18This wrapper test automates the process of power measurement with powerlog tool
19while running a client test. It also uses Servo v4 to control charging and
20discharging the DUT. Please check the client test's control file for any
21hardware requirement, e.g. no AC power, no Ethernet.
22
23This test makes the following assumptions:
241. Sweetberry config files are in directory
25/usr/lib64/python2.7/site-packages/servo/data/
26For example,
27/usr/lib64/python2.7/site-packages/servo/data/eve_rev7.board
28/usr/lib64/python2.7/site-packages/servo/data/eve_rev7.scenario
29
302. The workstation (or where the autotest is kicked off from) should be in same
31timezone with the DUT.
32
333. Servod is started for the Servo v4 connected to the DUT. AC should be plugged
34into the Servo v4.
35
36Sample usage:
37test_that <ip address of DUT> power_PowerlogWrapper --args \
38'test=power_LoadTest.fast servo_host=localhost servo_port=9999 sweetberry_interval=1 sweetberry_config=eve_rev7'
39
40What are the parameters:
41test: the client test to run in wrapper test; DUT power is measured during this
42      client test; required.
43servo_host: host of servod instance; required.
44servo_port: port that the servod instance is on; required.
45sweetberry_interval: number of seconds between each Sweetberry measurement;
46                     optional.
47sweetberry_config: use [].board and [].scenario as configuration file for
48                   Sweetberry measurement; optional.
49sweetberry_serial: serial number of sweetberry to use; If not supplied use
50                   the first sweetberry found; optional.
51pdash_note: User supplied note to tag the specific test; optional.
