Browser options and capabilities in Selenium Python - Test Execution Trace

Test Overview

This test opens a Chrome browser with specific options to disable notifications and run in headless mode. It verifies the browser title to confirm the page loaded correctly.

Test Code - unittest

Selenium Python

from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.common.by import By
import unittest

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

    def test_google_title(self):
        self.driver.get('https://www.google.com')
        title = self.driver.title
        self.assertEqual(title, 'Google')

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

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