【K6】使用InfluxDB和Grafana图形化展示k6压测工具的测试数据【测试成功】

sudo dnf install https://dl.k6.io/rpm/repo.rpm
sudo dnf install k6

 import http from "k6/http";
 import {group, check} from "k6";
 
 export let options = {
   stages: [
     {duration: '30s', target: 5},
     {duration: '30s', target: 20},
     {duration: '30s', target: 50},
     {duration: '60s', target: 100},
   ]
 };
 
 export default function () {
 
   group('html page', function () {
     const res = http.get("http://www.xxx.com/about");
     check(res, {
       "status was 200": (r) => r.status === 200
     });
   });
 
 };


这个脚本是用于使用 k6 对网站进行负载测试的，k6 是一个流行的开源负载测试工具。


以下是脚本的功能：


1. 它从 k6 导入必要的模块：`http` 用于发出 HTTP 请求，`check` 用于验证响应。


2. 它在 `options` 对象中定义了测试的负载配置。测试将从 30 秒的 5 个虚拟用户开始，然后在接下来的 30 秒内增加到 20 个用户，再在接下来的 30 秒内增加到 50 个用户，最后在 60 秒内增加到 100 个用户。


3. `default` 函数是测试的入口点。它定义了每个虚拟用户在测试期间将执行的操作。


4. 在 `default` 函数内部，它将操作分组在 'html page' 下。这对于组织测试结果非常有用。


5. 它向网站的 "/about" 页面发送 GET 请求（将 "www.xxx.com" 替换为你要测试的实际网站）。


6. 它检查响应状态码以确保它是 200（HTTP OK）。如果状态码不是 200，检查将失败，并在测试结果中报告失败。
