自己上手寫性能測試工具(二)

上周教大家如何通過Python實現性能測試工具,最後留了一下問題,今天我們繼續來實現命令行工具。

依賴庫

requests==2.22.0
gevent==20.9.0
numpy==1.19.2
click==7.1.2

click 庫

今天的主角是click庫。

中文文檔://www.osgeo.cn/click/index.html

第一個例子(hello.py):

import click

@click.command()
@click.argument('name')
@click.option('-c', default=1, help='number of greetings')
def hello(name, c):
    for x in range(c):
        click.echo('Hello %s!' % name)


if __name__ == "__main__":
    hello()

查看幫助:

> python3 hello.py --help
Usage: hello.py [OPTIONS] NAME

Options:
  -c INTEGER  number of greetings
  --help      Show this message and exit.

使用:

> python3 hello.py 蟲師 -c 3
Hello 蟲師!
Hello 蟲師!
Hello 蟲師!

現在已經掌握了click 的基本用法。

實現命令行性能測試工具

接下來,將click引入到kb.py性能測試腳本中。

from __future__ import print_function
import gevent
from gevent import monkey
monkey.patch_all()
import time
import click
import requests
from numpy import mean


class statistical:
    pass_number = 0
    fail_number = 0
    run_time_list = []


def running(url, numbers):
    for _ in range(numbers):
        start_time = time.time()
        r = requests.get(url)
        if r.status_code == 200:
            statistical.pass_number = statistical.pass_number + 1
            print(".", end="")
        else:
            statistical.fail_number = statistical.fail_number + 1
            print("F", end="")

        end_time = time.time()
        run_time = round(end_time - start_time, 4)
        statistical.run_time_list.append(run_time)


@click.command()
@click.argument('url')
@click.option('-u', default=1, help='運行用戶的數量,默認 1', type=int)
@click.option('-q', default=1, help='單個用戶請求數,默認 1', type=int)
def main(url, u, q):
    print("請求URL: {url}".format(url=url))
    print("用戶數:{},循環次數: {}".format(u, q))
    print("============== Running ===================")

    jobs = [gevent.spawn(running, url, q) for _url in range(u)]
    gevent.wait(jobs)

    print("\n============== Results ===================")
    print("最大:       {} s".format(str(max(statistical.run_time_list))))
    print("最小:       {} s".format(str(min(statistical.run_time_list))))
    print("平均:       {} s".format(str(round(mean(statistical.run_time_list), 4))))
    print("請求成功", statistical.pass_number)
    print("請求失敗", statistical.fail_number)
    print("============== end ===================")


if __name__ == "__main__":
    main()

查看幫助:


python3 kb.py --help
Usage: kb.py [OPTIONS] URL

Options:
  -u INTEGER  運行用戶的數量,默認 1
  -q INTEGER  單個用戶請求數,默認 1
  --help      Show this message and exit.

使用方法:

> python3 kb.py //wwww.baidu.com -u 10 -q 10

請求URL: //wwww.baidu.com
用戶數:10,循環次數: 10
============== Running ===================
....................................................................................................
============== Results ===================
最大:       0.955 s
最小:       0.2573 s
平均:       0.4585 s
請求成功 100
請求失敗 0
============== end ===================
