Selenium is one of the most popular automation testing framework and has the capability to capture screenshot of a web page. It runs on all major browsers. So, in this particular example, we are going to use Google Chrome. As it can be used in various programming languages like Ruby, Python, Java etc. Hence, In this post, we are going to use it to learn “how to take a web page screenshot in JAVA?”.

Take a Web page screenshot in Java using Selenium Webdriver...!!! Share on X

In this tutorial, we are going to cover below topics:

1. Configure Selenium Webdriver and other required dependencies in the project

2. How to take a screenshot of a web page in Java?

Let’s begin:

1. Add required dependencies into the Project

As we are using Selenium Webdriver, there we first need to configure it into our project either by downloading the Selenium Java Jar file and add it into the classpath or specify the below maven dependency into your maven project.

<dependency>
			<groupId>org.seleniumhq.selenium</groupId>
			<artifactId>selenium-java</artifactId>
			<version>4.0.0-alpha-2</version>
		</dependency>

Also, add below supported dependencies

<dependency>
			<groupId>commons-io</groupId>
			<artifactId>commons-io</artifactId>
			<version>2.6</version>
		</dependency>
		<dependency>
			<groupId>io.github.bonigarcia</groupId>
			<artifactId>webdrivermanager</artifactId>
			<version>3.6.2</version>
		</dependency>

2. Capture Web Page Screenshot in Java

import java.io.File;
import java.io.IOException;
import java.sql.Timestamp;
import java.util.Date;

import org.apache.commons.io.FileUtils;

import org.openqa.selenium.OutputType;
import org.openqa.selenium.TakesScreenshot;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

import io.github.bonigarcia.wdm.WebDriverManager;

public class WebPageScreenshotInJavaUsingSeleniumWebdriver {

    static WebDriver driver;

    public static void main(String[] args) throws IOException {

        //Set ChomeDriver as we are using Chrome Browser in our Example.
        //Either set the ChromeDriver using traditional way by setting it using system property with hardcoded location like below
        //System.setProperty("webdriver.chrome.driver","C://driver/chromedriver.exe"); 

        //Or Use WebDriverManager to setup the chromedriver like below
        WebDriverManager.chromedriver().setup();

        driver = new ChromeDriver();

        //Specify the targetted URL
        String testURL = "https://www.google.com";

        //Access the targetted URL
        driver.get(testURL);

        //Capture screenshot of the web page using TakesScreenshot method
        final File screenShotOutputFile = new File("screenshot_" + generatetimeStampBasedRandomNumber() + ".png").getAbsoluteFile();
        File scrFile = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);
        FileUtils.copyFile(scrFile, screenShotOutputFile);

        System.out.println("Took Screenshot for " + testURL + " saved at " + screenShotOutputFile);

        //Quit the driver
        driver.quit();
    }


    //Method to generate Random number based on DateTimeStamp
    private static String generatetimeStampBasedRandomNumber() {

        Date date = new Date();
        long time = date.getTime();
        Timestamp ts = new Timestamp(time);

        String tst = ts.toString();

        try {
            tst = tst.substring(0, tst.length() - 4);
            tst = tst.replace("-", "");
            tst = tst.replace(" ", "");
            tst = tst.replace(":", "");
        } catch (Exception e) {
            e.printStackTrace();
        }

        return tst;
    }
}

Let’s try to understand the code:

1. Set up the Chrome Driver

WebDriverManager.chromedriver().setup();

driver = new ChromeDriver();

2. Specify the targeted URL and access it through the driver object

String testURL = "https://www.google.com";

driver.get(testURL);

3. Capture screenshot with the help of TakesScreenshot Webdriver Interface and save it

final File screenShotOutputFile = new File("screenshot_" + generatetimeStampBasedRandomNumber() + ".png").getAbsoluteFile();

File scrFile = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);

FileUtils.copyFile(scrFile, screenShotOutputFile);
