Why multi-browser testing ensures reach in Selenium Java - Test Execution Impact

Test Overview

This test opens a website in two different browsers (Chrome and Firefox) to verify that the main page title is correct in both. It ensures the website works well across browsers, increasing user reach.

Test Code - JUnit 5 with Selenium WebDriver

Selenium Java

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.junit.jupiter.api.Test;
import static org.junit.jupiter.api.Assertions.assertEquals;

public class MultiBrowserTest {
    WebDriver driver;

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

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

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

Execution Trace Quiz - 3 Questions

Why does the test open the website in both Chrome and Firefox?

A To check the website works correctly in multiple browsers

B To test different URLs

C To compare browser speeds

D To test mobile responsiveness

Key Result

Running tests on multiple browsers ensures your website works well for more users, increasing your reach and catching browser-specific issues early.
