As mentioned above, we can use Actions class for following actions –

Let us see, hot this can be achieved.

In my blog (URL: http://automationtalks.com/), suppose you want to select the sub-menu (Selenium WebDriver) of Menu: Selenium.

                        Actions act = new Actions(driver);

Then, mousehover using actions class, syntax below –

act.moveToElement(driver.findElement(“webelement_Menu_location”)).build().perform();

Now, the submenu should be visible, Then click on the submenu –

driver.findElement(“WebElement_submenu”).click();

Below is the example how can be mouse hover achieved in selenium WebDriver.

package demoPackage1;

import java.util.concurrent.TimeUnit;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.interactions.Actions;
import org.testng.annotations.Test;

public class ActionsClass {
  
  @Test
  public void TestCase() throws InterruptedException{
    
    System.setProperty("webdriver.chrome.driver", "C:\\chromedriver.exe");
    WebDriver driver = new ChromeDriver();
    
    driver.navigate().to("http://automationtalks.com/");
    driver.manage().window().maximize();
    driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
    
    Actions act = new Actions(driver);

    //Define actions class & move to webelement  (Hove mouse to webelement)
    act.moveToElement(driver.findElement(By.xpath("//span[contains(.,'Selenium Tutorial')]"))).build().perform();
    
    //After mouse hover, element form dropdown is appeared, then click on it.
    driver.findElement(By.xpath("//a[contains(.,'Selenium WebDriver')]")).click();
    
    Thread.sleep(3000);
    
    
    driver.close();
    driver.quit();
    
    

    
  }

}

Hope This Helps !!!!
