### Question:
NodeService { public void create(String cluster, String path, String data, String creator) throws ShepherException { nodeBiz.create(cluster, path, data); long zkCreationTime = nodeDAO.getCreationTime(cluster, path); snapshotBiz.create(cluster, path, data, creator, Action.ADD, zkCreationTime, ReviewStatus.ACCEPTED, ReviewUtil.NEW_CREATE_VERSION, ReviewUtil.DEFAULT_REVIEWER); logger.info("Create node, cluster={}, path={}, operator={}", cluster, path, creator); }  List<String> getChildren(String cluster, String path); String getData(String cluster, String path); Stat getStat(String cluster, String path); Stat getStat(String cluster, String path, boolean returnNullIfPathNotExists); void create(String cluster, String path, String data, String creator); void create(String cluster, String path, String data, String creator, boolean createParents); void createEphemeral(String cluster, String path, String data, String creator); void updateWithPermission(String cluster, String path, String data, String creator); void update(String cluster, String path, String data, String creator); void delete(String cluster, String path, String creator);  }### Answer:
@Test public void testCreate() throws Exception { nodeService.create("local_test", "/test", "data", "creator"); }
