Solve the following python programming problem given the following code:
def test_dictionary_bad_key(self) : 
    from gcloud._testing import _Monkey 
    from gcloud.bigtable.happybase import connection as MUT 
    warned = [] 
    def mock_warn(msg) : 
        warned.append (msg) 
option = { 
        'badkey' : None, 
} 
    with _Monkey (MUT, _WARN = mock_warn) : 
        result = self._callFUT (option) 
self.assertEqual (option, None) 
    self.assertEqual (len (warned), 1) 
    self.assertIn ('badkey', warned [0]) 

    
    

    Fix the buggy line: self.assertEqual (option, None)

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

self.assertEqual (result, None)
