在配置Selenium环境中遇到启动时driver.get()报HTTP/1.1403Forbidden错误，通过添加ChromeOptions参数`--remote-allow-origins=*`解决。此外，文章提到了在浏览器中使用F12开发者工具选取元素的方法，以及检查XPath唯一性的技巧。对于hover元素并选择下拉框中的选项，是自动化测试中常见的挑战。

解决：创建driver添加option选项

ChromeOptions option = new ChromeOptions();
option.addArguments("--remote-allow-origins=*");

WebDriver driver=new ChromeDriver(option);

浏览器，获取元素，F12打开开发者工具，点击elements相应元素右键-copy- 有几种方式：比如xpath。

检查路径是否唯一的方法：F12之后，ctrl+F，在输入框粘贴路径，如果出现1 of 1字样，则说明查找元素唯一。

问题：hover到某一个元素，出现下拉框，如何选中其中一个选项（百度首页右上方就有类似操作，登陆后，退出）
