Appium Device Farm

This is an Appium 2.0 plugin designed to manage and create driver sessions on available devices.

Project README

appium-device-farm Node.js CI

This is an Appium plugin designed to manage and create driver session on connected android devices and iOS Simulators.

Why Appium Device Farm?

  • Automatically detects connected Android, iOS Simulators and Real devices before session creation and maintains it in device pool.
  • Dynamically allocates a free device from device pool while creating driver session.
  • Updates the device pool with a new device during test execution.
  • Allocates random ports for parallel execution.

Device UI

  • Navigate to localhost:4723/device-farm once the appium server is started.


Appium version 2.0 - Tested with 2.0.0-beta.21

Installation - Server

Install the plugin using Appium's plugin CLI, either as a named plugin or via NPM:

appium plugin install --source=npm appium-device-farm
appium plugin install --source=npm appium-dashboard

Installation - Client

No special action is needed to make things work on the client side.


The plugin will not be active unless turned on when invoking the Appium server:

appium server -ka 800 --use-plugins=device-farm,appium-dashboard  -pa /wd/hub --plugin-device-farm-platform=android

Arguments options: 

* Android - If you want to use only Android devices for parallel execution.
* iOS - If you want to use only iOS devices and simulator for parallel execution.
* both - If you want to use both android and iOS devices for parallel execution.


Capability Name Description
appium:iPhoneOnly Allocate only iPhone simulators for execution when to true. Default value is false.
appium:iPadOnly Allocate only iPad simulators for execution when to true. Default value is false.
appium:deviceAvailabilityTimeout When create session requests are more than available connected devices, plugin waits for a certain interval for device availability before it timeout. Default value is 180000 milliseconds.
appium:deviceRetryInterval When create session requests are more than available connected devices, plugin polls for device availability in certain intervals. Default value is 10000 milliseconds.


Server logs will be as below:
