Cookie management in Selenium Python - Test Execution Trace

Test Overview

This test adds a cookie to the browser, verifies it exists, deletes it, and confirms it is removed.

Test Code - Selenium

Selenium Python

from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.common.by import By
import time

# Setup WebDriver
service = Service()
driver = webdriver.Chrome(service=service)

try:
    # Open a simple page
    driver.get('https://www.example.com')

    # Add a cookie
    cookie = {'name': 'testcookie', 'value': 'cookievalue123'}
    driver.add_cookie(cookie)

    # Verify cookie is added
    cookies = driver.get_cookies()
    assert any(c['name'] == 'testcookie' and c['value'] == 'cookievalue123' for c in cookies), 'Cookie not found after adding'

    # Delete the cookie
    driver.delete_cookie('testcookie')

    # Verify cookie is deleted
    cookies_after_delete = driver.get_cookies()
    assert all(c['name'] != 'testcookie' for c in cookies_after_delete), 'Cookie still present after deletion'

finally:
    driver.quit()

Execution Trace - 7 Steps

Step	Action	System State	Assertion	Result
1	Test starts and WebDriver Chrome instance is created	Browser window opens, ready to navigate	-	PASS
2	Browser navigates to 'https://www.example.com'	Example.com homepage is loaded in the browser	-	PASS
3	Add cookie named 'testcookie' with value 'cookievalue123'	Cookie is added to the browser session	-	PASS
4	Retrieve all cookies and check if 'testcookie' with correct value exists	Cookies list includes the added cookie	Assert cookie 'testcookie' with value 'cookievalue123' is present	PASS
5	Delete cookie named 'testcookie'	Cookie 'testcookie' is removed from browser session	-	PASS
6	Retrieve all cookies and verify 'testcookie' is no longer present	Cookies list does not include 'testcookie'	Assert cookie 'testcookie' is absent after deletion	PASS
7	Close browser and end test	Browser window closes	-	PASS

Failure Scenario

Failing Condition: Cookie 'testcookie' is not found after adding or still present after deletion

Execution Trace Quiz - 3 Questions

What does the test verify after adding the cookie?

A That the cookie is deleted immediately

B That the page title changes

C That the cookie named 'testcookie' with value 'cookievalue123' exists in the browser

D That the browser navigates to a new page

Key Result

Always verify cookie presence after adding and confirm removal after deletion to ensure cookie management works correctly.
