Examples:


require 'rubygems'
require 'appium_lib_core'

# platformName takes a string or a symbol.

# Start iOS driver
opts = {

           platformVersion: '11.0',
           deviceName: 'iPhone Simulator',
           automationName: 'XCUITest',
           app: '/path/to/MyiOS.app'
         },
         appium_lib: {
           wait: 20,
           wait_timeout: 20,
           wait_interval: 0.3,
         }
       }

@core = Appium::Core.for(opts) # create a core driver with `opts` and extend methods into `self`

Parameters:

  • server_url (String) (defaults to: nil) —

    Custom server url to send to requests. Default is “127.0.0.1:4723/wd/hub”.

  • http_client_ops (Hash) (defaults to: { http_client: nil, open_timeout: 999_999, read_timeout: 999_999 }) —
