           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'
@driver = @core.start_driver server_url: "http://127.0.0.1:8000/wd/hub"

# Attach custom HTTP client
@driver = @core.start_driver server_url: "http://127.0.0.1:8000/wd/hub",
