[Autotest][Py3] Update autotestd and harness_autoserv To support python3, harness_autoserv and autotestd must be updated. autotestd needs to write line by line, rather than unbuffered, as its not supported for regular writing in python3. Additionally fds must be forced to False, as in python3 the default changes to True, breaking harness_autoserv Also, changing the cmd to include a sys.executable call, so that the autotest command is run in the same version of python as autotestd. BUG=chromium:990593 TEST=dummy_Pass (and some minor python3 testing) Change-Id: I7aab4c47a240e1fb9a303322355f688dc5cb7477 Reviewed-on: https://chromium-review.googlesource.com/c/chromiumos/third_party/autotest/+/2530529 Commit-Queue: Derek Beckett <email@example.com> Tested-by: Derek Beckett <firstname.lastname@example.org> Auto-Submit: Derek Beckett <email@example.com> Reviewed-by: Prathmesh Prabhu <firstname.lastname@example.org>
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.
