Print stack trace during test execution. Works on POSIX not WINDOWS.

stacktrace_signalhandler.py

mport signal
import sys
import traceback

def debug(sig, frame):
    """ This is a modified version of the one posted to http://stackoverflow.com/a/133384/308189
    
    This one only writes the traceback to real stdout as robot framework redirects the stdout
    """
    message  = "\nSignal recieved : \nTraceback:\n"
    message += ''.join(traceback.format_stack(frame))
    sys.__stdout__.write(message+'\n')

signal.signal(signal.SIGUSR1, debug)  # Register handler
# kill -30 pid TO GET IT TO WORK
