In Automation, it is advisable to take screenshots of failed test cases for further analysis and proof of failure. Selenium provides the capability to take screenshot. But, before we see how to capture Screenshot in Selenium, we need to add a dependency in the Maven project.
Recently Selenium has done some changes in recent version so if you are using Selenium 3.6.0 then you need to add below jar to project or if you are using then you can provide below dependency in project.
https://mvnrepository.com/artifact/commons-io/commons-io
To capture a screenshot in Selenium, we can make use of an interface, called TakesScreenshot. This method indicates the driver, that it can capture a screenshot and store it in different ways
TakesScreenshot ts = (TakesScreenshot) driver;
In order to capture screenshot and store it in a particular location, there is a method called “getScreenshotAs“, where OutputType defines the output type for a screenshot.
File source = ts.getScreenshotAs(OutputType.FILE);
Copy file to Desired Location
FileUtils.copyFile(source, newFile("./Screenshots/Selenium" + System.currentTimeMillis() + ".png"));
Let’s see the complete program
import java.io.File;
import java.io.IOException;
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;
public class ScreenshotDemo {
public static void main(String[] args) throws IOException {
System.setProperty("webdriver.chrome.driver", "src\\test\\resources\\webdrivers\\window\\chromedriver.exe");
WebDriver driver = new ChromeDriver();
// Maximize the window
driver.manage().window().maximize();
driver.get("https://configureselenium.blogspot.com/");
// Convert web driver object to TakeScreenshot
TakesScreenshot ts = (TakesScreenshot) driver;
// Call getScreenshotAs method to create image file
File source = ts.getScreenshotAs(OutputType.FILE);
// Copy file at destination
FileUtils.copyFile(source, new File("./Screenshots/Selenium" + System.currentTimeMillis() + ".png"));
System.out.println("the Screenshot is taken");
// close the current browser
driver.quit();
}
}
A folder with name Screenshots created and the screenshot is placed in that folder as you can see the image below
The Screenshot looks like something below
If you don’t want to use Maven Dependency common-io, then you can use FileHandler from
import org.openqa.selenium.io.FileHandler;
FileHandler.copy(source, new File("C:\\Screenshots\\Selenium" + System.currentTimeMillis() + ".png"));
