Selenium WebDriver: Handling mouseover and hover events

There are many ways to simulate mouse movement in Selenium WebDriver. A few of the of the ways I have used to date can be seen below.

1. Use the Actions class
2. Hijack the mouse
3. Execute Javascript

Example

Hello world

[C#] Solution 1 : Action class

[Test]

  public void handlingMouseoverEvent()

  {

   driver.Navigate().GoToUrl("http://testautomationengineer.blogspot.com/2013/12/selenium-webdriver-handling-mouseover.html");

   Actions builder = new Actions(driver);

   IWebElement smiley = driver.FindElement(By.Id("hoverOverMe"));

   builder.MoveToElement(smiley).Build().Perform();   

  }

[C#] Solution 2 : Hijack the mouse

[Test]

  public void handlingMouseoverEvent()

  {

   driver.Navigate().GoToUrl("http://testautomationengineer.blogspot.com/2013/12/selenium-webdriver-handling-mouseover.html");

   ILocatable hoverItem = (ILocatable) driver.FindElement(By.Id("hoverOverMe"));

   IMouse mouse = ((IHasInputDevices) driver).Mouse;

   mouse.MouseMove(hoverItem.Coordinates);   

  }

[C#] Solution 3 : Execute Javascript

[Test]

  public void handlingMouseoverEvent()

  {

   driver.Navigate().GoToUrl("http://testautomationengineer.blogspot.com/2013/12/selenium-webdriver-handling-mouseover.html");

   var js = (IJavaScriptExecutor)driver;

            js.ExecuteScript("$('[id=hoverOverMe]').trigger('mouseover')");   

  }

Reference:
