Hello again, now I will give a tip of Selenium, for mark the element that you want and before this, you can take a screenshot for evidence.
First you have to import this libraries:
import org.openqa.selenium.By;
import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.WebElement;
After this, you have to call the javascript executor and give the id or other thing for find the element:
JavascriptExecutor js = (JavascriptExecutor) driver; // change the name of your WebDriver
WebElement element = driver.findElement(By.id(“element“)); // change the localizator
js.executeScript(“arguments[0].style.border=’3px solid red'”, element); // change the name of your variable
This is very usefull for mark the element in the page.
So, just this ! Bye bye 🙂

Thanks for the good stuff and it working in Selenium. Have any option to mark an element in Native application (if I use the tool as Appium)?
Hey Sanoj, thanks you 🙂 I used calabash and for now I am using Robotium, but depends what is your project, like I would have chosen Appium here at my work, but they don’t have any iPads and probably will never have, so for this reason I chose Robotium.
