WebDriver setup (ChromeDriver, GeckoDriver) in Selenium Python - Test Execution Trace

Test Overview

This test opens a browser using Selenium WebDriver with ChromeDriver, navigates to a simple page, and verifies the page title to confirm the setup works correctly.

Test Code - unittest

Selenium Python

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

class TestWebDriverSetup(unittest.TestCase):
    def setUp(self):
        service = Service(executable_path='chromedriver')
        self.driver = webdriver.Chrome(service=service)

    def test_open_google(self):
        self.driver.get('https://www.google.com')
        title = self.driver.title
        self.assertEqual(title, 'Google')

    def tearDown(self):
        self.driver.quit()

if __name__ == '__main__':
    unittest.main()

Execution Trace - 4 Steps

Step	Action	System State	Assertion	Result
1	Test starts and setUp method runs	ChromeDriver executable is located and Chrome browser instance is launched	-	PASS
2	Browser navigates to 'https://www.google.com'	Browser window shows Google homepage	-	PASS
3	Test retrieves page title	Page title is 'Google'	Assert page title equals 'Google'	PASS
4	tearDown method runs and browser closes	Browser window is closed, WebDriver session ends	-	PASS

Failure Scenario

Failing Condition: ChromeDriver executable path is incorrect or ChromeDriver is not installed

Execution Trace Quiz - 3 Questions

What does the test verify after opening the browser?

A The page title is 'Google'

B The browser URL is 'https://www.google.com/search'

C The browser window size is 1024x768

D The page contains a search input field

Key Result

Always verify that the WebDriver executable path is correct and compatible with the browser version to avoid setup failures.
