Testing for litellm/

This directory 1:1 maps the the litellm/ directory, and can only contain mocked tests.

The point of this is to:

  1. Increase test coverage of litellm/
  2. Make it easy for contributors to add tests for the litellm/ package and easily run tests without needing LLM API keys.

File name conventions

  • litellm/proxy/test_caching_routes.py maps to litellm/proxy/caching_routes.py
  • test_<filename>.py maps to litellm/<filename>.py
