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 global device pool.
• Dynamically allocates a free device from global device pool while creating driver session.
• Dynamically updates global device pool when new device is detected, or an existing device is removed during the test execution.
• Dynamically updates global device pool by polling for connected devices every 10 seconds.
• Allocates random ports for parallel execution.

Device UI

• Navigate to localhost:3333 once the first session is created.

Prerequisite

Appium version 2.0

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

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:

appium --plugins=device-manager

Capabilities

By default global devices pool includes all the iOS simulators.

To allocate only iPhone simulators set below capability to true,

capabilities.setCapability("appium:iPhoneOnly", "true");

To allocate only iPad simulators set below capability to true,

capabilities.setCapability("appium:iPadOnly", "true");

Example

Server logs will be as below:
