Description

tests/integration/test_lists/waives.txt has carried a directory-level entry unittest/_torch/executor SKIP (https://nvbugs/6800103) since #19381 (2026-09-18). #19382 fixed that bug the same day but removed only its specific skips, so the directory-level line stayed and every test under unittest/_torch/executor has been skipped in CI since.

Running the tree on current main with the line removed: 2436 passed, 54 failed, all deterministic and code-level. This PR replaces the blanket entry with waives for exactly the failing tests so the other ~2400 run again:

  • test_kv_cache_budget_split.py: class-level waives for TestSplitGpuBudgetForDraft and TestExternalDrafterKvDtype, tracked under the existing https://nvbugs/6800223 (same stale-fixture root cause as its original test; the existing test-level line is kept).
  • test_mamba_cache_manager.py: 16 test functions (every parametrization fails) whose SimpleNamespace config lacks the mapping attribute _util.get_kv_cache_manager_cls now reads. The other 151 tests in the file pass.
  • test_kv_cache_v2_vocab_size.py: 11 parametrizations (exact node ids, since the other 13 params pass) whose fixture lacks _max_cuda_graph_batch_size.
  • test_pytorch_model_engine.py::PyTorchModelEngineTestCase::test_prepare_tp_inputs_with_helix_parallelism: the base AttentionMetadata.update_helix_param does not accept the helix_owned_new_tokens keyword model_engine now passes.

The last three groups are tracked under https://nvbugs/6818710.

Test Coverage

Waive-list-only change. The un-waived executor unit tests run in the CPU-Generic unit-test stages of the regular pipeline.

PR Checklist

  • PR title follows the template.
  • PR description explains the change and the tracking bugs.
  • Test lists updated (this PR is the test-list change).

Dev Engineer Review

Updates tests/integration/test_lists/waives.txt with targeted waivers for exactly 54 known executor test failures. Removes the directory-level _torch/executor waiver and an obsolete derived-layer-type waiver. No source or API changes are present. Review findings are unavailable.

QA Engineer Review

The change modifies only tests/integration/test_lists/waives.txt. It adds targeted waivers for failures in four executor test files and restores unaffected executor tests to CPU-Generic stages. Reported CI runs completed successfully. Coverage verdict: sufficient.

Per-File QA Perspective

  • tests/integration/test_lists/waives.txt: Limits skipped executor coverage to known failures. No test-db/ or manual-QA list update is indicated.

Walkthrough

The integration waiver list adds 30 targeted executor and KV-cache test waivers. It removes the broad _torch/executor waiver and specific GPU-budget coverage.

…st waives

The directory-level waive added in NVIDIA#19381 for https://nvbugs/6800103 was
left in place after NVIDIA#19382 fixed that bug, so every test under
unittest/_torch/executor has been skipped in CI since 2026-09-18.

Running the tree on main with the line removed gives 2436 passed and
54 failed. Replace the blanket entry with waives for exactly the failing
tests, so the rest of the tree runs again:

- test_kv_cache_budget_split.py: class-level waives for
  TestSplitGpuBudgetForDraft and TestExternalDrafterKvDtype, tracked
  under the existing https://nvbugs/6800223 (same stale-fixture cause).
- test_mamba_cache_manager.py: 16 test functions whose fixture lacks
  the `mapping` attribute production now reads.
- test_kv_cache_v2_vocab_size.py: 11 parametrizations whose fixture
  lacks `_max_cuda_graph_batch_size`.
- test_pytorch_model_engine.py: test_prepare_tp_inputs_with_helix_parallelism,
  base update_helix_param signature lacks helix_owned_new_tokens.

The last three are tracked under https://nvbugs/6818710.

main already carries the line and PR NVIDIA#19533 replaces it with per-test
waives; the bug it cites is closed. waives.txt is untouched relative to
the merge base again.
