JIT kernel tests live under `python/sglang/jit_kernel/tests/`. **CI does not run `pytest` in that directory directly.** The unified runner `test/run_suite.py` discovers every `test_*.py` there (and every `bench_*.py` under `benchmark/`), collects `register_*_ci(...)` calls by **statically parsing each file's AST**, and executes the selected suite. Every test file must register at least one CUDA entry or the collector fails its sanity check.
- **PR / per-commit CUDA suites** (see `test/run_suite.py` → `PER_COMMIT_SUITES`): JIT unit tests use `stage-b-kernel-unit-1-gpu-large` (see `.github/workflows/pr-test-jit-kernel.yml`: `python3 run_suite.py --hw cuda --suite stage-b-kernel-unit-1-gpu-large`).
- **PR / per-commit CUDA suites** (see `test/run_suite.py` → `PER_COMMIT_SUITES`): JIT unit tests use `stage-b-kernel-unit-1-gpu-large` on H100 and `stage-b-kernel-unit-1-gpu-b200` on B200/SM100 paths (see `.github/workflows/pr-test-jit-kernel.yml`). Multi-GPU JIT tests use `stage-b-kernel-unit-8-gpu-h200`.
- **Nightly kernel suite**: `nightly-kernel-1-gpu` with `--nightly` — typically used with `SGLANG_JIT_KERNEL_RUN_FULL_TESTS=1` in CI for expanded parameter grids (see `python/sglang/jit_kernel/utils.py` → `should_run_full_tests` / `get_ci_test_range`). Wired in `.github/workflows/nightly-test-nvidia.yml` (e.g. `python3 run_suite.py --hw cuda --suite nightly-kernel-1-gpu --nightly --continue-on-error`).

**Run like CI** (from repo root):
```bash
cd test && python3 run_suite.py --hw cuda --suite stage-b-kernel-unit-1-gpu-large
(cd test && python3 run_suite.py --hw cuda --suite stage-b-kernel-unit-1-gpu-large)
# For B200/SM100-specific coverage:
(cd test && python3 run_suite.py --hw cuda --suite stage-b-kernel-unit-1-gpu-b200)
```
For fast iteration you can still run `pytest` on a single file locally; CI coverage is via `run_suite.py`.
