当使用capybara/rails运行selenium时，如何配置服务器?

问题描述

通常我在端口3000上使用Rails开发服务器.

Normally I use the rails dev server at port 3000.

水豚/黄瓜使用Capybara.server_port = 31337.如果我从默认驱动程序交换到selenium，则看起来它尝试在端口80上进行连接.

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.

我想了解:

• 使用硒时，是否需要在测试环境中单独实例化测试服务器.
• 如果上述问题的答案是肯定的，那么我该如何做到这一点，这样我就可以在Web驱动程序之间无缝切换而不必不断进行更改?

如果有人举了一个env.rb配置示例，可以帮助您，请告诉我！

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

谢谢！

推荐答案

如果使用硒，则应在测试环境中启动Web服务器.您可以在与开发不同的端口上启动它.然后，您应该将Capybara配置为使用该端口:

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方案之前都启动服务器，建议您使用 capybara webkit 驱动程序.所有JavaScript场景都将在后台运行.它还可以在持续集成服务器上工作.

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.

如果您使用的是Linux平台，则capybara-webkit需要运行X服务器.要进行设置，您可以使用无头 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
