# Autotest: Automated integration testing for Android and Chrome OS Devices
|
|
|
|
Autotest is a framework for fully automated testing. It was originally designed
|
|
to test the Linux kernel, and expanded by the Chrome OS team to validate
|
|
complete system images of Chrome OS and Android.
|
|
|
|
Autotest is composed of a number of modules that will help you to do stand alone
|
|
tests or setup a fully automated test grid, depending on what you are up to.
|
|
A non extensive list of functionality is:
|
|
|
|
* A body of code to run tests on the device under test. In this setup, test
|
|
logic executes on the machine being tested, and results are written to files
|
|
for later collection from a development machine or lab infrastructure.
|
|
|
|
* A body of code to run tests against a remote device under test. In this
|
|
setup, test logic executes on a development machine or piece of lab
|
|
infrastructure, and the device under test is controlled remotely via
|
|
SSH/adb/some combination of the above.
|
|
|
|
* Developer tools to execute one or more tests. `test_that` for Chrome OS and
|
|
`test_droid` for Android allow developers to run tests against a device
|
|
connected to their development machine on their desk. These tools are written
|
|
so that the same test logic that runs in the lab will run at their desk,
|
|
reducing the number of configurations under which tests are run.
|
|
|
|
* Lab infrastructure to automate the running of tests. This infrastructure is
|
|
capable of managing and running tests against thousands of devices in various
|
|
lab environments. This includes code for both synchronous and asynchronous
|
|
scheduling of tests. Tests are run against this hardware daily to validate
|
|
every build of Chrome OS.
|
|
|
|
* Infrastructure to set up miniature replicas of a full lab. A full lab does
|
|
entail a certain amount of administrative work which isn't appropriate for
|
|
a work group interested in automated tests against a small set of devices.
|
|
Since this scale is common during device bringup, a special setup, called
|
|
Moblab, allows a natural progressing from desk -> mini lab -> full lab.

## Run some autotests
|
|
|
|
See the guides to `test_that` and `test_droid`:
|
|
|
|
[test\_droid Basic Usage](docs/test-droid.md)
|
|
|
|
[test\_that Basic Usage](docs/test-that.md)
|
|
|
|
## Write some autotests
|
|
|
|
See the best practices guide, existing tests, and comments in the code.

## Grabbing the latest source
|
|
|
|
`git clone https://chromium.googlesource.com/chromiumos/third_party/autotest`

## Hacking and submitting patches
|
|
|
|
See the coding style guide for guidance on submitting patches.

## Pre-upload hook dependencies
|
|
|
|
You need to run `utils/build_externals.py` to set up the dependencies
|
|
for pre-upload hook tests.
