JMeter

JMeter 是目前最为流行的开源性能测试工具，JMeter 本身提供的基于插件的机制允许第三方实现标准 JMeter 所不支持的协议，而 WebSocket 的一个比较好的实现是 WebSocketSampler 。利用此插件，能完成基于 WebSocket 协议的基本性能测试。

安装

下载地址：https://jmeter.apache.org/download_jmeter.cgi

Windows直接下载二进制文件即可

将下载的文件复制/移动到本地目录下。我这里是直接复制到D盘，D:\apache-jmeter-5.4.1

安装Websocket插件包

下载地址：https://bitbucket.org/pjtr/jmeter-websocket-samplers/downloads/

将下载的文件复制/移动到D:\apache-jmeter-5.4.1\lib\ext目录下

启动Jmeter

进入可执行目录D:\apache-jmeter-5.4.1\bin查找批处理文件jmeter.bat

先添加线程组Tinywan Thread Group，再点击添加sampler，就可以看到websocket信息

以上截图表示插件安装成功。

编写测试计划

这里按照之前编写教程填写相关参数即可

var ws = new WebSocket("ws://127.0.0.1:8783");

开源技术小栈测试计划.jmx

1. 连接

选择协议ws/wss，输入ip、端口、路径、请求参数（没有参数可不填）

2.0 加入群聊

JMeter

let $_content = {
  "event": "join",
  "mode": 2,
  "group_id": 100,
  "from_user_id": "10086",
  "from_username": "阿克苏",
  "to_user_id": "10000",
  "content": "加入会话",
};
console.log(JSON.stringify($_content))

JSON.stringify() 方法将一个 JavaScript 对象或值转换为 JSON 字符串。

解析以上转换为JSON字符串

{"event":"join","mode":2,"group_id":100,"from_user_id":"10086","from_username":"阿克苏","to_user_id":"10000","content":"加入会话"}

3.0 说话

需要发送的请求内容

let content = {
      "event": "speak",
      "mode": 2,
      "group_id": 100,
      "from_user_id": "10086",
      "from_username": "阿克苏",
      "to_user_id": "10000",
      "content": "WebSocket教程：消息持久化的实现与应用",
   }
console.log(JSON.stringify(content))

JSON.stringify() 方法将一个 JavaScript 对象或值转换为 JSON 字符串。

解析以上转换为JSON字符串

{"event":"speak","mode":2,"group_id":100,"from_user_id":"10086","from_username":"阿克苏","to_user_id":"10000","content":"WebSocket教程：消息持久化的实现与应用"}

4. 心跳

创建循环控制器

添加 WebSocket Sampler

请求内容

{"event":"ping","content":"ping heartbeat"}

5. 添加查看结果树

上图就是执行结果的查看树，可以在右边的窗口中看到取样器结果、请求、响应数据，其中，请求是客户端向服务器发送的请求，响应数据是服务器接收请求后返回的结果，可以选择不同的结果查看方式，有json、html、xpath等等。

6. 添加聚合报告

运行JMeter

1.0 连接

请求数据

响应数据

2.0 说话

请求数据

响应数据

聚合报告看性能

Samples：样本总数量，等于线程总数 * 循环次数。
Average：请求处理的平均时间(毫秒ms)，是压力测试的主要指标之一。
Median：请求处理的中值时间(毫秒ms)，样本数量中有一半的处理时间在这个值之上，有一半的处理时间在这个值之下。
90%Line，95%Line，99%Line：样本中百分之多少的处理时间都在这个值之下，是压力测试的主要指标之一。
Min：耗时最少的请求时间。
Max：耗时最多的请求时间。
Error%：错误率。
Throughput：吞吐量，服务器每秒处理的请求数。
KB/sec：服务器每秒钟请求的字节数。
