压测工具k6

k6是什么？

js脚本写用例的压测工具，简单、快速、报告详细

 

使用方法

1. 安装（windows下)

choco install k6

2. 写测试脚本

import {check} from 'k6';
import http from 'k6/http';

export const options = {
    vus:10,
    duration:'1m',
    insecureSkipTLSVerify:true
};

export default ()=>{
    const url = 'http://localhost:7257/weather';
    const payload = JSON.stringify({fullname:"nick"});
    const params = {
        headers:{
            'Content-Type':'application/json'
        }
    }
    
    const res = http.get(url);
    
    check(res,{
        'is status 400':(r)=>r.status === 400,
    });
}

3.脚本所在目录 打开命令行，并执行

k6 run .\stresstest.js

4.报告结果

     /\  /  \     |  |/  /   /  /

 5. 附被测代码

[HttpGet("weather")]
   [BetterServiceFilter<LoggingFilter>(Order = 1)] 
    public IEnumerable<int> Index()
    {
        using (var _ = _logger.TimedOperation("begin {-1}", nameof(Index)))
        {
            return Enumerable.Range(1, 5);
        }
    }
