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
- Asyc lockup for device changes.
Device UI
- Navigate to localhost:4723/device-farm once the appium server is started.
User can block/unblock devices from Dashboard manually. These devices will not be picked up for automation.
Once automation picks the device user cannot manually unblock, its responsbile of the automation script.
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-ios-device-type | No | Types of ios devices to include | both | both ,simulated ,real , For example: If you want to run only against iOS simulator then specify --plugin-device-farm-ios-device-type=simulated |
--plugin-device-farm-android-device-type | No | Types of android devices to include | both | both ,simulated ,real , For example: If you want to run only against android emulator then specify --plugin-device-farm-android-device-type=simulated |
plugin-device-farm-skip-chrome-download | No | Downloads require chromedriver for web testing | true | false Setting to false will download required chromedriver for web testing on chrome |
plugin-device-farm-hub | No | HUB IP address and port the node should register | None | hub: "http://hubhost:hubport" , If you want to run tests distributed across remote and local machine |
plugin-device-farm-max-sessions | No | Limit how many sessions can be active at a time. This is useful when you need limit sessions based on host machine resource availability. | None | <number> e.g. 8 |
plugin-device-farm-derived-data-path | No | DriveDataPath of WDA to speed iOS test run. | None | {'simulator': 'PathtoDrivedDataPath', 'device': 'PathtoDrivedDataPath'} |
plugin-device-farm-adb-remote | No | ADB Remote host and port as array | None | ["remoteMachine1IP:adbPort", "remoteMachine2IP:adbPort"] |
Above cli arguments can also be set from config.json file Refer here
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:platformName | Requests asession for the provided platform name. Valid options are iOS , tvOS , or Android , ex: 'appium:platformName': tvOS |
appium:platformVersion | This capability is used to filter devices/simulators based on SDK. Only devices/simulators that are an exact match with the platformVerson would be considered for test run. appium:platformVersion is optional argument. ex: 'appium:platformVersion': 16.1.1 |
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 |
Custom chrome binary url
set the new URL to CHROMEDRIVER_CDNURL
environment variable:
CHROMEDRIVER_CDNURL=http://npm.taobao.org/mirrors/chromedriver appium server -ka 800 --use-plugins=device-farm --config ./server-config.json -pa /wd/hub
Notes
- 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.
