This commit updates the Sink testing script to automatically handle the
connector-flipping portion of the test, which I had to perform manually
up until now. It also shortens the procedure, and tests that the
configuration is maintained after re-connecting the device. And now it
should be possible to make another testing procedure inheriting from
this one for the upcoming automated test jig.
If there's a single PD Buddy Sink attached, it's pretty clear which one
we want to be testing. As such, the testing script shouldn't require
the device to be specified if it can find exactly one Sink. This commit
does just that, and like so, I will almost never have to figure out
which device file I need when testing a Sink again.
To replace my old Sink testing system (GNU Screen and a text file with
the commands to send to the Sink), I wrote a Python script that tests
the Sink automatically. The only thing I have to do (assuming the test
is successful) is press Enter a few times while watching a voltmeter's
display. A basic testing script could be useful to other people, so I'm
including it in this Python package.
I have a vague plan to integrate this with Kaylee at some point so I
don't even have to press Enter, but that will have to wait until Kaylee
has menu support.
