                                     - 2 types of alerts.
        1- HTML Alert: Nothing special with this one. 
          You just locate as WebElement then click.
        2- JS Alert: We cannot locate this web element
           in the HTML code. 
        You have to handle it differently
        - We handle alerts using Alert class
         creating ALERT object and 
        - Alert alert = driver.switchTo().alert();
         There are 3 options :
        - alert.accept();
        - alert.dismiss();
        - alert.sendKeys();
