tests/plugins/model_providers/test_commandcode_profile.py

"""Unit tests for the CommandCode provider profiles.

CommandCode registers two profiles:

``commandcode``
    ``api_mode=chat_completions`` — OpenAI-compatible.  Defaults to
    ``deepseek/deepseek-v4-pro``. 20+ models via a single base URL.

``commandcode-anthropic``
    ``api_mode=anthropic_messages`` — Anthropic Messages API-compatible.
    Defaults to ``claude-sonnet-4-6``.  Requires Bearer auth recognition
    in ``agent/anthropic_adapter.py``.

Both share ``COMMANDCODE_API_KEY`` and ``https://api.commandcode.ai/provider/v1``.
