#start_driver(server_url: nil, http_client_ops: { http_client: nil, open_timeout: 999_999, read_timeout: 999_999 }) ⇒ Selenium::WebDriver

Creates a new global driver and quits the old one if it exists. You can customise http_client as the following

Examples:


require 'rubygems'
require 'appium_lib_core'

# platformName takes a string or a symbol.

# Start iOS driver
opts = {
         caps: {
           platformName: :ios,
           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(self, opts) # create a core driver with `opts` and extend methods into `self`
@driver = @core.start_driver

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 }) —

    Options for http client

Options Hash (http_client_ops:):

  • :http_client (Hash) —

    Custom HTTP Client

  • :open_timeout (Hash) —
