how to get a screenshot for failure tests with method name of failure test - selenium

Question

With the listeners how can we solve it.Give me a better solution.I tried using with Listners but it is not giving the method name of failure test, it giving the screenshot name with current method name.for example if a test is failed in one class i want that class method name only.but it is giving execution method as screen shot name
public class Invoke {
public static WebDriver driver;
public static void invoking() throws Exception {
System.setProperty("webdriver.chrome.driver",
"E:\\AK\\Selenium files\\chromedriver_win32 (1)\\chromedriver.exe");
driver = new ChromeDriver();
driver.manage().window().maximize();
driver.get("facebook.com/");
driver.manage().window().maximize();
driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
driver.findElement(By.xpath("akdhd")).click();
}
}
public class Excecution {
#Test public static void m() throws Exception {
Invoke.invoking();
String val=ExcelDynamic.r("C:\\Users\\PC\\Desktop\\facebook.xlsx", "Sheet1", 1, 1);
System.out.println(val);
}
This code is in another class
public static void screen(String Filepath) throws Exception {
TakesScreenshot ts = ((TakesScreenshot) driver);
File fi = ts.getScreenshotAs(OutputType.FILE);
String img = Thread.currentThread().getStackTrace()[2].getMethodName() + ".jpg";
FileUtils.copyFile(fi, new File(Filepath + img));
}
}
i'm calling this method in execution class so it is printing screenshot name m. But i want output name as invoking for screen shot

Answer 1

Below is a utility method that returns the calling method name.
public static String get_calling_method_name() {
return Thread.currentThread().getStackTrace()[2].getMethodName();
}
Hope this solves the issue.

Answer 2

You may try By this,
To change with first index,
String img = Thread.currentThread().getStackTrace()[1].getMethodName() + ".jpg";
Hope it will work.
