FirefoxOptions configuration in Selenium Java - Test Execution Trace

Test Overview

This test opens Firefox browser with customized options using FirefoxOptions. It verifies the browser starts with the specified options and navigates to the correct URL.

Test Code - JUnit

Selenium Java

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.FirefoxOptions;
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.assertEquals;

public class FirefoxOptionsTest {
    private WebDriver driver;

    @BeforeEach
    public void setUp() {
        FirefoxOptions options = new FirefoxOptions();
        options.addArguments("-private"); // Start Firefox in private mode
        options.setHeadless(true); // Run in headless mode
        driver = new FirefoxDriver(options);
    }

    @Test
    public void testNavigateToExample() {
        driver.get("https://example.com");
        String title = driver.getTitle();
        assertEquals("Example Domain", title);
    }

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

Execution Trace - 5 Steps

Step	Action	System State	Assertion	Result
1	Create FirefoxOptions and add '--private-window' argument and set headless mode	FirefoxOptions object configured with private mode and headless true	-	PASS
2	Initialize FirefoxDriver with configured FirefoxOptions	Firefox browser starts in headless private mode	-	PASS
3	Navigate to 'https://example.com'	Browser loads the Example Domain page	-	PASS
4	Get page title and assert it equals 'Example Domain'	Page title is 'Example Domain'	assertEquals("Example Domain", title)	PASS
5	Quit the browser and clean up	Browser closed, WebDriver session ended	-	PASS

Failure Scenario

Failing Condition: FirefoxDriver fails to start with given FirefoxOptions or page title does not match

Execution Trace Quiz - 3 Questions

What does the '--private-window' argument in FirefoxOptions do in this test?

A Starts Firefox in private browsing mode

B Enables headless mode

C Disables JavaScript

D Sets browser window size

Key Result

Always configure browser options explicitly to control test environment, such as private mode and headless, ensuring consistent and isolated test runs.
