If you provide code then its helpfull or provide some ideas to solve this problem.

Thanks in advance.

Answer 1

Yes, It is possible.

WebDriver firfoxDriver = new FirefoxDriver();
firfoxDriver.get("https://stackoverflow.com/");
File file = ((TakesScreenshot)firfoxDriver).getScreenshotAs(OutputType.FILE);
// Now you can do whatever you need to do with it, for example copy somewhere
FileUtils.copyFile(file, new File("E:\\Data\\ss.png"));

Answer 2

Or You can use this:

@AfterMethod(alwaysRun=true)
public void catchExceptions(ITestResult result){
Calendar calendar = Calendar.getInstance();
SimpleDateFormat formater = new SimpleDateFormat("dd_MM_yyyy_hh_mm_ss");
String methodName = result.getName();
if(!result.isSuccess()){
    File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
    try {
        FileUtils.copyFile(scrFile, new File((String)     PathConverter.convert("failure_screenshots/"+methodName+"_"+formater.format(calendar.getTime())+".png")));
        } catch (IOException e1) {
            e1.printStackTrace();
        }
    }
}

Well It's depend on your framework that where the control is going after failing the method.

Suppose in your case it is going in catch exception block then copy that code in catch block.

File file = ((TakesScreenshot)firfoxDriver).getScreenshotAs(OutputType.FILE);
FileUtils.copyFile(file, new File("YOUR PATH"+Filename+.JPG));

You can use Itestlistener in testng to take screenshot. testng has an in built function by which you can take screenshot when it fails.

Just create a seperate listerner class and paste this code:

public class listeners implements ITestListener{

//This "Base " is the main class where you can pass the result of test case and write the //code for screenshot  
//I cam creating an object so I can access the method that I created for screenshot in this base class.  
//I am also getting the result name so I can identify which test case it got failed


Base b = new Base();
public void onTestFailure(ITestResult result) { 
    try {
        //Getting the result name by result.getName() method         
        b.getScreenshot( result.getName());
        System.out.println("The Failed test is=="+result.getName());
    }   
    catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();  
    }  
}   
}  

I created this getScreenshot method in the base class and passing the result name

public class Base {

public WebDriver InitializeDr() throws IOException {  
    //Creating the method to take screenshot in the Base class    
    public void getScreenshot(String result) throws IOException
    {  
        File dest=new File("D:\\Work\\KT\\Scr Shot\\"+result+"test.png");  
        File src=((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);  
        FileUtils.copyFile(src, dest);  
    }  
}  
}
