Is it possible to test threads with async topic?

[aldefalco]

I tried to test following:

from pyvows import Vows, expect
from threading import Thread
from time import sleep

class MyThread(Thread):

    def __init__(self, a, b, done):
        super(MyThread, self).__init__()
        self.a = a
        self.b = b
        self.done = done

    def run(self):
        while True:
            sleep(2)
            self.done(self.a+self.b)
            break

def sum_in_thread(a, b, callback):
    t = MyThread(a, b, callback)
    t.start()

def sum(a, b, callback):
    callback(a+b)

@Vows.batch
class ThreadContext(Vows.Context):
    @Vows.async_topic
    def topic(self, callback):
        sum_in_thread(2,2, callback)
        #sum(2,2, callback)

    def should_equal_to_4(self, topic):
        expect(topic[0]).to_equal(4)

It passed but with 0 honored. Is it possible to test this case?

I don't think so... ;(

Ah, I think the problem is a joining main thread.
