Each case repeats the same setup block: buildSAConfig, build the manager, add a request, prepare, build tensors, callextend_ngram, assert, shut down.The first failing case stops the rest, so a regression report shows one failure instead of the exact set of broken cases. The repetition also makes the file long and harder to extend.

pattern to multi-case tests that create several managers. Update

17-22: 🩺 Stability & Availability | 🟠 Major | ⚡ Quick winRelease the manager with a fixture or
try/finally.Every test calls
manager.shutdown()as the last statement. If an assertion fails earlier,shutdown()never runs.SuffixAutomatonManagerowns pinned host buffers and a GPU workspace sizedpool_size * state_size, so a failed test leaks that memory into the following tests in the same process. One failure can then cascade into unrelated CUDA OOM failures and hide the original cause.Use a pytest fixture that yields the manager and shuts it down in teardown. Apply the same pattern to the multi-case tests that build several managers.
♻️ Proposed fixture pattern

… into L0 CI - Relocate tests/torch/speculative/test_suffix_automaton.py to tests/unittest/_torch/speculative/: the test-db runner only routes unittest/-prefixed entries (tests/integration/defs/conftest.py), so the old location could never be listed. Pure rename, no content changes. - List the suffix-automaton kernel tests in l0_b200.yml (pre-merge, 1 GPU). - Wire test_kimi_k3_specdec.py::test_kimi_k3_sa_specdec_logits_parity (orphaned since NVIDIA#17327) into l0_gb300_multi_gpus.yml (post-merge, 4 GPUs). It resolves <LLM_MODELS_ROOT>/Kimi-K3 and skips cleanly when absent. - Wire the CPU-only test_kimi_k3_disagg_parity_selftest into l0_cpu.yml. - Fix a stale comment in l0_gb300_multi_gpus.yml (the KDA parity unit tests never load a checkpoint) and a dead sbatch filename in the kimi_k3_disagg_parity.py docstring.

…tests - Add the NVIDIA SPDX header and a module-level CUDA skipif guard so a plain 'pytest tests/unittest/' run on a GPU-less machine skips instead of failing. - Route every SuffixAutomatonManager construction through a make_manager fixture that shuts managers down on teardown: a mid-test assertion failure no longer leaks pinned host buffers / GPU workspace into subsequent tests in the same process. - Assert results in test_manager_extend (token 6 is unseen in the context: no match, zeroed draft - the extend_ngram no-match convention) and after CUDA-graph replay in test_cuda_graph_capture (a match must exist once warmups appended prior 6s; exact values not pinned since they depend on the executed-extend count). - Add coverage for the global_pool_size < max_num_requests ValueError. - Replace the hand-maintained __main__ test registry with pytest.main([__file__]) so direct execution cannot drift. - l0_cpu-listed disagg parity selftest: a missing harness is now a hard failure instead of a silent skip. Declined review suggestions (rationale in the PR discussion): parametrizing the multi-case extend_ngram tests, and removing SAConfig.threshold (the field is consumed by the SA-enhancer product path via eagle3/pard/mtp).

… stale list comment Review feedback (brnguyen2): - test_kimi_k3_sa_specdec_logits_parity: a missing checkpoint is now a hard failure instead of a skip. On the post-merge GB300 stage a skip is indistinguishable from a pass, so a checkpoint dropped from the runners' models mount would silently end this coverage — same reasoning already applied to the harness-existence check in this PR. The checkpoint is verified staged on the CI models share, and the pre-merge --extra-stage run exercises this path before merge. - l0_gb300_multi_gpus.yml: entry comment updated to match (fails, not skips, without the checkpoint). - l0_b200.yml: the suffix-automaton entry comment claimed 'no skip guards', which went stale when the previous review round added the module-level cuda-availability skipif. Comment fixed; the guard is kept because it matches the sibling KDA parity tests' pytestmark convention and protects plain 'pytest tests/unittest/' runs on GPU-less machines. Signed-off-by: Michal Guzek <mguzek@nvidia.com>
…docstring Review feedback (CodeRabbit): the docstring claimed the MoE backend defaults to VANILLA (the reference dequant parity oracle), but the harness defaults KIMI_K3_MOE_BACKEND to AUTO and KimiK3MoERuntime routes the routed-expert backend to TRTLLM regardless of moe_config.backend — the test body's env-block comment already said so. Docstring now matches: TRTLLM backend, parity holds because baseline and spec runs share it. Forcing VANILLA is not an option (the override would not take effect). Signed-off-by: Michal Guzek <mguzek@nvidia.com>
…ts up front The first post-merge GB300 run of the SA logits-parity test failed deep inside tokenizer loading: tiktoken tried to parse 'version https://git-lfs.github.com/spec/v1' as a vocab. Root cause is checkpoint staging, not code: Kimi-K3 is staged from a git-lfs clone, the staging source was hydrated on 2026-08-17, but the GB300 runner's per-cluster models mirror still served the pre-hydration ~130-byte pointer files. The test now scans the resolved checkpoint's top-level files for the LFS pointer magic before spending any engine time, and fails with a message naming the offending files and pointing at mirror re-sync / 'git lfs pull' — instead of a misleading tiktoken traceback after the truncated checkpoint has already been materialized. Validated against the hydrated staging copy (no offenders — the guard will not fire once mirrors sync) and a synthetic pointer file (detected). Signed-off-by: Michal Guzek <mguzek@nvidia.com>

@brnguyen2 , looks like it's also safe to skip? |

Summary
Wires the already-committed Kimi K3 spec-dec test assets into L0 CI and fixes two stale references. Part of TRTLLM-15035 (porting the Kimi K3 regression test plan into automated CI). Pure wiring plus one file relocation — no behavior changes.
Changes
tests/torch/speculative/test_suffix_automaton.pytotests/unittest/_torch/speculative/(puregit mv, no content changes). The test-db runner only routes yml entries starting withunittest/(seetest_unittests_v2parametrization intests/integration/defs/conftest.py), so the old location could never be listed in CI — an oversight from [TRTLLM-11042][feat] Implement suffix automaton on device for spec and support one model with help from @mahmoudhas #11434; the file has been unrunnable-by-CI since. Verified before moving: no basename collision, no conftest dependency, nothing in the repo references the old path, and no list collects the target directory wholesale (each sibling test is listed per-file).l0_b200.yml(pre-merge, 1 GPU). They cover the on-device suffix automaton used by SA speculative decoding (CUDA kernels + CUDA graph capture) and previously ran nowhere.test_kimi_k3_specdec.py::test_kimi_k3_sa_specdec_logits_parityintol0_gb300_multi_gpus.yml(post-merge, 4 GPUs,TIMEOUT (40)). The test landed in [TRTLLM-14814][feat] Kimi K3 serving parsers, chat template, and speculative decoding (suffix automaton + DFlash scaffold) #17327 but was never registered in any list. It runs the SA spec-dec pipeline end to end on the first 4 layers (KDA + first MLA) of the Kimi K3 checkpoint with logits-parity checking against the non-spec baseline — the cheap canary for KDA recurrent-state regressions. It resolves<LLM_MODELS_ROOT>/Kimi-K3and skips cleanly when the checkpoint is not staged.test_kimi_k3_specdec.py::test_kimi_k3_disagg_parity_selftestintol0_cpu.yml(pre-merge).
