Selenium Python - Selenium Grid

What is wrong with this Selenium Grid test setup code?

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

remote_url = 'http://localhost:4444/wd/hub'
capabilities = DesiredCapabilities.CHROME
capabilities['browserName'] = 'firefox'
driver = webdriver.Remote(command_executor=remote_url, desired_capabilities=capabilities)
driver.quit()

AModifying DesiredCapabilities.CHROME directly causes unexpected behavior

Bcommand_executor URL is missing port

Cdesired_capabilities argument is deprecated

Ddriver.quit() is missing

Step-by-Step Solution

Solution:

Step 1: Analyze capabilities modification
DesiredCapabilities.CHROME is a shared constant; modifying it changes global state.
Step 2: Identify correct practice
Should copy capabilities before modifying to avoid side effects.
Final Answer:
Modifying DesiredCapabilities.CHROME directly causes unexpected behavior -> Option A
Quick Check:
Do not modify shared DesiredCapabilities directly [OK]

Quick Trick: Copy DesiredCapabilities before changes [OK]

Common Mistakes:

Modifying shared constants
Ignoring port in URL
Thinking quit() is missing
