Welcome to Mobly

Latest release Build Status

Mobly is a Python-based test framework that specializes in supporting test cases that require multiple devices, complex environments, or custom hardware setups.

Here are some example use cases:

  • P2P data transfer between two devices
  • Conference calls across three phones
  • Wearable device interacting with a phone
  • Internet-Of-Things devices interacting with each other
  • Testing RF characteristics of devices with special equipment
  • Testing LTE network by controlling phones, base stations, and eNBs

Mobly can support many different types of devices and equipment, and it's easy to plug your own device or custom equipment/service into Mobly.

Mobly comes with a set of libs to control common devices like Android devices.

While developed by Googlers, Mobly is not an official Google product.


Mobly requires python 3.11 or newer.

Mobly tests could run on the following platforms:

  • Ubuntu 14.04+
  • MacOS 10.6+
  • Windows 7+

System dependencies

  • adb (1.0.40+ recommended)
  • python3.11+


You can install the released package from pip

pip install mobly

or install from the source to use the bleeding edge:

git clone
cd mobly
pip install -e .

You may need sudo for the above commands if your system has certain permission restrictions.


Mobly Snippet

The Mobly Snippet projects let users better control Android devices.

  • Mobly Snippet Lib: used for triggering custom device-side code from host-side Mobly tests. You could use existing Android libraries like UI Automator and Espresso.
  • Mobly Bundled Snippets: a set of Snippets to allow Mobly tests to control Android devices by exposing a simplified version of the public Android API suitable for testing.
