代码都在top/xianghua/mydb/server/im/BPlusTreeTest.java中

运行如下单元测试，得到测试结果

public class BPlusTreeTest {@Testpublic void testTreeSingle() throws Exception {TransactionManager tm = new MockTransactionManager();DataManager dm = DataManager.create("E:\\temp\\TestTreeSingle", PageCache.PAGE_SIZE*10, tm);long root = BPlusTree.create(dm);BPlusTree tree = BPlusTree.load(root, dm);int lim = 10000;for(int i = lim-1; i >= 0; i --) {tree.insert(i, i);}tree.insert(10000, 10000);for(int i = 0; i < lim; i ++) {List<Long> uids = tree.search(i);assert uids.size() == 1;assert uids.get(0) == i;}assert new File("/tmp/TestTreeSingle.db").delete();assert new File("/tmp/TestTreeSingle.log").delete();}
}
