使用 capybara/rails 运行 selenium 时，如何配置服务器? [英] When running selenium with capybara/rails, how do I configure the server?

问题描述

通常我在 3000 端口使用 rails 开发服务器.

Normally I use the rails dev server at port 3000.

Capybara/Cucumber 使用 Capybara.server_port = 31337.如果我从默认驱动程序切换到 selenium，它看起来会尝试连接端口 80.

Capybara/Cucumber uses Capybara.server_port = 31337. If I swap from the default driver to selenium, it looks like it tries to connect on port 80.

我正在努力理解:

• 使用 selenium 时，是否需要在测试环境中单独实例化一个测试服务器.
• 如果上述问题的答案是肯定的，我该如何做到这一点，以便我可以在 Web 驱动程序之间无缝切换，而无需不断更改?

如果有人有 env.rb 配置的示例可以帮助，请告诉我！

If someone has an example of a env.rb configuration that would help please let me know!

谢谢！

克里斯.

推荐答案

如果你使用selenium，你应该在测试环境中启动web server.您可以在与开发不同的端口上启动它.然后你应该配置 Capybara 使用那个端口:

If you use selenium, you should start web server in test environment. You can start it on a different port from development. Then you should configure Capybara to use that port:

  Capybara.run_server = true #Whether start server when testing
  Capybara.server_port = 8200
  Capybara.default_selector = :css #:xpath #default selector , you can change to :css
  Capybara.default_wait_time = 5 #When we testing AJAX, we can set a default wait time
  Capybara.ignore_hidden_elements = false #Ignore hidden elements when testing, make helpful when you hide or show elements using javascript
  Capybara.javascript_driver = :selenium #default driver when you using @javascript tag
  # Other option is:
  # Capybara.javascript_driver = :webkit

如果您不想每次在运行黄瓜场景之前都启动服务器，我建议您使用 capybara webkit 司机.所有 javascript 场景都将在后台运行.它也适用于持续集成服务器.

If you don't want to start server every time before you run your cucumber scenarios I suggest you to use capybara webkit driver. All javascript scenarios will run at background. It also will work on continuous integration server.

如果您在 Linux 平台上，capybara-webkit 需要 X 服务器才能运行.要设置它，您可以使用 headless gem.这是黄瓜的无头配置:

If you are on Linux platform, capybara-webkit requires an X server to run. To setup it you can use headless gem. Here is headless configuration for cucumber:

# place code below in features/support/headless.rb
if Capybara.current_driver == :webkit
  require 'headless'

  headless = Headless.new
  headless.start

  at_exit do
    headless.destroy
  end
end
