I am writing a simple selenium test in which I need to take a screenshot of webpage and save it as PDF. I am using TestNG and PDFbox library with Selenium
Below is my test method:
package com.helper;
import java.io.File;
import java.io.IOException;
import org.apache.pdfbox.pdmodel.PDDocument;
import org.apache.pdfbox.pdmodel.PDPage;
import org.apache.pdfbox.pdmodel.PDPageContentStream;
import org.apache.pdfbox.pdmodel.graphics.image.PDImageXObject;
import org.openqa.selenium.OutputType;
import org.openqa.selenium.TakesScreenshot;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebDriverException;
import org.testng.annotations.Test;
public class ScreenshotPDF {
@Test
public void screenshotPDF(){
WebDriver driver= DriverManager.getWebdriver("chrome");
driver.get("https://www.google.co.in");
try {
File screenshot = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
PDDocument document = new PDDocument();
PDPage page = new PDPage();
document.addPage(page);
PDImageXObject pdi = PDImageXObject.createFromFileByContent(screenshot ,document);
PDPageContentStream contentStream = new PDPageContentStream(document, page);
contentStream.drawImage(pdi,100,100);
document.save("C:/Users/123456/Documents/sample.pdf");
contentStream.close();
document.close();
} catch (WebDriverException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
Here when I run this test with TestNG, I get the following errors in Console:
FAILED: screenshotPDF

I did so much of googling but did not find the solution. Please help me with this error. At least what can be the reason of this error. Thank you in advance.
You need to close the content stream before saving:
PDDocument document = new PDDocument();
PDPage page = new PDPage();
document.addPage(page);
PDImageXObject pdi = PDImageXObject.createFromFileByContent(screenshot ,document);
PDPageContentStream contentStream = new PDPageContentStream(document, page);
contentStream.drawImage(pdi,100,100);
contentStream.close(); // do this before saving!
document.save("C:/Users/123456/Documents/sample.pdf");
document.close();
