1、Playwright先容
Playwright是一个强盛的Python库，仅用一个API即可自动实验Chromium、Firefox、WebKit等主流欣赏器自动化操作，并同时支持以无头模式、有头模式运行。
Playwright提供的自动化技能是绿色的、功能强盛、可靠且快速，支持Linux、Mac以及Windows操作系统。
ps:博主从前都是用selenium来做ui自动化测试的, 摆设的时间，还得额外安装一个当地欣赏器，大概去制作一个绿色免安装版的欣赏器（mac、linux还不知道怎么制作）非常的不喜欢。Playwright可以制止这种题目，Playwright安装后，直接是打开欣赏器引擎Chromium、Firefox、WebKit举行驱动操作，绿色且快速。
二、安装
安装playwright库
pip install playwright安装欣赏器驱动文件（安装过程稍微有点慢）
python -m playwright install

options寄义：-o：将录制的脚本生存到一个文件--target：规定天生脚本的语言，有JS和Python两种，默以为Python-b：指定欣赏器驱动我们可以实验一行下令打开欣赏器录制操作并天生脚本，比方：
python -m playwright codegen --target python -o 'demo.py' -b chromium https://www.baidu.com录制关闭后，自动天生demo.py脚本，实验demo.py可以回放。（ps：滚动操作无法录制到，得本身修改代码，添加滚动操作）
