appium-device-farm

appium-device-farm

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.
• Remote execution

Device UI

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

Prerequisite

Appium version 2.0.0-beta.43

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.

Activation

The plugin will not be active unless turned on when invoking the Appium server. See "Argument options" below

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

You can also pass all the arguments in a config file. Refer here

appium server -ka 800 --use-plugins=device-farm --config ./server-config.json -pa /wd/hub

Argument options

These arguments are set when you launch the Appium server, with this plugin installed.

Argument	Required	Description	Default	Options
plugin-device-farm-platform	Yes	Platform to run tests against for parallel execution	None	both,ios,android
plugin-device-farm-device-types	No	Types of devices to include	both	both,simulated,real
plugin-device-farm-remote	No	Whether or not to include simulators/real devices from remote machine	None	remote: ["http://remotehost:remoteport"], If you want to run tests distributed across remote and local machine remote: ["http://remotehost:remoteport", "http://127.0.0.1"]

Capabilities

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.
appium:udids	Comma separated list of device udid's to execute tests only on specific devices appium:udids: device1UDID,device2UDID
appium:minSDK	This capability is used to filter devices/simulators based on SDK. Devices/Simulators with SDK greater then or equal to minSDK would only be considered for test run. appium:minSDK is optional argument. ex: 'appium:minSDK': 15

Notes

1. If there is no activity on a session for more then 100 seconds, device allocated to respective session would be unblocked and made available for new session requests.

Remote Execution
