### Question:
HibernateMenuDAO extends HibernatePersistentObjectDAO<Menu> implements MenuDAO { @Override public List<Menu> findByName(String name) { return findByName(null, name, true); } protected  HibernateMenuDAO(); UserDAO getUserDAO(); void setUserDAO(UserDAO userDAO); @Override boolean store(Menu menu); @Override @SuppressWarnings("rawtypes") List<Menu> findByUserId(long userId); @Override List<Menu> findByUserId(long userId, long parentId); @SuppressWarnings("rawtypes") List<Menu> findByUserId(long userId, long parentId, Integer type); @Override List<Menu> findChildren(long parentId, Integer max); @SuppressWarnings("rawtypes") @Override List<Menu> findChildren(long parentId, long userId); List<Menu> findByParentId(long parentId); @Override @SuppressWarnings("rawtypes") boolean isWriteEnable(long menuId, long userId); @Override @SuppressWarnings("rawtypes") boolean isReadEnable(long menuId, long userId); @Override String findNameById(long menuId); @Override List<Long> findMenuIdByUserId(long userId); int isMenuWriteable(long menuId, long userId); @Override boolean hasWriteAccess(Menu menu, long userId); @Override List<Menu> findByGroupId(long groupId); @SuppressWarnings("rawtypes") List<Long> findIdByUserId(long userId, long parentId, Integer type); @Override List<Menu> findByName(String name); @Override List<Menu> findByName(Menu parent, String name, boolean caseSensitive); @Override String computePathExtended(long menuId); @Override List<Menu> findByNameAndParentId(String name, long parentId); @Override List<Menu> findParents(long menuId); @Override void restore(long menuId, boolean parents); @Override List<Long> findMenuIdByUserIdAndPermission(long userId, Permission permission); @Override void deleteAll(Collection<Menu> menus); @Override boolean delete(long menuId, int code); @Override boolean applyRightToTree(long id); @SuppressWarnings("rawtypes") @Override List<Long> findIdByUserId(long userId, long parentId);  }### Answer:
@Test public void testFindByName() { List<Menu> menus = (List<Menu>) dao.findByName(null, "abc", true); Assert.assertNotNull(menus); Assert.assertEquals(0, menus.size()); menus = (List<Menu>) dao.findByName(null, "abc", false); Assert.assertNotNull(menus); Assert.assertEquals(1, menus.size()); menus = dao.findByName("xxxxx"); Assert.assertNotNull(menus); Assert.assertTrue(menus.isEmpty()); }
