How to make pytest timeout fail test instead of stopping whole run on windows?

Question

I wonder if there is a possibility for pytest-timeout(or any other solution) to fail timed out test instead of dropping whole run? Pytest-timeout has timeout method signal which accomplishes exactly what I need but only on Unix systems. Is there anything that might give me same behaviour on windows?

You can create your own timeout decorator

from threading import Thread
import functools


def timeout(seconds):
    def deco(func):
        @functools.wraps(func)
        def wrapper(*args, **kwargs):
            res = [Exception('function [%s] timeout [%s seconds] exceeded!' % (func.__name__, seconds))]

            def new_func():
                try:
                    res[0] = func(*args, **kwargs)
                except Exception as e:
                    res[0] = e

            t = Thread(target=new_func)
            t.daemon = True
            try:
                t.start()
                t.join(seconds)
            except Exception as je:
                print('error starting thread')
                raise je
            ret = res[0]
            if isinstance(ret, BaseException):
                raise ret
            return ret

        return wrapper

    return deco

@timeout(2)
def test_x():
    ...
