Highlight elements in WebDriver during runtime

Question

Can someone please help!

How can I highlight all web elements in following class during test execution in WebDriver? With Selenium RC, it was quite straight forward

Answer 1

I use below code for highlighting in my webdriver java code using javascript executer:

//I make a call below function "flash"

    public static void flash(WebElement element, WebDriver driver) {
        JavascriptExecutor js = ((JavascriptExecutor) driver);
        String bgcolor  = element.getCssValue("backgroundColor");
        for (int i = 0; i <  3; i++) {
            changeColor("rgb(0,200,0)", element, js);
            changeColor(bgcolor, element, js);
        }
    }
    public static void changeColor(String color, WebElement element,  JavascriptExecutor js) {
        js.executeScript("arguments[0].style.backgroundColor = '"+color+"'",  element);

        try {
            Thread.sleep(20);
        }  catch (InterruptedException e) {
        }
     }

Hope that helped :)
