From a8075ff20b2046f847b91085aa27f2b336823337 Mon Sep 17 00:00:00 2001 From: Deepak S Date: Fri, 30 Dec 2016 09:21:22 -0800 Subject: Introducing Generic framework to do pre-deployment VNF & Network service testing This patch introduces the framework which is aligned with ETSI-TST001 This patch adds: 1. NetworkServiceTestCase introduces following functions --> setup --> Verify if infrastructure mapping can meet topology --> Load VNF models --> Fill traffic profile with information from topology --> Provision VNFs --> Run experiment (traffic) --> run -> Yardstick calls run() at intervals defined in the yaml and produces timestamped samples --> teardown --> Stop VNFs 2. TrafficProfile is a generic class to get traffic profile for a given testcase and select the traffic generator for testcase. 3. QueueFileWrapper is a class to send/recive cmds to vnf 4. GenericVNF is a generic class to instantiate VNF 5. GenericTrafficGen is a generic class to run/listen/verify traffic.
