Mouse hover (moveToElement) in Selenium Java - Test Execution Trace

Test Overview

This test performs a mouse hover action on a menu item using Selenium WebDriver in Java. It verifies that the submenu becomes visible after hovering.

Test Code - JUnit with Selenium WebDriver

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.interactions.Actions;
import org.junit.Assert;

public class MouseHoverTest {
    private WebDriver driver;

    @Before
    public void setUp() {
        driver = new ChromeDriver();
        driver.manage().window().maximize();
        driver.get("https://example.com/menu");
    }

    @Test
    public void testMouseHoverShowsSubMenu() {
        WebElement menu = driver.findElement(By.id("menu-item"));
        Actions actions = new Actions(driver);
        actions.moveToElement(menu).perform();

        WebElement subMenu = driver.findElement(By.id("submenu-item"));
        Assert.assertTrue(subMenu.isDisplayed());
    }

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

Execution Trace - 7 Steps

Step	Action	System State	Assertion	Result
1	Test starts and Chrome browser opens	Browser window is maximized and ready	-	PASS
2	Navigates to https://example.com/menu	Page with menu loaded	-	PASS
3	Finds the menu item element by id 'menu-item'	Menu item element is located on the page	-	PASS
4	Performs mouse hover action on the menu item using Actions.moveToElement().perform()	Mouse pointer is over the menu item, submenu should appear	-	PASS
5	Finds the submenu item element by id 'submenu-item'	Submenu element is located on the page	-	PASS
6	Checks if submenu item is displayed using isDisplayed()	Submenu is visible on the page	Assert.assertTrue(subMenu.isDisplayed()) verifies submenu visibility	PASS
7	Test ends and browser closes	Browser closed, resources released	-	PASS

Failure Scenario

Failing Condition: Submenu element is not found or not visible after mouse hover

Execution Trace Quiz - 3 Questions

What Selenium method is used to perform the mouse hover action?

A Actions.moveToElement(element).perform()

B WebDriver.findElement()

C driver.get()

D element.click()

Key Result

Always verify that the element you want to interact with is present and visible before performing actions like mouse hover. Use explicit waits if needed to ensure the page is ready.
