Solve the following python programming problem given the following code:
def test_constructor_missing_cluster(self) : 
    from gcloud._testing import _Monkey 
    from gcloud.bigtable.happybase import connection as MUT 
    cluster = _Cluster () 
    timeout = object () 
    get_cluster_called = [] 
    def mock_get_cluster(timeout) : 
        get_cluster_called.append (timeout) 
        return cluster 
with _Monkey (MUT, _get_cluster = mock_get_cluster) : 
        connection = self._makeOne (autoconnect = False, cluster = None, timeout = timeout) 
        self.assertEqual (connection.table_prefix, None) 
        self.assertEqual (connection.table_prefix_separator, '_') 
        self.assertEqual (connection._cluster, get_cluster_called) 
self.assertEqual (get_cluster_called, [timeout]) 

    
    

    Fix the buggy line: self.assertEqual (connection._cluster, get_cluster_called)

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

self.assertEqual (connection._cluster, cluster)
