Capture Screenshot in Selenium

How to Capture Screen Shot in Selenium

Why taking a screenshot?

• Screenshot helps to understand the flow of the Application
• For the failed cases screenshot helps to understand on which page the Test case has failed
• Screenshot is taken to track the execution of Test Cases

The following code will takes the screenshot of the Facebook login page

 import java.io.File;  
 import java.io.IOException;  
 import org.apache.commons.io.FileUtils;  
 import org.openqa.selenium.By;  
 import org.openqa.selenium.JavascriptExecutor;  
 import org.openqa.selenium.OutputType;  
 import org.openqa.selenium.TakesScreenshot;  
 import org.openqa.selenium.WebDriver;  
 import org.openqa.selenium.WebElement;  
 import org.openqa.selenium.chrome.ChromeDriver;  
 import org.openqa.selenium.firefox.FirefoxDriver;  
 import org.testng.annotations.Test;  
 public class screenshot {  
        public static void main(String[] args) throws IOException {  
           // TODO Auto-generated method stub  
           WebDriver a = new FirefoxDriver();  
           a.manage().window().maximize();  
           a.get("https://www.facebook.com");  
           a.findElement(By.xpath(".//*[@id='email']")).sendKeys("learn Automation");  
           TakesScreenshot ts = (TakesScreenshot)a;  
           File Source = ts.getScreenshotAs(OutputType.FILE);  
           FileUtils.copyFile(Source, new File("./screenshot/facebook1234.png"));  
           a.quit();  
      }  
 }  

Notes
1- TakesScreenshot is an interface in selenium and we cannot create a object of interface so we have typecast it
2-Typecasting of TakesScreenshot is done in order to get the object
3-getScreenshotAs is a method which is used to get screen shot as a file/Bytes
4-File is a class in java and its object "source" is used to store the screenshot in buffer memory
5-Again FileUtils is a class in java by which we can use a method called copy file which is used to copy a file stored in buffer memory to a particular project location
6- "./screenshot/facebook.png" :- Here "./" refers to the current project location folder which is Learn Automation

Output



In order to see facebook.pngfile we need to refresh the Learn Automation Project
