Feature Request

What is the problem that this feature solves?

Shape inference tests for older opset versions will be replaced with newer opset version if there is a opset bump. The reason is shape_inference_test.py relies on onnx.helper and it will always use the latest opset version to create the ONNX models for testing. Therefore, ONNX should extend the test to cover shape inference test for older opset versions as well.
