org.openqa.selenium.interactions.MoveTargetOutOfBoundsException: (x, y) is out of bounds while MouseHover with GeckoDriver Firefox Selenium

Question

I am learning how to automate tests with Selenium WebDriver, however I got stuck and cannot make dropdown menu to work in Firefox. The same code runs perfectly fine in Chrome.

The site I am practicing on is: http://www.executeautomation.com/demosite/index.html and I want to click the following item from menu: Automation Tools > Selenium > Selenium WebDriver.

The error message suggest that the web element may not be loaded on the screen yet, so I have implemented some method to wait with every execution until the element shows up:

public static void ImplicitWait(WebDriver driver){
    driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
}

but it did not helped.

Then I read that it is better to "pipe" those moveToElement() methods instead of performing them one by one. So I changed this:

action.moveToElement(menu).perform();
action.moveToElement(selenium).perform();
action.moveToElement(seleniumWebDriver).click().build().perform();

to one line. At this point it started to work on Chrome, but I am still struggling to make it work on Firefox.

The current code looks like this:

System.setProperty("webdriver.gecko.driver", "C:\\Drivers\\geckodriver-v0.24.0-win64\\geckodriver.exe");
System.setProperty("webdriver.firefox.bin", "C:\\Program Files\\Mozilla Firefox\\firefox.exe");
WebDriver driver = new FirefoxDriver();

ImplicitWait(driver);

driver.navigate().to("http://executeautomation.com/demosite/index.html");

WebElement menu = driver.findElement(By.id("Automation Tools"));
WebElement selenium = driver.findElement(By.id("Selenium"));
WebElement seleniumWebDriver = driver.findElement(By.id("Selenium WebDriver"));

Actions action = new Actions(driver);
action.moveToElement(menu).moveToElement(selenium).moveToElement(seleniumWebDriver).click().build().perform();

As I mentioned above the same works fine when I switch to Chrome, but with Firefox I get the error message:

Exception in thread "main" org.openqa.selenium.interactions.MoveTargetOutOfBoundsException: (-9862, 206) is out of bounds of viewport width (1283) and height (699)

I am using: * Firefox v66.0.2 * Java v1.8.0_201 * Selenium Java v3.141.59 * GeckoDriver v0.24.0

Please help.

Answer 1

The main issue with the Web Application is that the HTML DOM attains document.readyState equals to complete even before the sub-menu element with text as Selenium WebDriver gets rendered. Hence you see the error as:

Exception in thread "main" org.openqa.selenium.interactions.MoveTargetOutOfBoundsException: (-4899, 91) is out of bounds of viewport width (1366) and height (664)

Solution

So an ideal solution would be:

• Induce WebDriverwait for the titleIs() Execute Automation
• Induce WebDriverwait for the menu element with text as Automation Tools
• Induce WebDriverwait for the sub-menu element with text as Selenium
• Induce WebDriverwait for the sub-menu elementToBeClickable with text as Selenium
• You can use the following solution:

• Code Block:

      import org.openqa.selenium.By;
      import org.openqa.selenium.WebDriver;
      import org.openqa.selenium.firefox.FirefoxDriver;
      import org.openqa.selenium.interactions.Actions;
      import org.openqa.selenium.support.ui.ExpectedConditions;
      import org.openqa.selenium.support.ui.WebDriverWait;
  
      public class MouseHoverFirefox {
  
          public static void main(String[] args) {
  
              System.setProperty("webdriver.gecko.driver", "C:\\Utility\\BrowserDrivers\\geckodriver.exe");
              WebDriver driver=new FirefoxDriver();
              driver.get("http://www.executeautomation.com/demosite/index.html");
              new WebDriverWait(driver, 20).until(ExpectedConditions.titleIs("Execute Automation"));
              new Actions(driver).moveToElement(new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//span[@id='Automation Tools']")))).build().perform();
              new Actions(driver).moveToElement(new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//li[@class='active has-sub']/a/span//following::ul[1]/li[@class='has-sub']/a/span[@id='Selenium']")))).build().perform();
              new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//li[@class='active has-sub']/a/span//following::ul[1]/li/a/span[@id='Selenium']//following::ul[1]/li/a/span[text()='Selenium WebDriver']"))).click();
          }
      }

Please try the below code(if you are inside frame , you need to come out and use below code):

WebDriver driver=new ChromeDriver();
JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript("window.scrollBy(0,400)");

Answer 3

Use WebDriverWait and try the following code.

driver.get("http://executeautomation.com/demosite/index.html");
WebDriverWait wait = new WebDriverWait(driver, 20);
WebElement menu= wait.until(ExpectedConditions.elementToBeClickable(By.id("Automation Tools")));

Actions action = new Actions(driver);
action.moveToElement(menu).build().perform();
WebElement selenium =wait.until(ExpectedConditions.elementToBeClickable(By.id("Selenium"))); 
action.moveToElement(selenium).build().perform();
WebElement seleniumWebDriver =wait.until(ExpectedConditions.elementToBeClickable(By.id("Selenium WebDriver")));
action.moveToElement(seleniumWebDriver).click().build().perform();

Answer 4

I've observed the same issue with geckodriver and Actions class. Although you can go with following code

System.setProperty("webdriver.gecko.driver", "C:\\Drivers\\geckodriver-v0.24.0-win64\\geckodriver.exe");
WebDriver driver = new FirefoxDriver();
driver.get("http://executeautomation.com/demosite/index.html");
driver.manage().timeouts().implicitlyWait(15, TimeUnit.SECONDS);
WebElement mainmenu = driver.findElement(By.xpath("//li[@class='active has-sub']"));
WebElement submenu = driver.findElement(By.xpath("//li[@class='has-sub'] [contains(.,'Selenium')]"));
WebElement intendedLink = driver.findElement(By.xpath("//li[@class='has-sub'] [contains(.,'Selenium')]//li[contains(.,'Selenium WebDriver')]"));

Actions action =new Actions(driver);
action.moveToElement(mainmenu).clickAndHold().build().perform();
Thread.sleep(1000);
action.moveToElement(submenu).clickAndHold().build().perform();
Thread.sleep(1000);
intendedLink.click();

Code is working fine at my end. let me know if any issue.

Note: Keep the mouse pointer out of web page screen else it override the current focus.

Try using it -

action.moveToElement(menu).build().perform();
Thread.sleep(500);
moveToElement(selenium).build().perform();
Thread.sleep(500);
moveToElement(seleniumWebDriver).click().build().perform();
