How can script be executed in Selenium JavascriptExecutor

Question

I have a test.html page, here's code for it.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html>
    <head>
    </head>
    <body>
        <span id="test" onMouseover="alert('1')">this is new one</span>
    </body>
</html>

I want to use Selenium JavascriptExecutor to simulate mouse over event on span in test page, so I wrote code like this:

@Test
public void testJSExecutor(){
    System.setProperty("webdriver.firefox.bin", "C:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe");
    webDriver = new FirefoxDriver();
    webDriver.get("file:\\\\C:/test.html");

    String script = "function test(){var t=document.getElementById('test');"
            + "if( document.createEvent ) {"
            + "var evObj = document.createEvent('MouseEvents');"
            + "evObj.initEvent( 'mouseover', true, false );"
            + "elem.dispatchEvent(evObj);"
            +"} else if( document.createEventObject ) {"
            + "elem.fireEvent('onmouseover');"
            +"}} window.onload=test;";
    jsExecutor = (JavascriptExecutor) webDriver;
    jsExecutor.executeScript(script);
}

But after run this code, no alert prompted.

How could mouse over event be valid so alert could be prompted?

Have you tried using Actions class to do mouseover?

You can simulate the mouse hover action using the below code..

Actions actions = new Actions(driver);
WebElement menuHoverLink = driver.findElement(By.id("test"));
actions.moveToElement(menuHoverLink);
actions.perform();
