onnx_backend_test

This module bundles the small C++ library lib_onnx_backend_test that mirrors the backend test node-case infrastructure from onnx_light.backend.test.case in pure C++. It only depends on lib_onnx_proto and exposes:

• a runtime onnx::onnx_backend_test::Tensor (distinct from onnx::TensorProto) that stores raw element bytes;

• a onnx::onnx_backend_test::TestCase bundle of onnx::ModelProto + expected input/output data sets;

• the onnx::onnx_backend_test::Expect() helper and onnx::onnx_backend_test::CollectTestCases() registry.

• simple_tensor.h
• simple_sequence.h
• test_case.h
• random.h
• cases
• kernels
