Solution

According to this question, this is one of those perennial problems Selenium and :hover css

They discuss a couple of solutions, but it looks like the problem is that as Javascript cannot trigger the :hover pseudo class, so Selenium can't either.

You can use webdriver to solve this problem, Webdriver code for mouse over

void mouseOver(String UiLocator) throws Exception

{

element =  driver.findElement(findBy(UiLocator));

Actions builder=new Actions(driver);

builder.moveToElement(element).build().perform();

}
