servo: add ControlUnavailableError, has_control() This change adds its own error class for servo erros where the control is unavailable on the servod side. This simplifies some of the code as the autotest code occasionally requires bridges to ensure compatibility with older and newer servod versions. As the new error class inherits from TestFail, existing code should still work. Additionally, it adds a has_control() function to servo.py This now allows for two flows: - if the control is likely available, and just some lab compatibility issues i.e. slow updating of labstations are to be guarded against, try/except is probably the way to go - if the test should handle things differently whether a control is available or not, has_control() is likely the way to go. BUG=chromium:924434 TEST=test_that --autotest_dir . $DUP_IP power_ServoChargeStress.3loop // This test uses servo (thus goes through initiation flow) and uses a few // controls. To verify set/get still work as expected.

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.
