Solve the following python programming problem given the following code:
def __test_event_fire_ipc_mode_tcp(self) : 
    events = Queue () 
    def get_event(events) : 
        me = event.MinionEvent (self.sub_minion_opts, listen = True) 
        events.put_nowait (me.get_event (wait = 10, tag = 'salttest', full = False)) 
threading.Thread (target = get_event, args = (events,)).start () 
    time.sleep (1) 
    ret = self.run_function ('event.fire', ['event.fire: just test it!!!!', 'salttest'], minion_tgt = 'sub_minion') 
    self.assertTrue (ret) 
    eventfired = events.get (block = True, timeout = 10) 
    self.assertIsNotNone (eventfired) 
    self.assertIn ('event.fire: just test it!!!!', self) 
    ret = self.run_function ('event.fire', ['event.fire: just test it!!!!', 'salttest-miss'], minion_tgt = 'sub_minion') 
    self.assertTrue (ret) 
    with self.assertRaises (Empty) : 
        eventfired = events.get (block = True, timeout = 10) 

    
    

    Fix the buggy line: self.assertIn ('event.fire: just test it!!!!', self)

#Here is Python program to fix the buggy line: self.

self.assertIn ('event.fire: just test it!!!!', eventfired)
