DeviceFarm

A command-line tool for using AWS Device Farm. Key features:

• Easily manage device pools through a config file in your repo.
• Run your build and upload artifacts & tests to Device Farm.
• Gives you a URL to jump straight to your test results in the AWS Console.

Install

For OS X users, we recommend installing via Homebrew:

brew tap ride/devicefarm
brew install devicefarm
# all set!
devicefarm --version

For other platforms, devicefarm is distributed as a binary. Simply go to Releases and download the latest binary for your platform.

Setup

First, you will need an AWS user who has permission to access Device Farm. It is recommended to setup a separate user for this purpose. Once you have that, create a file ~/.devicefarm.json with contents like this:

{
  "AWS_ACCESS_KEY_ID": "... your key ...",
  "AWS_SECRET_ACCESS_KEY": "... your secret ..."
}

Second, you should setup a devicefarm.yml config in your repo, like this one.

Features

Only Android instrumentation tests are supported at the moment. See future work.

Run instrumentation tests on Device Farm

# go into your android project
$ cd /path/to/android-app/

# run tests. the output is a URL you can visit to view your test results.
$ devicefarm run
...

Update device pools

If you update your device pools in devicefarm.yml you can run tests on different sets of devices. See "List devices" below for how to find device identifiers.

# go into your android project
$ cd /path/to/android-app/

# if you checkout a branch, device pools will be tied only to that branch
$ git checkout -b my-test-branch

# now edit devicefarm.yml...
# you can change the default config, OR specify overrides for your specific branch

# now just create another run
$ devicefarm run

List devices

This way you can find devices you want to add to your device pools.

# list all devices
$ devicefarm devices
(arn=device:306ABA42C96044ED9AC3EE8684B56C54) Apple iPad Mini 1st Gen
(arn=device:5F9CEB47606A4709879003E11BEAFB08) Samsung Galaxy Tab 2 10.1 (WiFi)
...

# list all devices matching "mini"
$ devicefarm devices "mini"
(arn=device:306ABA42C96044ED9AC3EE8684B56C54) Apple iPad Mini 1st Gen
(arn=device:5C748437DC1C409EA595B98B1D7A8EDD) Samsung Galaxy S3 Mini (AT&T)
...

# list all android devices matching "mini"
# there is also an --ios flag :)
$ devicefarm devices --android "mini"
(arn=device:5C748437DC1C409EA595B98B1D7A8EDD) Samsung Galaxy S3 Mini (AT&T)
(arn=device:20766AF83D3A4FEF977643BFCDC2CE3A) Samsung Galaxy S4 mini (Verizon)

Limitations, bugs & future work

See our issue tracker for known bugs, improvements, and maintenance work.

Right now only Android instrumentation tests are supported. As part of our 2.0 Milestone we'll be adding:

• Support for all test types (including iOS and web).
• Commands to help setup AWS credentials and devicefarm.yml config.
• A Homebrew tap so OS X users can install and update using brew.
• Polishing existing commands and config to make them easier to use.
