- Make framework.py classes a subset of asfframework.py classes - Remove all packet related code from asfframework.py - Add test class and test case set up debug output to log - Repatriate packet tests from asf to test directory - Remove non-packet related code from framework.py and inherit them from asfframework.py classes - Clean up unused import variables - Re-enable BFD tests on Ubuntu 22.04 and fix intermittent test failures in echo_looped_back testcases (where # control packets verified but not guaranteed to be received during test) - Re-enable Wireguard tests on Ubuntu 22.04 and fix intermittent test failures in handshake ratelimiting testcases and event testcase - Run Wiregard testcase suites solo - Improve debug output in log.txt - Increase VCL/LDP post sleep timeout to allow iperf server to finish cleanly. - Fix pcap history files to be sorted by suite and testcase and ensure order/timestamp is correct based on creation in the testcase. - Decode pcap files for each suite and testcase for all errors or if configured via comandline option / env var - Improve vpp corefile detection to allow complete corefile generation - Disable vm vpp interfaces testcases on debian11 - Clean up failed unittest dir when retrying failed testcases and unify testname directory and failed linknames into framwork functions Type: test Change-Id: I0764f79ea5bb639d278bf635ed2408d4d5220e1e Signed-off-by: Dave Wallace <dwallacelf@gmail.com>
