Solve the following python programming problem given the following code:
@ patch.object (Collector, 'publish') 
def test_should_work_with_real_data(self, publish_mock) : 
    def se(url) : 
        if ('http://localhost:8778/jolokia/list' in url) : 
            return self.getFixture ('listing') 
else : 
            return self.getFixture ('stats') 
patch_urlopen = patch ('urllib2.urlopen', Mock (side_effect = self)) 
    patch_urlopen.start () 
    self.collector.collect () 
    patch_urlopen.stop () 
    metrics = self.get_metrics () 
    self.setDocExample (collector = self.collector.__class__.__name__, metrics = metrics, defaultpath = self.collector.config ['url_path']) 
    self.assertPublishedMany (publish_mock, metrics) 

    
    

    Fix the buggy line: patch_urlopen = patch ('urllib2.urlopen', Mock (side_effect = self))
