Null pointer exception while taking screenshot in selenium POM with extent report - selenium

Question

A null pointer exception is thrown While trying to take screenshot when the scenario fails. I have an actions class in which i have defiled the capture screenshot method.
public static String capture(WebDriver driver) throws NullPointerException, IOException {
File scrFile;
scrFile = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);
File Dest = new File("D:\\Dinu\\SeleniumReports\\Test" + System.currentTimeMillis() + ".jpeg");
String filepath = Dest.getAbsolutePath();
org.openqa.selenium.io.FileHandler.copy(scrFile, Dest);
return filepath;
}
Extent reports are implemented using Itestlisterner interface. Below given code for which implements the screenshot method given:
public synchronized void onTestFailure(ITestResult result) {
System.out.println((result.getMethod().getMethodName() + " failed!"));
test.get().fail(result.getThrowable());
try {
String screenshotPath = actions.capture(driver);
test.get().addScreenCaptureFromPath(screenshotPath);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
And am getting the below error: Please help in resolving the same.

Answer 1

public static String getScreenhot(WebDriver driver, String screenshotName) throws Exception {
String dateName = new SimpleDateFormat("yyyyMMddhhmmss").format(new Date());
TakesScreenshot ts = (TakesScreenshot) driver;
File source = ts.getScreenshotAs(OutputType.FILE);
//after execution, you could see a folder "FailedTestsScreenshots" under src folder
String destination = System.getProperty("user.dir") + "/FailedTestsScreenshots/"+screenshotName+dateName+".png";
File finalDestination = new File(destination);
FileUtils.copyFile(source, finalDestination);
return destination;
}
#AfterMethod
public void getResult(ITestResult result) throws IOException{
if(result.getStatus() == ITestResult.FAILURE){
logger.log(LogStatus.FAIL, "Test Case Failed is "+result.getName());
logger.log(LogStatus.FAIL, "Test Case Failed is "+result.getThrowable());
//To capture screenshot path and store the path of the screenshot in the string "screenshotPath"
//We do pass the path captured by this mehtod in to the extent reports using "logger.addScreenCapture" method.
String screenshotPath = ExtentReportsClass.getScreenshot(driver, result.getName());
//To add it in the extent report
logger.log(LogStatus.FAIL, logger.addScreenCapture(screenshotPath));
}else if(result.getStatus() == ITestResult.SKIP){
logger.log(LogStatus.SKIP, "Test Case Skipped is "+result.getName());
}
// ending test
//endTest(logger) : It ends the current test and prepares to create HTML report
extent.endTest(logger);
