)。

首先，您设置了 Capybara.server_port = 3000。您是否需要这样做而不是让 Capybara 分配一个随机的空闲端口？如果您确实需要修复它，3000 是一个糟糕的选择，因为这会阻止您在测试运行时让您的开发实例运行。

其次，您设置了 Capybara.app_host。你真的需要设置这个吗？当您要针对外部站点进行测试，或者如果您有特殊的 IP 要求时，通常会使用它。如果您确实需要设置 app_host，您可能还需要设置 Capybara.always_include_port = true

所以两种解决方案

  1. 摆脱设置 app_host 和 server_port 并让 Capybara 管理它们

  2. 将您的固定服务器端口更改为 3000 以外的端口并添加 Capybara.always_include_port = true

此外，您可能还想阅读 https://github.com/teamcapybara/capybara#using-capybara-with-minitest因为在你的测试中设置 Capybara.default_driver = Capybara.javascript_driver 不会做你想做的事。
