First Selenium script in Selenium Python - Test Execution Trace

Test Overview

This test opens a browser, goes to example.com, checks the page title, and closes the browser. It verifies the page loaded correctly by checking the title text.

Test Code - unittest

Selenium Python

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

class TestExampleDotCom(unittest.TestCase):
    def setUp(self):
        options = Options()
        options.add_argument('--headless')  # Run browser in headless mode
        service = Service()
        self.driver = webdriver.Chrome(service=service, options=options)

    def test_title(self):
        self.driver.get('https://example.com')
        title = self.driver.title
        self.assertEqual(title, 'Example Domain')

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

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

Execution Trace - 7 Steps

Step	Action	System State	Assertion	Result
1	Test starts - unittest framework initializes test case	No browser open yet	-	PASS
2	Browser opens in headless mode using ChromeDriver	Chrome browser running without UI	-	PASS
3	Navigates to 'https://example.com'	Browser loads example.com homepage	-	PASS
4	Reads page title	Page title is 'Example Domain'	Check if title equals 'Example Domain'	PASS
5	Assertion checks title equality	Title matches expected text	assertEqual(title, 'Example Domain')	PASS
6	Browser closes	No browser running	-	PASS
7	Test ends successfully	Test framework reports success	-	PASS

Failure Scenario

Failing Condition: Page title does not match 'Example Domain' due to navigation failure or page change

Execution Trace Quiz - 3 Questions

What does the test check after opening the browser?

A The page contains a login form

B The browser window size

C The page title is 'Example Domain'

D The URL contains 'test'

Key Result

Always verify key page elements like the title to confirm the page loaded correctly before continuing tests.
