From de6fc4b670fc42fc96f27f375fbcf7a099629434 Mon Sep 17 00:00:00 2001 From: Martin Klozik Date: Thu, 18 May 2017 10:18:38 +0100 Subject: tests: Improvement of step driven testcases A set of improvements was introduced to enhance step driven testcases capabilities. Details: * delay among test steps is configurable by TEST_STEP_DELAY parameter * step driven tool function exec was renamed to exec_shell * new step driven tool function exec_python was introduced to execute a python code * new step driven object sleep was introduced to pause test execution for defined number of seconds. * fixed bug in settings.validate_getValue() to correctly validate access of parameters modified by TEST_PARAMS * new #PARAM() macro was introduced to allow references among configuration parameters * multistream support has been added into ixnetrfc2544v2.tcl, which is used for tunneling protocols test (op2p deployment) * fixed bug in op2p deployment to list interfaces and flows from both bridges involved in the test * test report updated to state exact rfcxxxx type of traffic type, e.g. rfc2544_continuous * test report of step driven testcases was updated to contain measured values from traffic generator in CSV report * method for ovs flow comparison was modified to normalize IPv4 CIDR network addr (e.g. 10.0.0.5/8 => 10.0.0.0/8) JIRA: VSPERF-512 Change-Id: Ib4f38dcdfbf3820dd766b25520da0ad0c81f3293 Signed-off-by: Martin Klozik Reviewed-by: Al Morton Reviewed-by: Christian Trautman Reviewed-by: Sridhar Rao Reviewed-by: Trevor Cooper Reviewed-by: Ciara Loftus --- src/ovs/ofctl.py | 15 +++++++++++++-- 1 file changed, 13 insertions(+), 2 deletions(-) (limited to 'src') diff --git a/src/ovs/ofctl.py b/src/ovs/ofctl.py index f0d116da..64d54466 100644 --- a/src/ovs/ofctl.py +++ b/src/ovs/ofctl.py @@ -22,6 +22,7 @@ https://github.com/openstack/neutron/blob/6eac1dc99124ca024d6a69b3abfa3bc69c7356 import logging import string import re +import netaddr from tools import tasks from conf import settings @@ -31,6 +32,9 @@ _OVS_CMD_TIMEOUT = settings.getValue('OVS_CMD_TIMEOUT') _CACHE_FILE_NAME = '/tmp/vsperf_flows_cache' +# only simple regex is used; validity of IPv4 is not checked by regex +_IPV4_REGEX = r"([0-9]{1,3}(\.[0-9]{1,3}){3}(\/[0-9]{1,2})?)" + class OFBase(object): """Add/remove/show datapaths using ``ovs-ofctl``.
