    Screenshot capture in Java Selenium

    While attempting to take a screenshot with Selenium, I keep getting this error? Since fileUtils isn't working for me, I'm using the FileHandler function. Do I need to make any changes?

    My Code :
    ts.getScreenshotAs(OutputType.FILE); ///---> line 54 File src=((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE); File n = new File ("D:\\Failed_Test_Cases\\accessdeniedlogin.png"); FileHandler.copy(src, n); My Result :
    java.lang.NullPointerException: Cannot invoke "org.openqa.selenium.TakesScreenshot.getScreenshotAs(org.openqa.selenium.OutputType)" because "this.ts" is null at StepDefinitions.loginStep.user_clicks_login_button( at ✽.User clicks login button(file:///D:/coach-outlet/src/test/resources/Feature/login.feature:8)

    It looks like the error is occurring on line 54 of your code. Based on the error message, it seems that the "ts" object is null, which is causing the "getScreenshotAs" method to throw a null pointer exception.

    One possible cause for this issue is that the "ts" object is not being properly initialized. In order to take a screenshot using Selenium, you need to first cast the driver object to a TakesScreenshot object. Here's an example of how you might initialize the "ts" object correctly:

    TakesScreenshot ts = (TakesScreenshot)driver;

    Another possible reason for the error is that the driver object is not properly instantiated. Make sure that you have instantiated the driver object and that you are able to navigate to the desired webpage before trying to take a screenshot.

    It is also good to check whether the directory "D:\Failed_Test_Cases" exist or not before trying to save the screenshot.

    Try these steps and let us know if that helps. If you're still running into issues, please provide more information about the environment you're working in (e.g. version of Selenium, version of the browser, etc.) and we'll try to help you out further.


    I find that the harder I work, the more luck I seem to have.

    apturing screenshots using Selenium in Java is a common task for verifying the state of a web page or debugging test failures. Here's an example of how you can capture a screenshot using Selenium WebDriver in Java:

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

    public class ScreenshotExample {
    public static void main(String[] args) {
    // Set the path to the ChromeDriver executable
    System.setProperty("", "path/to/chromedriver");

    // Initialize the WebDriver
    WebDriver driver = new ChromeDriver();

    // Open a web page

    // Capture screenshot
    try {
    // Convert WebDriver object to TakesScreenshot
    TakesScreenshot screenshot = (TakesScreenshot) driver;

    // Capture screenshot as a file
    File screenshotFile = screenshot.getScreenshotAs(OutputType.FILE);

    // Specify the destination path for the screenshot
    File destinationFile = new File("path/to/destination/screenshot.png");

    // Copy the screenshot file to the destination path
    FileUtils.copyFile(screenshotFile, destinationFile);

    System.out.println("Screenshot captured and saved to: " + destinationFile.getAbsolutePath());
    } catch (Exception e) {
    System.out.println("Error capturing screenshot: " + e.getMessage());
    } finally {
    // Close the browser
