Unable to take screenshot using CEF with Selenium

[shweta]

I am using Selenium to automate the CEF application. I am successfully able to perform operations like click etc. But not able to take the screenshot using Selenium driver. As it is very much required feature for automation.

Can someone please help me out on taking the screenshot of CEF application using Selenium.

I'm using the following -
1) CEF application - Sample application provided by CEF (link - https://bitbucket.org/chromiumembedded/ ... eDriver.md)
2) selenium jar - selenium-server-standalone-3.0.1
3) cef_binary_3.2924.1564.g0ba0378_windows64_client
4) chromedriver
Find the below code -
-----------------------------------------------------------------------------------
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions;
import org.openqa.selenium.TakesScreenshot;
import org.openqa.selenium.OutputType;

public class Example {
public static void main(String[] args) {
// Path to the ChromeDriver executable.
System.setProperty("webdriver.chrome.driver", "D:/CEFTesting/chromedriver.exe");

// Path to the CEF executable.
ChromeOptions options = new ChromeOptions();
options.setBinary("D:/CEFTesting/cef_binary_3.2924.1564.g0ba0378_windows64_client/Release/cefclient.exe");

WebDriver driver = new ChromeDriver(options);
driver.get("http://www.google.com/xhtml");
sleep(3000); // Let the user actually see something!
WebElement searchBox = driver.findElement(By.name("q"));
searchBox.sendKeys("ChromeDriver");
searchBox.submit();
sleep(5000); // Let the user actually see something!

String screenshotBase64 = ((TakesScreenshot) driver).getScreenshotAs(OutputType.BASE64);
System.out.println(screenshotBase64);
sleep(5000); // Let the user actually see something!
driver.quit();
}
static void sleep(int time) {
try { Thread.sleep(time); } catch (InterruptedException e) {}
}
}
