Selenium Python - Cross-Browser Testing

What will be the output of the following code snippet?

from selenium.webdriver import Firefox
from selenium.webdriver.firefox.options import Options

options = Options()
options.headless = True
browser = Firefox(options=options)
print(browser.capabilities['moz:headless'])
browser.quit()

AKeyError exception

BTrue

CNone

DFalse

Step-by-Step Solution

Solution:

Step 1: Understand headless option effect on capabilities
Setting options.headless = True tells Firefox to run without UI, reflected in capabilities under key 'moz:headless' as True.
Step 2: Check the print statement output
The print statement accesses browser.capabilities['moz:headless'], which will be True because headless mode is enabled.
Final Answer:
True -> Option B
Quick Check:
Headless mode enabled means moz:headless = True [OK]

Quick Trick: Check capabilities key 'moz:headless' for headless status [OK]

Common Mistakes:

Assuming 'moz:headless' key is missing
Expecting False when headless is set True
Confusing capabilities with options
