Logging setup in Selenium Python - Test Execution Trace

Test Overview

This test sets up logging for Selenium WebDriver actions and verifies that a log message is correctly recorded when the browser opens and navigates to a URL.

Test Code - unittest

Selenium Python

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

class TestLoggingSetup(unittest.TestCase):
    @classmethod
    def setUpClass(cls):
        # Configure logging
        logging.basicConfig(filename='test_log.log', level=logging.INFO, format='%(asctime)s - %(levelname)s - %(message)s')
        cls.logger = logging.getLogger()

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

    def test_open_google_and_log(self):
        self.logger.info('Test started: Opening Google homepage')
        self.driver.get('https://www.google.com')
        self.logger.info('Navigated to Google homepage')

        # Verify page title contains 'Google'
        title = self.driver.title
        self.logger.info(f'Page title is: {title}')
        self.assertIn('Google', title)

    @classmethod
    def tearDownClass(cls):
        cls.driver.quit()
        cls.logger.info('Test finished: Browser closed')

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

Execution Trace - 7 Steps

Step	Action	System State	Assertion	Result
1	Configure logging to write INFO level messages to 'test_log.log'	Logging is set up with format including timestamp, level, and message	-	PASS
2	Start Chrome WebDriver	Chrome browser window opens	-	PASS
3	Log message: 'Test started: Opening Google homepage'	Log file records the start message	-	PASS
4	Navigate browser to 'https://www.google.com'	Google homepage loads in browser	-	PASS
5	Log message: 'Navigated to Google homepage'	Log file records navigation message	-	PASS
6	Get page title and log it	Page title is retrieved and logged	Verify page title contains 'Google'	PASS
7	Close browser and log message: 'Test finished: Browser closed'	Browser window closes, log file records finish message	-	PASS

Failure Scenario

Failing Condition: Page title does not contain 'Google' or browser fails to open

Execution Trace Quiz - 3 Questions

What does the test verify after navigating to the Google homepage?

A That the page title contains 'Google'

B That the page URL contains 'google.com'

C That the page has a search box

D That the browser window is maximized

Key Result

Setting up logging in tests helps track test progress and diagnose issues by recording key actions and results.
