Logging with Log4j in Selenium Java - Test Execution Trace

Test Overview

This test opens a web page using Selenium WebDriver and logs each step using Log4j. It verifies that the page title matches the expected title, demonstrating how logging helps track test execution.

Test Code - JUnit 5 with Selenium WebDriver and Log4j 2

        String expectedTitle = "Example Domain";
        String actualTitle = driver.getTitle();

        assertEquals(expectedTitle, actualTitle, "Page title should match expected");
        logger.info("Assertion passed: Page title matches expected");

    @AfterEach

Execution Trace - 5 Steps

Step	Action	System State	Assertion	Result
1	Initialize WebDriver and Log4j logger	Logger ready, WebDriver instance created but browser not opened	-	PASS
2	Open browser and navigate to https://example.com	Browser window opened at https://example.com	-	PASS
3	Retrieve page title	Page loaded with title 'Example Domain'	Check if page title equals 'Example Domain'	PASS
4	Assert page title matches expected	Page title is 'Example Domain'	assertEquals('Example Domain', actualTitle)	PASS
5	Close browser and quit WebDriver	Browser closed, WebDriver quit	-	PASS

Failure Scenario

Failing Condition: Page title does not match expected 'Example Domain'

Execution Trace Quiz - 3 Questions

What does the logger record when the browser navigates to the URL?

A Logger records 'Navigated to https://example.com'

B Logger records 'Browser closed'

C Logger records 'Assertion passed'

D Logger records 'Setting up WebDriver'

Key Result

Logging each test step with Log4j helps track test progress and quickly identify where failures occur, improving debugging efficiency.
