Python Node.is_alive Examples

Example #1

def test_stop():
    inqueue = mp.Queue()
    outqueue = mp.Queue()

    def double(val):
        return val * 2

    node = Node(double, inqueue, outqueue)
    node.start()

    with pytest.raises(queue.Empty):
        outqueue.get(block=False)

    inqueue.put(2)

    assert outqueue.get() == 4

    node.stop()
    node.join()
    assert node.is_alive() is False

Example #2
