From 5b6b314d4c36dbe6e8da4e7d2d2813356397ef77 Mon Sep 17 00:00:00 2001 From: "jose.lausuch" Date: Fri, 7 Jul 2017 12:44:36 +0200 Subject: New python script to check openstack deployment This is a crucial part of functest env prepare. The former check_os.sh is missing some error control and is sometimes trying to connect to an empty endpoint if the sed/awk commands were wrong. This python script is more robust in that sense. You can see an example of execution in [1].
