How would you create an instance of a webdriver the first time the script is called, and then retrieve that same instance the next times? Something like this pseudocode:

from selenium import webdriver

thisScript = FIXME

if thisScript.isRunning():
    driver = thisScript.driver

else:        
    driver = webdriver.Firefox()

driver.get("http://www.example.com")

最良のオプションはサーバー/クライアントシステムをセットアップすることのようです。セレンサーバーを使用してセットアップできると思いますが、私は自分でコーディングすることになりました。次のようになります。

#!/usr/bin/env python
#-*- coding:utf-8 -*-
# This script takes a html file name as argument to start the
# selenium webdriver. It will start a server the first time it's run.
# If called again, it will then check if the server is running
# and restart it if neccessary. This prevents from having to restart
# the browser when running tests from different scripts by facilitating
# the running instance of selenium.

        self.host = host if host != None else "localhost"
        self.port = port if port != None else self.getFreePort()

        self.driver = webdriver.Firefox()

    def getFreePort(self):
        sock = socket.socket()
        sock.bind(('', 0))

        port = sock.getsockname()[1]

        sock.close()

        return port

    def run(self):
        server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        server.bind((self.host, self.port))
