And then this test is run to enforce a second-round 23provision that verifies the auto-update actually works. 24 25What does the failure of this test mean? 26 27If this test fails, any DUT with this build is likely going to require 28re-imaging from USB. We decided to add this test to bvt-inline and run it 29in parrallel with other tests, which means by the time this test reports 30failure, many duts in the pool will have been imaged with the bad build. 31 32We are taking the risk because 331) Blocking all testing until this test ran would impose a per-build 34 performance cost we don't want to pay. 352) History suggests that bugs of this sort are very rare. 363) We hope that in future, servo will be sufficiently reliable to offset 37 this kind of failure. 38""" 39 40 41from autotest_lib.client.common_lib import error 42from autotest_lib.client.cros import constants 43from autotest_lib.server import afe_utils 44from autotest_lib.server import utils as server_utils 45 46 47def run(machine): 48 # This test will try to access cautotest to get cros-label 49 # of the host and also update the label.
