For now the test keeps track of video bandwidth estimation and plots it using google visualization libraries after the test is concluded. There is also scripts to run a test and record the tcpdump.

# This script is used to record a tcp dump of running a loop back test.
|
|
# Example use case:
|
|
#
|
|
# $ ./run-server.sh & # spawns a server to serve the html pages
|
|
# # on localhost:8080
|
|
#
|
|
# (recording 3 tests with 5mins and bitrates 1mbps, 2mbps and 3mbps)
|
|
# $ sudo -v # Caches sudo credentials needed
|
|
# # for tcpdump
|
|
# $ export INTERFACE=eth1 # Defines interface to record packets
|
|
# $ export CHROME_UNDER_TESTING=./chrome # Define which chrome to run on tests
|
|
# $ export TEST="http://localhost:8080/loopback_test.html?auto-mode=true"
|
|
# $ record-test.sh ./record1.pcap "$TEST&duration=300&max-video-bitrate=1000"
|
|
# $ record-test.sh ./record2.pcap "$TEST&duration=300&max-video-bitrate=2000"
|
|
# $ record-test.sh ./record3.pcap "$TEST&duration=300&max-video-bitrate=3000"
|
|
|
|
# Indicate an error and exit with a nonzero status if any of the required
|
|
# environment variables is Null or Unset.
