From bedcb3c33d14bd4259c37bcbca8a49d757c8cef4 Mon Sep 17 00:00:00 2001
From: Emma Foley <emma.l.foley@intel.com>
Date: Mon, 20 Nov 2017 15:20:49 +0000
Subject: Clean unit tests in "benchmark.scenarios.lib.test_create_volume.py

* Use mock_object.assert_called_with instead of
    self.assertTrue(mock_object.called)
* Remove an unneeded if clause in CreateVolume
* Add individual tests for each method in CreateVolume
