背景： 我在我的 azure pipleine 中使用上面的 docker 映像作为容器来运行 java selenium 测试用例。

错误：

面临的问题：

但是当我从我的机器或其他 Windows 服务器运行时，该 href 元素就会启动。我也增加了超时时间，但它不起作用。当我拍摄快照时，我发现特定元素根本没有加载。**

Tested multiple way but failing. Any idea upon this**

Answer 1

我认为这里的问题不在docker中，因为如果它运行没有错误，则意味着它运行所有命令并正确安装所有内容 在这里您需要添加更多等待此元素尝试使用 Explicate 等待此特定元素 60 SC，以防该元素存在并且您可以在本地运行相同的测试..尝试使用此 xpath //a[contains (text(),'ExcelDataListOverall')]"，也尝试添加另一个超时等待驱动程序。manage().timeouts().pageLoadTimeout(Duration.of Seconds(60));

另外，请确保浏览器是 hedless>true
