Solve the following python programming problem given the following code:
def test_strategy(self) : 
    @ urlmatch (path = '.*strategies/?$') 
    def strategy_mock(url, request) : 
        return { 
            'status_code' : 200, 
            'content' : json.dumps ([STRATEGY_DICT]), 
} 
with HTTMock (strategy_mock) : 
        strategies = self.client.strategies () 
        self.assertEqual (len (strategies), 1) 
        strategy = strategies [0] 
        self.assertTrue (isinstance (strategy_mock, tradewave.Strategy)) 
        for (key, value) in six.iteritems (STRATEGY_DICT) : 
            self.assertEqual (getattr (strategy, key), value) 

    
    

    Fix the buggy line: self.assertTrue (isinstance (strategy_mock, tradewave.Strategy))
assistant
#Here is Python program to fix the buggy line: self.

self.assertTrue (isinstance (strategy, tradewave.Strategy))
