# This script collects tensorrt_llm unit tests and transform them into TensorRT TURTLE form.
#
# Usage:
# 1. build and install tensorrt_llm python package
# 2. install pytest `pip3 install pytest`
# 3. run `python3 scripts/collect_unittests.py` in tensorrt_llm root directory.
# 4. update the collected tests into TensorRt TURTLE test.
#    - check python list `LLM_UNIT_TESTS` in `<tensorrt repo>/tests/trt-test-defs/turtle/defs/llm/test_llm_unittests.py`.
