From b6921bcb122d9f2f4b17afd78b7bf8b5bc228212 Mon Sep 17 00:00:00 2001 From: Christian Trautman Date: Tue, 9 Aug 2016 16:06:07 -0400 Subject: integration_cleanup: Force testcase cleanup to always run During testcase development on the integration side, if namespaces are used or veth ports and an exception is raised. The namespaces and veth ports are not properly cleanup up because the run_finalize does not get executed. This patch wraps the testing block in a try block where a finally will ALWAYS execute the run_finalize thus preventing the possiblity of leftover testing artifacts.
