+
+        with self.assertRaises(di.MultipleIpForHostError) as context:
+            di._check_multiple_ips_to_host(config)
+        self.assertEqual(context.exception.current_ip, '192.168.1.1')
+        self.assertEqual(context.exception.new_ip, '192.168.1.2')
+        self.assertEqual(context.exception.hostname, 'host1')
+```
+In the above two examples we can see that multiple mention of assertion without proper debug message. So if any of those fails it will not be identifiable which one failed and why failed.
