Description
Summary
This is the top-level tracking task for work regarding the ExecuTorch Test Infrastructure (Backend Tester, name TBD).
Tasks
- Split model test jobs into one job per model.
- Expose error messages in markdown summary.
- Clean up remaining operators tests failing for reasons outside of backend control or reasonable expectations.
- Move each backend test job into a dedicated workflow. This will make it easier to find specific results.
- Run a small smoke test on the test infrastructure on pull. This will prevent breakages.
- Look into displaying latest summary results on the HUD or other location.
- Investigate using pytest-xdist to recover from native crashes. They currently end the entire test run due to the unrecoverable nature of native crashes / memory corruption.
- Create a summary job to accumulate results for each backend and display top-level metrics (pass percentage for f32 models, operator pass percent).
