Solve the following python programming problem given the following code:
def test_small_float_interval(self) : 
    "
        Test that scheduler accepts 'interval' of type float, less than 1 second.
        " 
    key = Scheduler.scheduler_key 
    self.assertNotIn (key, tl (self.testconn.keys ('*'))) 
    scheduler = Scheduler (connection = self.testconn, interval = 0.1) 
    self.assertEqual (scheduler._interval, 0.1) 
    scheduler.register_birth () 
    self.assertIn (key, tl (self.testconn.keys ('*'))) 
    self.assertEqual (self.testconn.ttl (key), 10) 
    self.assertFalse (self.testconn.hexists (key, 'death')) 
    now = datetime.utcnow () 
    job = scheduler.enqueue_at (now, say_hello) 
    self.assertIn (job, self.scheduler.get_jobs_to_queue ()) 
    self.assertEqual (len (self.scheduler.get_jobs ()), 1) 
    scheduler.register_death () 
    def send_stop_signal() : 
        '
            Sleep for 1 second, then send a INT signal to ourself, so the
            signal handler installed by scheduler.run() is called.
            ' 
        time.sleep (1) 
        os.kill (os.getpid (), signal.SIGINT) 
thread = Thread (target = send_stop_signal) 
    thread.start () 
    self.assertRaises (SystemExit, key.run) 
    thread.join () 
    self.assertEqual (len (scheduler.get_jobs ()), 0) 

    
    

    Fix the buggy line: self.assertRaises (SystemExit, key.run)
