### Question:
TreeModel implements Serializable { public void ergodicTreeInWith(int msg) { Deque<NodeModel<T>> queue = new ArrayDeque<>(); NodeModel<T> rootNode = getRootNode(); queue.add(rootNode); while (!queue.isEmpty()) { rootNode = (NodeModel<T>) queue.poll(); if (mForTreeItem != null) { mForTreeItem.next(msg, rootNode); } LinkedList<NodeModel<T>> childNodes = rootNode.getChildNodes(); if (childNodes.size() > 0) { for (NodeModel<T> item : childNodes) { queue.add(item); } } } } TreeModel(NodeModel<T> rootNode); void addNode(NodeModel<T> start, NodeModel<T>... nodes); boolean removeNode(NodeModel<T> starNode, NodeModel<T> deleteNote); boolean inTree(NodeModel<T> starNode, NodeModel<T> deleteNote); NodeModel<T> getRootNode(); void setRootNode(NodeModel<T> rootNode); ArrayList<NodeModel<T>> getAllLowNodes(NodeModel<T> addNode); ArrayList<NodeModel<T>> getAllPreNodes(NodeModel<T> addNode); LinkedList<NodeModel<T>> getNodeChildNodes(NodeModel<T> node); void ergodicTreeInDeep(int msg); void ergodicTreeInWith(int msg); void addForTreeItem(ForTreeItem<NodeModel<T>> forTreeItem); Object deepClone();  }### Answer:
@Test public void ergodicTreeInWith() throws Exception { }
