# usage: usbtuner-test.sh <test_case> [channel]
#
# To test repeated channel change, run:
#
# ./usbtuner-test.sh <1 or 3>
#
# To test watching a fixed channel, run:
#
# ./usbtuner-test.sh 2
#
# Case 2 uses the last-viewed channel by TV app. Give a channel number
# as a 2nd parameter if you want to use the channel for testing, like below:
#
# ./usbtuner-test.sh 2 6-1
#
# The script assumes that:
# 1) Browsing by keydown event circulates among the USB input channels only
# 2) When started, TV app should tune to one of the channels provided by the USB input
#
# The test result is logged in the doc: https://goo.gl/MsPBf7
