Reported symptom: "Test model" in the UI hangs indefinitely, a new
device code appears in the proxy logs, and the whole UI is frozen.
Root cause: the ChatGPT **chat** transformation still used the
filesystem-only ``Authenticator`` unconditionally. When the UI's
``/health/test_connection`` runs in the default ``mode="chat"``:
UI → /health/test_connection (sync wait)
→ litellm.ahealth_check(mode="chat")
→ litellm.acompletion(...)
→ ChatGPTConfig._get_openai_compatible_provider_info(api_key="oauth:X")
→ self.authenticator.get_access_token() # filesystem authenticator
→ _login_device_code() # no tokens on disk → prints a new
# device code and polls for up to 15
# minutes, blocking the request
``ChatGPTResponsesAPIConfig`` already had the ``resolve_authenticator``
dispatch (the PR's original scope), so the responses-mode path was
fine. The chat path was overlooked.
Fix:
- Apply ``resolve_authenticator`` to both call-sites in
``ChatGPTConfig`` (``_get_openai_compatible_provider_info`` and
``validate_environment``). When ``api_key`` carries the ``oauth:``
prefix, both methods now reach for the DB-backed authenticator and
the stored credential — no device-code prompt, no 15-minute hang.
- Extend ``resolve_authenticator`` to the 3-arg shape
``(api_key, litellm_params, fallback)`` so it matches the Copilot
resolver and covers the chat call-site that has ``api_key`` but not
``litellm_params``. Updated the single existing call-site in
``responses/transformation.py`` and the existing unit tests.
- Add a regression test asserting that ``ChatGPTConfig`` never calls
the filesystem authenticator when ``api_key`` is ``oauth:<name>``
(fs_auth is a MagicMock that raises on any attribute access).
170 tests pass; Black + Ruff clean.

In total litellm runs 1000+ tests
[02/20/2025] Update:
To make it easier to contribute and map what behavior is tested,
we've started mapping the litellm directory in tests/test_litellm
This folder can only run mock tests.
