Chrome configuration in Selenium Python - Test Execution Trace

Test Overview

This test opens Chrome with a custom configuration to disable notifications and verifies the browser starts with these settings applied.

Test Code - unittest

Selenium Python

from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.chrome.options import Options
import unittest

class TestChromeConfig(unittest.TestCase):
    def setUp(self):
        chrome_options = Options()
        chrome_options.add_argument('--disable-notifications')
        self.driver = webdriver.Chrome(service=Service(), options=chrome_options)

    def test_chrome_starts_with_disabled_notifications(self):
        self.driver.get('https://www.example.com')
        title = self.driver.title
        self.assertIn('Example Domain', title)

    def tearDown(self):
        self.driver.quit()

if __name__ == '__main__':
    unittest.main()

Execution Trace - 5 Steps

Step	Action	System State	Assertion	Result
1	Test starts and ChromeOptions is configured to disable notifications	ChromeOptions object created with '--disable-notifications' argument	-	PASS
2	Chrome browser opens with the configured options	Chrome browser window opens without notification popups	-	PASS
3	Browser navigates to 'https://www.example.com'	Example Domain page loads in browser	-	PASS
4	Test checks if page title contains 'Example Domain'	Page title is 'Example Domain'	assertIn('Example Domain', title)	PASS
5	Test ends and browser closes	Chrome browser window closes	-	PASS

Failure Scenario

Failing Condition: Chrome fails to start with the '--disable-notifications' option or page title does not match

Execution Trace Quiz - 3 Questions

What does the '--disable-notifications' argument do in ChromeOptions?

A Enables notifications for all websites

B Disables JavaScript on the page

C Prevents Chrome from showing notification popups

D Runs Chrome in headless mode

Key Result

Always configure browser options explicitly to control browser behavior during tests, such as disabling notifications to avoid unexpected popups that can interfere with test execution.
