'WebDriver' object has no attribute 'is_connected' error for successful test

[merrillh]

I recently updated chromededriver to 136 and package requirements (selenium==4.32.0, seleniumbase==4.38.2). I'm using a BaseTestCase to handle setUp and tearDown for multiple tests but I get an error for a test that should pass. The chromedriver opens an instance of Chrome locally and runs through everything correctly. Printing out webdriver.Chrome(options=options) shows that the driver is being created. However, I get AttributeError: 'WebDriver' object has no attribute 'is_connected'
I'm not using CDP Mode and I'm wondering if I have something misconfigured.

Good catch. For now, override the is_connected() method as a workaround:

def is_connected(self, *args, **kwargs): return True 

Full example:

from selenium import webdriver from seleniumbase import BaseCase BaseCase.main(__name__, __file__) class BaseTestCase(BaseCase): def get_new_driver(self, *args, **kwargs): """This method overrides get_new_driver() from BaseCase.""" options = webdriver.ChromeOptions() options.add_argument("--disable-notifications") if self.headless: options.add_argument("--headless=new") options.add_argument("--disable-gpu") options.add_experimental_option( "excludeSwitches", ["enable-automation", "enable-logging"], ) prefs = { "credentials_enable_service": False, "profile.password_manager_enabled": False, } options.add_experimental_option("prefs", prefs) return webdriver.Chrome(options=options) def is_connected(self, *args, **kwargs): return True def test_driver_override(self): self.open("https://seleniumbase.io/demo_page") self.type("#myTextInput", "This is Automated") self.set_value("input#mySlider", "100") self.select_option_by_text("#mySelect", "Set to 100%") self.click("#checkBox1") self.drag_and_drop("img#logo", "div#drop2") self.click('button:contains("Click Me")') self.assert_text("SeleniumBase")

I'll have a real fix in the next release, which may be delayed slightly because I'm at PyCon this week:
https://us.pycon.org/2025/

But the workaround should be fine until then if you're overriding get_new_driver().
