Subject: Remove use of nose attrib plugin and most unittest
X-Git-Tag: 2014.1~674
X-Git-Url: https://review.fuel-infra.org/gitweb?a=commitdiff_plain;h=2c4eea5500691a7cbc84fc0273a5a79bc03fe78d;p=openstack-build%2Fheat-build.git

Remove use of nose attrib plugin and most unittest

Some simple cases that do not use mox still use unittest directly.
Replacing unittest.TestCase with HeatTestCase has the added benefit of
capturing all logging for reporting during failure.
