Selenium Python - Cross-Browser Testing

You wrote this code to run Chrome in headless mode but the browser window still appears. What is the likely mistake?

from selenium import webdriver
options = webdriver.ChromeOptions()
driver = webdriver.Chrome(options=options)
options.add_argument('--headless')
driver.get('https://example.com')

AHeadless mode is not supported on Chrome

BThe headless argument was added after creating the driver, so it was ignored

CYou must call driver.set_headless(True) after creating the driver

DYou forgot to call driver.quit() to close the window

Step-by-Step Solution

Solution:

Step 1: Check order of setting options
The headless argument must be added to options before creating the driver instance.
Step 2: Identify mistake in code
Here, options.add_argument('--headless') is called after driver creation, so the driver does not run headless.
Final Answer:
The headless argument was added after creating the driver, so it was ignored -> Option B
Quick Check:
Add headless argument before driver creation [OK]

Quick Trick: Add headless option before creating driver instance [OK]

Common Mistakes:

Adding headless argument after driver creation
Calling non-existent set_headless method
Assuming headless unsupported on Chrome
