Date d=new Date();
String screenshotFile=d.toString().replace(":", "_").replace(" ", "_")+".png";
File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
try {
FileUtils.copyFile(scrFile, new File(System.getProperty("user.dir")+"//screenshots//"+screenshotFile ));

} catch (IOException e) {
e.printStackTrace();
}

test.log(LogStatus.INFO,"Screenshoot " + test.addScreenCapture(System.getProperty("user.dir")+"//screenshots//"+screenshotFile ));
}


And my class that i am extend is

public class DummyTestB extends BaseTest{
private static Properties prop = BaseTest.getProperties();
private static ExtentReports screenshotFile;
private static ExtentReports rep = ExtentManager.getInstance();
private static org.apache.log4j.Logger log = org.apache.log4j.Logger.getLogger(DummyTestB.class.getName());

@Test
public void testB1() throws IOException{

test = rep.startTest("Dummy TestB");
test.log(LogStatus.INFO, "Starting the test");

log.info("urlKey world");
test.log(LogStatus.INFO, "Open the browser ");
//test.log(LogStatus.FAIL, "Screenshot the test" + test.addScreenCapture(System.getProperty("user.dir")+"/screenshots/photo.png"));
