难以测试或测试无效化的场景

#buf

假设

1. 接口是http://xxx.xxx/update_all_user, 没有其他参数
2. 业务需求是我有一波users通过http接口取自第三方系统，想存到本项目的数据库里。根据userId这个主键来判断，如果数据库user表里有一致的主键，就把数据表这条记录中其他的字段更新成user对应的属性，否则就把user作为一条新的记录插入数据表
3. 本项目使用了一个我不熟悉的orm库叫 internal-orm, internal-orm是我们公司自己写的内部使用的库

实操

1. 现在internal-orm提供了3个api，分别是 writeAll() persistAll() 和 saveAll()，我不清楚这3个api的语义，我填写配置文件连接了数据库，并且尝试性的选择了writeAll来实现业务需求。
