node

Installs and configures a Selenium Node as service on Linux and a GUI service on Mac OS X and Windows.

• Firefox browser must be installed outside of this cookbook.
• Linux nodes without a physical monitor require a headless display (e.g., xvfb, x11vnc, etc...) and must be installed and configured outside this cookbook.
• Mac OS X/Windows nodes must run as a GUI service and that requires a username and password for automatic login. Note that Windows password is stored unencrypted under windows registry HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon and Mac OS X password is stored encrypted under /etc/kcpassword but it can be easily decrypted.

Attributes

• node['selenium']['node']['servicename'] - The name of the service. Default selenium_node.
• node['selenium']['node']['host'] - Default ip.
• node['selenium']['node']['port'] - Default 5555.
• node['selenium']['node']['jvm_args'] - Default nil.

• node['selenium']['node']['maxSession'] - Default 5.
• node['selenium']['node']['register'] - Default true.
• node['selenium']['node']['registerCycle'] - Default 5000.
• node['selenium']['node']['hubPort'] - Selenium-grid hub hostname. Default 4444.
• node['selenium']['node']['hubHost'] - Selenium-grid hub port. Default ip.
• node['selenium']['node']['capabilities'] - Based on capabilities. Default [].
• node['selenium']['node']['additional_args'] - Default [].
• node['selenium']['node']['display'] - Default :0.
• Mac OS X/Windows only - Set both username and password to run as a GUI service:
  • username - Default nil.
  • password - Default nil. Note that Windows password is stored unencrypted under windows registry HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon and Mac OS X password is stored encrypted under /etc/kcpassword but it can be easily decrypted.
  • domain - Optional for Windows only. Default nil.

    seleniumProtocol: 'WebDriver'
  },
  {
    browserName: 'htmlunit',
    maxInstances: 1,
    platform: 'ANY',
    seleniumProtocol: 'WebDriver'
  }
]
