Question

所以我有一套黄瓜测试，在BeforeFeatures部分我在同一台服务器上创建了与2个数据库的连接，我已经将池设置为2，所以我可以看到连接4个连接时（2）有2个池的数据库。）

然后在最后我关闭数据库，如下：

var closeDatabase = function(callback) {
    db1.close(function(){
        db2.close(function(){
            console.log("DONE");
            callback();
        });
    });
};

现在调用它，我看到控制台输出和进程关闭，因此应该关闭两个数据库连接。但是如果我看一下mongodb日志：

所以最后虽然2个连接已经结束，但似乎让4个连接中的3个处于活动状态。这就是说，如果我们看看端口，它似乎激活6个端口，即使它只有4个连接。

这是常见的吗？我应该担心还是我做错了什么？这是一个问题的全部原因是因为当我尝试使用连接时，我得到错误：

MongoError: server localhost:27017 sockets closed

所以当我尝试使用连接时，为什么它看似过度分配和轰炸我感到有些困惑。

Answer 1

所以错误是正确的，它正在关闭连接然后使用它们，因为它们的方式控制台输出发生在Windows上，它们并不总是100％正确的顺序。事实证明，黄瓜在一个地区默默地轰炸，并在这里发挥作用。

Mongodb连接未在nodejs测试中关闭
