Browser profile management in Selenium Java - Test Execution Trace

Test Overview

This test opens a browser with a custom profile to verify that the profile settings are applied correctly. It checks if the browser loads a specific page and confirms the profile's effect.

Test Code - JUnit

Selenium Java

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.FirefoxOptions;
import org.openqa.selenium.firefox.FirefoxProfile;
import org.junit.jupiter.api.AfterEach;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;
import static org.junit.jupiter.api.Assertions.assertTrue;

public class BrowserProfileTest {
    private WebDriver driver;

    @BeforeEach
    public void setUp() {
        FirefoxProfile profile = new FirefoxProfile();
        profile.setPreference("browser.startup.homepage", "https://example.com");
        profile.setPreference("browser.startup.page", 1);
        FirefoxOptions options = new FirefoxOptions();
        options.setProfile(profile);
        driver = new FirefoxDriver(options);
    }

    @Test
    public void testHomePageWithProfile() {
        driver.get("about:blank");
        String currentUrl = driver.getCurrentUrl();
        assertTrue(currentUrl.contains("example.com"), "Browser did not start with the profile homepage");
    }

    @AfterEach
    public void tearDown() {
        if (driver != null) {
            driver.quit();
        }
    }
}

Execution Trace - 6 Steps

Step	Action	System State	Assertion	Result
1	Create FirefoxProfile and set homepage preference to 'https://example.com'	FirefoxProfile object created with custom homepage preference	-	PASS
2	Create FirefoxOptions and assign the custom profile	FirefoxOptions configured with the custom profile	-	PASS
3	Launch FirefoxDriver with the configured options	Firefox browser opens with the custom profile loaded	-	PASS
4	Check initial URL after launch to verify profile homepage	Browser opens to the homepage set in profile	Check if current URL contains 'example.com'	PASS
5	Verify that the browser homepage is 'https://example.com'	Browser URL is 'https://example.com' or contains it	assertTrue(currentUrl.contains("example.com"))	PASS
6	Close the browser and quit the driver	Browser closed, WebDriver session ended	-	PASS

Failure Scenario

Failing Condition: The browser does not load the homepage set in the custom profile

Execution Trace Quiz - 3 Questions

What does the test verify after launching the browser with the custom profile?

A The browser opens a blank page

B The browser homepage is set to 'https://example.com'

C The browser profile is empty

D The browser crashes on startup

Key Result

Always verify that custom browser profiles are correctly loaded by checking the browser state or URL after launch to ensure your preferences are applied.
