[Solved] Consider this code snippet: from selenium import webdriver from selenium.webdriver.common.... | Selenium Python

Selenium Python - Selenium Grid

Consider this code snippet:

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

remote_url = 'http://localhost:4444/wd/hub'
driver = webdriver.Remote(command_executor=remote_url, desired_capabilities=DesiredCapabilities.FIREFOX)
print(driver.session_id)
driver.quit()

What will happen if no Firefox node is registered to the Grid?

ASessionNotCreatedException error

BPrints a valid session ID

CPrints None

DTimeout and then prints session ID

Step-by-Step Solution

Solution:

Step 1: Understand node availability impact
If no Firefox node is available, Grid cannot create a session for Firefox.
Step 2: Identify error raised
Selenium raises SessionNotCreatedException when requested browser node is missing.
Final Answer:
SessionNotCreatedException error -> Option A
Quick Check:
No node for browser = SessionNotCreatedException [OK]

Quick Trick: No matching node causes SessionNotCreatedException [OK]

Common Mistakes:

Expecting session ID even if node missing
Assuming None is returned
Thinking timeout prints session ID
