Included review availability: Your plan provides up to 8 included reviews per hour; 6 remain after this review. 📝 WalkthroughWalkthroughThe ONNX conversion tests now cover eleven additional networks: DynUNet, AttentionUnet, BasicUNet, BasicUNetPlusPlus, VNet, HighResNet, DenseNet, ResNet, SEResNet50, UNETR, and FullyConnectedNet. The tests use small model configurations and parameterized CPU and ONNX Runtime settings. A shared helper skips tests when ONNX Runtime is unavailable. Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: ⚪ Minimal · up to This PR expands ONNX export test coverage without changing production behavior, and no actionable merge-blocking risk remains after normal checks and review. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Full details: Description checkExplanation The description follows the repository template, identifies issue Full details: Linked Issues checkExplanation The PR adds the requested ONNX coverage for most architectures in issue Full details: Out of Scope Changes checkExplanation The added architecture tests remain related to the issue objective of expanding ONNX export coverage. FullyConnectedNet and SEResNet50 extend the same test scope and do not introduce unrelated code changes. ✨ Finishing Touches🧪 Generate unit tests (beta)

- Around line 126-127: Update each listed test_dynunet-style test in
tests/networks/test_convert_to_onnx.py at lines 126-127, 153-154, 179-180,
204-205, 230-231, 250-251, 270-271, 297-298, 317-318, 342-343, and 371-372 to
use a matrix with use_trace=True and both use_ort=True and use_ort=False. Keep
the skip conditional limited to the ORT case so the non-ORT conversion runs when
ONNX Runtime is unavailable.
- Around line 57-60: Add Google-style docstrings to every affected definition in
tests/networks/test_convert_to_onnx.py: _check_ort_available at lines 57-60 must
document test_case and its skip behavior, while the definitions at lines
126-128, 153-155, 179-181, 204-206, 230-232, 250-252, 270-272, 297-299, 317-319,
342-344, and 371-373 must document device and use_ort, including applicable
return values and raised exceptions in the appropriate sections.

The ONNX export tests only covered UNet (2D) and SegResNet (3D), leaving regressions in exportability for widely used architectures undetected. Add parameterized ONNX export tests for 10 additional networks: DynUNet, AttentionUnet, BasicUNet, BasicUNetPlusPlus, VNet, HighResNet, DenseNet, ResNet (resnet10), SEResNet50, UNETR, and FullyConnectedNet. All tests use small model configurations and tiny inputs to keep CI fast. Fixes Project-MONAI#9072 Signed-off-by: chhayankjain <chhayank44@gmail.com>

Fixes #9072
Description
The ONNX export test suite (
tests/networks/test_convert_to_onnx.py) only covered 2 out of 40+ network architectures (UNet 2D and SegResNet 3D). This leaves regressions in ONNX exportability for widely used architectures completely undetected.This PR adds parameterized ONNX export tests for 10 additional networks, bringing total coverage to 12 architectures:
All new tests use small model configurations (small filter counts, minimal layers) and tiny input tensors to keep CI runtime low. Each test follows the existing
TESTS_ORTparameterized pattern withuse_trace=Trueandverify=True.Networks with known ONNX-incompatible patterns (e.g., SwinUNETR, AHNet) were intentionally excluded and can be addressed in follow-up work.
