question: public void test_prefixNamespaceOverride ( ) { final IIndexManager indexManager = null ; final Properties properties = new Properties ( ) ; final String namespace = "foo.baz" ; final String globalName = "bigdata.bar" ; final String defaultValue = "goo" ; final String overrideName = Configuration . getOverrideProperty ( namespace , globalName ) ; final String overrideValue = "boo" ; assertEquals ( defaultValue , Configuration . getProperty ( indexManager , properties , namespace , globalName , defaultValue ) ) ; properties . setProperty ( overrideName , overrideValue ) ; assertEquals ( overrideValue , Configuration . getProperty ( indexManager , properties , namespace , globalName , defaultValue ) ) ; }
target:  Unit test where the property override is applied at the parent level in the namespace ("foo" vs "foo.baz").
