Pairwise是L. L. Thurstone(29 May1887 – 30 September 1955)在1927年首先提出来的。他是美国的一位心理统计学家。Pairwise也正是基于数学统计和对传统的正交分析法进行优化后得到的产物。

selenium的挑战者 - playwright简析

搭建环境

• 安装库 pip install playwright

• 安装浏览器 python -m playwright install

 

from playwright.sync_api import sync_playwright
import time

with sync_playwright() as p:
    iphone_11 = p.devices['iPhone 11 Pro']
    browser = p.webkit.launch(headless=False)
    context = browser.new_context(
        **iphone_11,
        locale='en-US',
        geolocation={ 'longitude': 12.492507, 'latitude': 41.889938 },
        permissions=['geolocation']
    )
    page = context.new_page()
    page.goto('https://maps.google.com')
    page.click('text="Your location"')
    time.sleep(5)
    page.screenshot(path='colosseum-iphone.png')
    browser.close()

简单来说以下几方面playwright有点优势:

执行速度 - playwright运行时可以通过设置Headless后台直接运行,不用展示过程

Actionability - playwright不需要在代码中做等待判断,例如等待下一个页面出现时再点击某个按钮,这在playwright中会自动判断. 而selenium在代码中几乎每个点击都需要手动加入判断,甚至加入延迟时间,延迟时间加多了的话,极大影响执行效率.

Selectors - 在playwright中可以直接通过页面文本字符来选择对应元素.

Multi-tab & frames

软件测试用例设计之Pairwise算法

from allpairspy import AllPairs

parameters = [
    ["南","北","沈","兰","成","济","广","参","证","后","装","海","空"],
    ['6位', '7位', '8位'],
]

print("PAIRWISE:")
for i, pairs in enumerate(AllPairs(parameters)):
    print("{:2d}: {}".format(i, pairs))
