playwright是由微軟開發(fā)的Web UI自動(dòng)化測(cè)試工具,本文主要介紹了Python中Playwright模塊進(jìn)行自動(dòng)化測(cè)試的實(shí)現(xiàn),具有一定的參考價(jià)值,感興趣的可以了解一下

它支持主流的瀏覽器，包含：Chrome、Firefox、Safari、Microsoft Edge 等，同時(shí)支持以無(wú)頭模式、有頭模式運(yùn)行，并提供了同步、異步的 API，可以結(jié)合 Pytest 測(cè)試框架使用，并且支持瀏覽器端的自動(dòng)化腳本錄制。

Playwright提供的自動(dòng)化技術(shù)是綠色的、功能強(qiáng)大、可靠且快速，支持Linux、Mac以及Windows操作系統(tǒng)。

官網(wǎng)：https://playwright.dev/

從官網(wǎng)的解釋，官方給Playwright定位是一款真正意義上的Web端到端測(cè)試工具。

安裝步驟

第 1 步，安裝 playwright-python 依賴庫(kù) (需要注意的是，playwright庫(kù)需要依賴Python3.7+以上)

pip install -i https://mirrors.aliyun.com/pypi/simple/ --upgrade Playwright

第 2 步，安裝主流的瀏覽器驅(qū)動(dòng)

playwright install

如果想查看Playwright支持的功能，可以直接在命令行輸入：playwright -h

使用Playwright可以無(wú)需寫代碼，只需手動(dòng)操作瀏覽器，它會(huì)錄制我們的操作，然后自動(dòng)生成代碼腳本。

錄制腳本

1. 查看錄制命令說(shuō)明 playwright codegen -h

Usage: playwright codegen [options] [url]

open page and generate code for user actions

Options:
  -o, --output <file name>             saves the generated script to a file
  --target <language>                  language to generate, one of javascript, playwright-test, python, python-async,
                                       python-pytest, csharp, csharp-mstest, csharp-nunit, java (default: "python")
  --save-trace <filename>              record a trace for the session and save it to a file
  --test-id-attribute <attributeName>  use the specified attribute to generate data test ID selectors
  -b, --browser <browserType>          browser to use, one of cr, chromium, ff, firefox, wk, webkit (default:
                                       "chromium")
  --block-service-workers              block service workers
  --channel <channel>                  Chromium distribution channel, "chrome", "chrome-beta", "msedge-dev", etc
  --color-scheme <scheme>              emulate preferred color scheme, "light" or "dark"
  --device <deviceName>                emulate device, for example  "iPhone 11"
  --geolocation <coordinates>          specify geolocation coordinates, for example "37.819722,-122.478611"
  --ignore-https-errors                ignore https errors
  --load-storage <filename>            load context storage state from the file, previously saved with --save-storage
  --lang <language>                    specify language / locale, for example "en-GB"
  --proxy-server <proxy>               specify proxy server, for example "http://myproxy:3128" or
                                       "socks5://myproxy:8080"
  --proxy-bypass <bypass>              comma-separated domains to bypass proxy, for example
                                       ".com,chromium.org,.domain.com"
  --save-har <filename>                save HAR file with all network activity at the end
  --save-har-glob <glob pattern>       filter entries in the HAR by matching url against this glob pattern
  --save-storage <filename>            save context storage state at the end, for later use with --load-storage
  --timezone <time zone>               time zone to emulate, for example "Europe/Rome"
  --timeout <timeout>                  timeout for Playwright actions in milliseconds, no timeout by default
  --user-agent <ua string>             specify user agent string
  --viewport-size <size>               specify browser viewport size in pixels, for example "1280, 720"
  -h, --help                           display help for command

Examples:

  $ codegen
  $ codegen --target=python
  $ codegen -b webkit https://example.com

比如，我要在baidu.com搜索，用chromium驅(qū)動(dòng)，將結(jié)果保存為test.py的python文件。文檔默認(rèn)保存到 C:\Users\user\下面

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