Answer 1

Here is my Java code for Selenium WebDriver. Write the following method and call it during assertion:

protected boolean isElementPresent(By by){
        try{
            driver.findElement(by);
            return true;
        }
        catch(NoSuchElementException e){
            return false;
        }
    }
