Question

我正在尝试在 Jenkins CI 中运行 python selenium 测试。 python 测试在本地运行良好，但在服务器上运行不正常。当我在服务器上运行时出现此错误

我不知道这是什么意思。如果您需要更多信息，请告诉我。此外，Jenkins CI 在外部服务器上运行，这意味着测试必须是无头的。

错误是：

selenium.common.exceptions.WebDriverException: Message: unknown error: net::ERR_CONNECTION_REFUSED

意思是chrome无法连接到网站。这可能是因为服务器无法连接到互联网

您可以通过关闭网络并连接到某个网站来在 locat 中重新创建此异常

SO 验证 jenkins CI 是否可以访问您正在测试的网站
