WebElement # getScreenShotAs (OutputType.File) not working

Question

I am trying to use the WebElement # getScreenShotAs (OutputType.FILE) function added to the version of selenium webdriver 2.47.0 on Firefox Browser code

public static void main(String[] args) throws IOException {
        WebDriver driver=new FirefoxDriver();
        driver.manage().window().maximize();
        driver.get("http://automationpractice.com/index.php");
        WebElement element=driver.findElement(By.cssSelector("a[title='Contact Us']"));
        System.out.println(element.getText());
        element.getScreenshotAs(OutputType.FILE);
        File destination=new File("Image.png");
        FileUtils.copyFile(null, destination);
    }

.. But I get below exceptions:

Answer 1

The real cause of the error is that many / most WebDriver implementations do not actually support element-based screenshots , although it has been WebElementexpanding TakesScreenshot since version 2.47.0 . Perhaps someday this will change.

, , , , WebDriver.

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

, , , , , . HtmlUnitDriver.

if (!(getDriver() instanceof TakesScreenshot)) {
    File ssFile = ((TakesScreenshot)(driver)).getScreenshotAs(OutputType.FILE);
    // ...
}

Answer 3

getScreenShotAs() WebElement. , TakesScreenshot. , :

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

Answer 4

- .

File screenS = ((TakesScreenshot)(driver)).getScreenshotAs(OutputType.FILE);
FileUtils.copyFile(screenS, new File("C:\\akshay\\del\\screenshots\\1.jpg"));

replace the above code with

element.getScreenshotAs(OutputType.FILE);
        File destination=new File("Image.png");
        FileUtils.copyFile(null, destination);
