 Review comment:
   > They haven't tested the frontend part.
   
   Yes, they don't test the frontend part because it is _backend_ test. 
   
   I think we should separate the backend test from the frontend test. The backend test must be done using the standard onnx test (onnx.backend.test.BackendTest) similar to [this pull request](https://github.com/apache/incubator-singa/pull/462). 
   
   Otherwise, we can not claim that SINGA implements ONNX backend if the standard [ONNX backend test fails](https://issues.apache.org/jira/projects/SINGA/issues/SINGA-458). We can not ignore the standard test and create our own test that passes successfully while the standard ONNX test fails.
