[None][chore] Remove NIM TRT-Backend Test Lists

[jieli-matrix]

Summary by CodeRabbit

• Tests
  • Reorganized test suite with explicit sections for TRT backend, PyTorch backend, and end-to-end tests
  • Consolidated test selections and streamlined test coverage across feature areas

_{✏️ Tip: You can customize this high-level summary in your review settings.}

Description

The TensorRT backend in NIM is deprecated and will be removed in 1-2 months, with coverage reduction recommended to keep only essential test cases.

Retain only Llama 3.1 8B and 70B on A100 and H100.

GitHub Bot Help

/bot [-h] ['run', 'kill', 'skip', 'reuse-pipeline'] ...

Provide a user friendly way for developers to interact with a Jenkins server.

Run /bot [-h|--help] to print this help message.

See details below for each supported subcommand.

Details

run [--reuse-test (optional)pipeline-id --disable-fail-fast --skip-test --stage-list "A10-PyTorch-1, xxx" --gpu-type "A30, H100_PCIe" --test-backend "pytorch, cpp" --add-multi-gpu-test --only-multi-gpu-test --disable-multi-gpu-test --post-merge --extra-stage "H100_PCIe-TensorRT-Post-Merge-1, xxx" --detailed-log --debug(experimental)]

Launch build/test pipelines. All previously running jobs will be killed.

--reuse-test (optional)pipeline-id (OPTIONAL) : Allow the new pipeline to reuse build artifacts and skip successful test stages from a specified pipeline or the last pipeline if no pipeline-id is indicated. If the Git commit ID has changed, this option will be always ignored. The DEFAULT behavior of the bot is to reuse build artifacts and successful test results from the last pipeline.

--disable-reuse-test (OPTIONAL) : Explicitly prevent the pipeline from reusing build artifacts and skipping successful test stages from a previous pipeline. Ensure that all builds and tests are run regardless of previous successes.

--disable-fail-fast (OPTIONAL) : Disable fail fast on build/tests/infra failures.

--skip-test (OPTIONAL) : Skip all test stages, but still run build stages, package stages and sanity check stages. Note: Does NOT update GitHub check status.

--stage-list "A10-PyTorch-1, xxx" (OPTIONAL) : Only run the specified test stages. Examples: "A10-PyTorch-1, xxx". Note: Does NOT update GitHub check status.

--gpu-type "A30, H100_PCIe" (OPTIONAL) : Only run the test stages on the specified GPU types. Examples: "A30, H100_PCIe". Note: Does NOT update GitHub check status.

--test-backend "pytorch, cpp" (OPTIONAL) : Skip test stages which don't match the specified backends. Only support [pytorch, cpp, tensorrt, triton]. Examples: "pytorch, cpp" (does not run test stages with tensorrt or triton backend). Note: Does NOT update GitHub pipeline status.

--only-multi-gpu-test (OPTIONAL) : Only run the multi-GPU tests. Note: Does NOT update GitHub check status.

--disable-multi-gpu-test (OPTIONAL) : Disable the multi-GPU tests. Note: Does NOT update GitHub check status.

--add-multi-gpu-test (OPTIONAL) : Force run the multi-GPU tests in addition to running L0 pre-merge pipeline.

--post-merge (OPTIONAL) : Run the L0 post-merge pipeline instead of the ordinary L0 pre-merge pipeline.

--extra-stage "H100_PCIe-TensorRT-Post-Merge-1, xxx" (OPTIONAL) : Run the ordinary L0 pre-merge pipeline and specified test stages. Examples: --extra-stage "H100_PCIe-TensorRT-Post-Merge-1, xxx".

--detailed-log (OPTIONAL) : Enable flushing out all logs to the Jenkins console. This will significantly increase the log volume and may slow down the job.

--debug (OPTIONAL) : Experimental feature. Enable access to the CI container for debugging purpose. Note: Specify exactly one stage in the stage-list parameter to access the appropriate container environment. Note: Does NOT update GitHub check status.

For guidance on mapping tests to stage names, see docs/source/reference/ci-overview.md
and the scripts/test_to_stage_mapping.py helper.

kill

kill

Kill all running builds associated with pull request.

skip

skip --comment COMMENT

Skip testing for latest commit on pull request. --comment "Reason for skipping build/test" is required. IMPORTANT NOTE: This is dangerous since lack of user care and validation can cause top of tree to break.

reuse-pipeline

reuse-pipeline

Reuse a previous pipeline to validate current commit. This action will also kill all currently running builds associated with the pull request. IMPORTANT NOTE: This is dangerous since lack of user care and validation can cause top of tree to break.

📝 Walkthrough

Walkthrough

The test list file is reorganized to group tests by functional area (TRT Backend Tests, PyTorch Backend Tests, E2E Tests) instead of a consolidated mixed list. Individual test entries are repositioned or removed. No implementation logic is altered.

Changes

Cohort / File(s)	Summary
Test List Reorganization tests/integration/test_lists/qa/llm_function_nim.txt	Restructured test selections from consolidated entries into feature-area grouped sections (TRT Backend, PyTorch Backend, E2E Tests). Multiple individual test entries removed or relocated; subset retained under updated categories.

Timestamp: 2025-09-09T09:40:45.658Z
Learning: In TensorRT-LLM test lists, it's common and intentional for the same test to appear in multiple test list files when they serve different purposes (e.g., llm_function_core.txt for comprehensive core functionality testing and llm_function_core_sanity.txt for quick sanity checks). This duplication allows tests to be run in different testing contexts.

Learning: In TensorRT-LLM, `tests/integration/test_lists/waives.txt` is specifically for waiving/skipping tests, while other test list files like those in `test-db/` and `qa/` directories are for different test execution contexts (pre-merge, post-merge, QA tests). The same test appearing in both waives.txt and execution list files is intentional - the test is part of test suites but will be skipped due to the waiver.

Timestamp: 2025-07-28T17:06:08.621Z
Learning: In TensorRT-LLM testing, it's common to have both CLI flow tests (test_cli_flow.py) and PyTorch API tests (test_llm_api_pytorch.py) for the same model. These serve different purposes: CLI flow tests validate the traditional command-line workflow, while PyTorch API tests validate the newer LLM API backend. Both are legitimate and should coexist.

Learning: In the TensorRT-LLM test infrastructure, the team prefers simple, direct solutions (like hard-coding directory traversal counts) over more complex but robust approaches when dealing with stable directory structures. They accept the maintenance cost of updating tests if the layout changes.

Learning: In TensorRT-LLM test configuration files, the test scheduling system handles wildcard matching with special rules that prevent duplicate test execution even when the same tests appear in multiple yaml files with overlapping GPU wildcards (e.g., "*b200*" and "*gb200*").

Learning: In TensorRT-LLM's CI infrastructure, pytest skip markers (pytest.mark.skip) are properly honored even when test files have __main__ blocks that call test functions directly. The testing system correctly skips tests without requiring modifications to the __main__ block execution pattern.

For example, some RCCA commands for trtllm-serve may omit the "serve" subcommand while others include it.

🔇 Additional comments (3)

tests/integration/test_lists/qa/llm_function_nim.txt (3)

1-23: Well-organized TRT Backend test reduction aligns with deprecation objectives.

The reorganization groups tests by functional area (TRT Backend, PyTorch Backend, E2E) and the TRT Backend section appropriately retains only Llama 3.1 8B and 70B tests as specified in the PR objectives.

Please verify the following:

1. GPU filtering: The test identifiers don't explicitly mention GPU types (A100/H100). Confirm that GPU filtering for the TRT Backend section is applied through test configuration (e.g., via test markers, execution environment, or external scripts) rather than test selection.

2. Removed tests: The AI summary notes that numerous individual test entries were removed from the previous consolidated list. Please confirm that all removed tests were from the TRT Backend section and that the removal aligns with the deprecation plan (i.e., only Llama 3.1 8B/70B retained).

---

25-224: PyTorch Backend Tests section appropriately expanded to become the primary backend.

The substantial PyTorch backend test coverage (covering Llama 3.1/3.2, Llama 4 variants, Qwen, DeepSeek, Gemma, Mistral, and other models) is appropriate for a backend deprecation scenario and supports the transition from TRT to PyTorch as the default backend.

---

226-267: E2E Tests section provides appropriate integration coverage.

The E2E tests validate end-to-end flows including OpenAI API compatibility, LLM API examples, and quickstart scenarios, providing good integration coverage across both backends.
