site_linux_router: truncate (not delete) uma-events We're removing this file, but that can confuse other daemons, which may then accidentally re-create the file with different owners/permissions, locking out non-root daemons. Rather than tease out the expected permissions or force all system daemons to configure the correct owners/permissions, let's just avoid deleting the file -- we can truncate it instead, which will retain its original permissions. Noticed in b:131906820, where shill is repeatedly complaining: ERR shill[646]: [ERROR:serialization_utils.cc(290)] /var/lib/metrics/uma-events: cannot open: Permission denied BUG=none TEST=run network_WiFi_* test; watch size, permissions of .../uma-events Change-Id: I8096917d385bab44444c8252acf702eab7a18407 Reviewed-on: https://chromium-review.googlesource.com/1600456 Commit-Ready: ChromeOS CL Exonerator Bot <chromiumos-cl-exonerator@appspot.gserviceaccount.com> Tested-by: Brian Norris <briannorris@chromium.org> Reviewed-by: Brian Norris <briannorris@chromium.org> Reviewed-by: Harpreet Grewal <harpreet@chromium.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.
