/**
 * 
 * HOW-TO: It's not simply to run this test, as we need differents in nodes UUIDs in data container.
 * 
 * Testing with source distribution. Run test once (like 'mvn clean test') its create repository and
 * register node types. Change source file MultiDbJDBCConnection.java in FIND_NODES_BY_PARENTID
 * variable use " order by I.ID DESC" instead " order by I.ID ". Be careful to revert changes back
 * after test. And run the repository software again on existed and initialized database (like 'mvn
 * test'). On the second phase you'll see repository startup printout with messages like: '>>> Node
 * types registration cycle X started' '<<< Node types registration cycle X finished' where X is
 * cycle number of node types registration. More one cycle can be. It's depends on nodetypes count
 * referenced one-by-one with forward declaration of dependent type.
 * 
 * Another way to perform test it's change order of nodes returned by data container on
 * getChildNodesData(). This can be done by direct change of UUIDs in the data storage (database).
