playwright使用

playwright是一款功能强大的自动化测试工具，它支持异步操作，内置浏览器驱动，同时也支持移动端测试。使用playwright可以通过以下步骤：

1. 首先，你需要安装playwright库。可以使用以下命令进行安装：

   pip install --upgrade pip
   pip install playwright
   playwright install

2. 导入所需的模块和方法：

   from playwright.sync_api import sync_playwright

3. 创建一个run函数，并在其中编写你的自动化测试代码：

   def run(playwright):
       # 创建浏览器实例
       browser = playwright.chromium.launch(headless=False)
       # 创建上下文
       context = browser.new_context()
       # 创建页面
       page = context.new_page()
       # 进行页面操作，比如打开网址、点击按钮等
       page.goto("https://www.example.com")
       # 进行其他测试操作...

   # 使用with语句调用run函数
   with sync_playwright() as playwright:
       run(playwright)

4. 运行你的测试脚本。
