Comment 5 for bug 1226374

There may be more, but here's the few examples I came across:

keystone/tests/test_middleware.py:152: self.assertTrue(req.content_type, 'application/json')
keystone/tests/test_v3_oauth1.py:150: self.assertTrue(resp.result.get('consumer').get('id'), consumer_id)
keystone/tests/test_v3_oauth1.py:272: self.assertTrue(entity['id'], self.access_token.key)
keystone/tests/test_v3_oauth1.py:273: self.assertTrue(entity['consumer_id'], self.consumer.key)
keystone/tests/test_v3_oauth1.py:297: self.assertTrue(entity['id'], self.role_id)

tests/v2_0/test_ec2.py:148: self.assertTrue(len(creds), 2)
