The default name is `test_.py` in the parallel path (`transformation.py` → `test_transformation.py`). Many provider dirs use a longer descriptive name instead (e.g. `test_anthropic_chat_transformation.py`) when `test_transformation.py` would be ambiguous across sibling folders or that name is already what the repo uses there; always match the existing test file in the directory you touch rather than introducing another style. Each `*_transformation.py` under `litellm/llms/{provider}/...` ideally has a matching test file in the parallel path. For bug fixes, do not create a new test file; add or extend a regression test in that existing mapped test file. Only create a new test file when adding a new feature (new provider, endpoint, or transformation module) that does not already have a mapped test file; then follow the naming pattern already used in that directory, or `test_.py` if you are the first test there.
