DOC = """
This wrapper test automates the process of power measurement with powerlog tool
while running a client test. Please check the client test's control file for any
hardware requirement, e.g. no AC power, no Ethernet.

This test makes the following assumptions:
1. Sweetberry config files are in directory
/usr/lib64/python2.7/site-packages/servo/data/
For example,
/usr/lib64/python2.7/site-packages/servo/data/eve_rev7.board
/usr/lib64/python2.7/site-packages/servo/data/eve_rev7.scenario

2. The workstation (or where the autotest is kicked off from) should be in same
timezone with the DUT.

Sample usage:
test_that <ip address of DUT> power_PowerlogWrapper --args \
'test=power_LoadTest.fast sweetberry_interval=1 sweetberry_config=eve_rev7'

What are the parameters:
test: the client test to run in wrapper test; DUT power is measured during this
      client test; required.
sweetberry_interval: number of seconds between each Sweetberry measurement;
                     optional.
sweetberry_config: use [].board and [].scenario as configuration file for
                   Sweetberry measurement; optional.
sweetberry_serial: serial number of sweetberry to use; If not supplied use
                   the first sweetberry found; optional.
pdash_note: User supplied note to tag the specific test; optional.
