本文介绍了一种方法，用于检查远程端口的连接状态，确定其是否可以创建新的会话。通过Python的selenium库中webdriver.common.utils模块的is_url_connectable函数，可以判断给定端口的当前状态是否允许建立新连接。然而，即使返回true，也不能完全保证New Session命令一定成功。
Status
Java:// TODO
Python:selenium.webdriver.common.utils.is_url_connectable(port)
Description
Returns information about whether a remote end is in a state in which it can create new sessions and can additionally include arbitrary meta information that is specific to the implementation.
The readiness state is represented by the ready property of the body, which is false if an attempt to create a session at the current time would fail. However, the value true does not guarantee that a New Session command will succeed.
Implementations may optionally include additional meta information as part of the body, but the top-level properties ready and message are reserved and must not be overwritten
