Playwright-录制脚本进行自动化测试

一、简介

公司最近准备用flutter来写web端页面，需要做ui自动化测试，由于flutter的页面元素无法定位，不能用selenium+unittest的方法进行，只能寻求其它的自动化方法，这时发现flutter录制脚本可以录制操作，然后自动生成脚本文件，然后运行脚本文件就可以实现了。

Playwright是微软推出来的一款自动化测试工具

官方：https://playwright.dev/

介绍

Playwright enables fast, reliable and capable automation across all modern browsers.

支持平台&浏览器

 LinuxmacOSWindows
Chromium 89.0.4344.0 ✅ ✅ ✅
WebKit 14.1 ✅ ✅ ✅
Firefox 84.0b9 ✅ ✅ ✅

支持语言

二、安装

第 1 步，安装  playwright-python

　pip install playwright

 第 2 步，安装的浏览器驱动，会将 Chromeium、Firefox、Webkit 浏览器驱动下载到本地

python -m playwright install

安装完成后，可以查看课时使用的命令

python -m playwright help
C:\Users\Administrator>python -m playwright help
Usage: npx playwright [options] [command]

Options:
  -V, --version                          output the version number
  -h, --help                             display help for command

Commands:
  open [options] [url]                   open page in browser specified via -b,
--browser
  codegen [options] [url]                open page and generate code for user ac
tions
  debug <app> [args...]                  run command in debug mode: disable time
out, open inspector
  install [browser...]                   ensure browsers necessary for this vers
ion of Playwright are installed
  install-deps [browser...]              install dependencies necessary to run b
rowsers (will ask for sudo permissions)
  cr [options] [url]                     open page in Chromium
  ff [options] [url]                     open page in Firefox
  wk [options] [url]                     open page in WebKit
  screenshot [options] <url> <filename>  capture a page screenshot
  pdf [options] <url> <filename>         save page as pdf
  show-trace [options] [trace]           Show trace viewer
  help [command]                         display help for command

三、录制脚本

  • python -m playwright codegen 录制脚本
  • –help 帮助文档
  • -o 生成自动化脚本的目录（文件默认生成的地址为你cmd运行命令的地址，也可以在命令中输入需要保存的地址）
  • –target 脚本语言，包含 JS 和 Python，分别对应值为：python 和 javascript
  • -b 指定浏览器驱动

在cmd中执行：

python -m playwright codegen --target python -o test.py -b chromium https://www.baidu.com

命令运行后会自动打开浏览器，同时会打开一个Inspector ，所有的操作都会自动生成脚本显示在Inspector 里面，关闭浏览器这是脚本会自动保存

 

可以查看保存的py文件

 

 1 from playwright.sync_api import Playwright, sync_playwright
 2 
 3 
 4 def run(playwright: Playwright) -> None:
 5     browser = playwright.chromium.launch(headless=False)
 6     context = browser.new_context()
 7 
 8     # Open new page
 9     page = context.new_page()
10 
11     # Go to https://www.baidu.com/
12     page.goto("https://www.baidu.com/")
13 
14     # Click input[name="wd"]
15     page.click("input[name=\"wd\"]")
16 
17     # Fill input[name="wd"]
18     page.fill("input[name=\"wd\"]", "测试")
19 
20     # Press Enter
21     # with page.expect_navigation(url="https://www.baidu.com/s?ie=utf-8&f=8&rsv_bp=1&rsv_idx=1&tn=baidu&wd=%E6%B5%8B%E8%AF%95&fenlei=256&rsv_pq=e29e95d200057ece&rsv_t=6332vNWuKAWk0z%2Be3iFDs%2Fy16SkgQUYh7xVJHgu6DzflmHOv%2F4n2clPFJwY&rqlang=cn&rsv_enter=1&rsv_dl=tb&rsv_sug3=7&rsv_sug1=5&rsv_sug7=100&rsv_sug2=0&rsv_btype=i&prefixsug=%25E6%25B5%258B%25E8%25AF%2595&rsp=5&inputT=868&rsv_sug4=1743&rsv_jmp=fail"):
22     with page.expect_navigation():
23         page.press("input[name=\"wd\"]", "Enter")
24     # assert page.url == "https://www.baidu.com/s?ie=utf-8&f=8&rsv_bp=1&rsv_idx=1&tn=baidu&wd=%E6%B5%8B%E8%AF%95&fenlei=256&rsv_pq=e29e95d200057ece&rsv_t=6332vNWuKAWk0z%2Be3iFDs%2Fy16SkgQUYh7xVJHgu6DzflmHOv%2F4n2clPFJwY&rqlang=cn&rsv_enter=1&rsv_dl=tb&rsv_sug3=7&rsv_sug1=5&rsv_sug7=100&rsv_sug2=0&rsv_btype=i&prefixsug=%25E6%25B5%258B%25E8%25AF%2595&rsp=5&inputT=868&rsv_sug4=1743"
25 
26     # Close page
27     page.close()
28 
29     # ---------------------
30     context.close()
31     browser.close()
32 
33 
34 with sync_playwright() as playwright:
35     run(playwright)

同时还支持同步和异步的操作
