+# 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
