GlobalConfigurationFixture uses unit-tests.conf to determine default and module specific logging levels. Logging will gracefully default to INFO if unit-tests.conf is not found. See unit-tests.conf.sample for a sample configuration file. refs: #1375, #1267 Change-Id: Ib0c4eb4149748e6658f94ef1afa23ddd3072c0fa
