用Playwright写一个基于python的web测试脚本

好的，我明白您的要求。以下是用Playwright编写基于Python的Web测试脚本的示例代码：

from playwright.sync_api import Playwright, sync_playwright

def run(playwright: Playwright) -> None:
    browser = playwright.chromium.launch()
    page = browser.new_page()
    page.goto("https://www.example.com")
    assert page.title() == "Example Domain"
    browser.close()

with sync_playwright() as playwright:
    run(playwright)

这个脚本实现了以下操作：

1. 使用Playwright库加载Chromium浏览器。
2. 创建一个新的浏览器页面。
3. 访问 https://www.example.com 网站。
4. 验证页面标题是否为 "Example Domain"。
5. 关闭浏览器。

希望这个示例代码能满足您的需求。
