From 8800f732f868bf54da8adba05e38bd2477895ca5 Mon Sep 17 00:00:00 2001 From: Dave Wallace Date: Thu, 31 Aug 2023 00:47:44 -0400 Subject: tests: refactor asf framework code - 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 --- test/test_wireguard.py | 39 +++++++++++++++++++++++++-------------- 1 file changed, 25 insertions(+), 14 deletions(-) (limited to 'test/test_wireguard.py') diff --git a/test/test_wireguard.py b/test/test_wireguard.py index 4e9679283c4..ede02f109fa 100644 --- a/test/test_wireguard.py +++ b/test/test_wireguard.py @@ -7,9 +7,8 @@ import os from hashlib import blake2s from config import config -from scapy.packet import Packet from scapy.packet import Raw -from scapy.layers.l2 import Ether, ARP +from scapy.layers.l2 import Ether from scapy.layers.inet import IP, UDP from scapy.layers.inet6 import IPv6 from scapy.layers.vxlan import VXLAN @@ -30,15 +29,11 @@ from cryptography.hazmat.primitives.serialization import ( PublicFormat, NoEncryption, ) -from cryptography.hazmat.primitives.hashes import BLAKE2s, Hash -from cryptography.hazmat.primitives.hmac import HMAC -from cryptography.hazmat.backends import default_backend from noise.connection import NoiseConnection, Keypair from Crypto.Cipher import ChaCha20_Poly1305 from Crypto.Random import get_random_bytes -from vpp_ipip_tun_interface import VppIpIpTunInterface from vpp_interface import VppInterface from vpp_pg_interface import is_ipv6_misc from vpp_ip_route import VppIpRoute, VppRoutePath @@ -46,7 +41,7 @@ from vpp_l2 import VppBridgeDomain, VppBridgeDomainPort from vpp_vxlan_tunnel import VppVxlanTunnel from vpp_object import VppObject from vpp_papi import VppEnum -from framework import is_distro_ubuntu2204, is_distro_debian11, tag_fixme_vpp_debug +from asfframework import tag_run_solo, tag_fixme_vpp_debug from framework import VppTestCase from re import compile import unittest @@ -513,6 +508,7 @@ def is_handshake_init(p): @unittest.skipIf( "wireguard" in config.excluded_plugins, "Exclude Wireguard plugin tests" ) +@tag_run_solo class TestWg(VppTestCase): """Wireguard Test Case""" @@ -538,10 +534,6 @@ class TestWg(VppTestCase): @classmethod def setUpClass(cls): super(TestWg, cls).setUpClass() - if (is_distro_ubuntu2204 == True or is_distro_debian11 == True) and not hasattr( - cls, "vpp" - ): - return try: cls.create_pg_interfaces(range(3)) for i in cls.pg_interfaces: @@ -931,7 +923,22 @@ class TestWg(VppTestCase): NUM_TO_REJECT = 10 init = peer_1.mk_handshake(self.pg1, is_ip6=is_ip6) txs = [init] * (HANDSHAKE_NUM_BEFORE_RATELIMITING + NUM_TO_REJECT) - rxs = self.send_and_expect_some(self.pg1, txs, self.pg1) + + # TODO: Deterimine why no handshake response is sent back if test is + # not run in as part of the test suite.
