Allow webdriver to attach to a running browser #18 https://github.com/seleniumhq/selenium-google-code-issue-archive/issues/18

You may be interested in what I have implemented as PersistentWebdriver class that allows to attach to a running session:

I got a solution in python, I modified the webdriver class bassed on PersistenBrowser class that I found.

https://github.com/axelPalmerin/personal/commit/fabddb38a39f378aa113b0cb8d33391d5f91dca5

replace the webdriver module /usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py

Ej. to use:

from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

runDriver = sys.argv[1]
sessionId = sys.argv[2]

def setBrowser():
    if eval(runDriver):
        webdriver = w.Remote(command_executor='http://localhost:4444/wd/hub',
                     desired_capabilities=DesiredCapabilities.CHROME,
                     )
    else:
        webdriver = w.Remote(command_executor='http://localhost:4444/wd/hub',
                             desired_capabilities=DesiredCapabilities.CHROME,
                             session_id=sessionId)

    url = webdriver.command_executor._url
    session_id = webdriver.session_id
    print url
    print session_id
    return webdriver

This snippet successfully allows to reuse existing browser instance yet avoiding raising the duplicate browser. Found at Tarun Lalwani’s blog.

from selenium import webdriver
from selenium.webdriver.remote.webdriver import WebDriver

# executor_url = driver.command_executor._url
# session_id = driver.session_id

def attach_to_session(executor_url, session_id):
    original_execute = WebDriver.execute
    def new_command_execute(self, command, params=None):
        if command == "newSession":
            # Mock the response
            return {'success': 0, 'value': None, 'sessionId': session_id}
        else:
            return original_execute(self, command, params)
    # Patch the function before creating the driver object
    WebDriver.execute = new_command_execute
    driver = webdriver.Remote(command_executor=executor_url, desired_capabilities={})
    driver.session_id = session_id
    # Replace the patched function with original function
    WebDriver.execute = original_execute
    return driver

bro = attach_to_session('http://127.0.0.1:64092', '8de24f3bfbec01ba0d82a7946df1d1c3')
bro.get('http://ya.ru/')
