Jeroen UbbinkandClaude Opus 4.8 ccee76b31e fix(upstream): source litellm context from max_input_tokens only
litellm's max_tokens is the completion cap (it equals max_output_tokens for
~94% of models), not the context window, so falling back to it overstated the
context as the output limit. Take context from max_input_tokens alone; a model
that reports none falls through to the id-based estimate downstream, which is
honest about being a guess rather than mislabelling the output cap.

FastAPI Async Unit Tests

This directory contains async unit tests for the Routstr proxy FastAPI application.

Installation

First, ensure you have the development dependencies installed:

uv pip install -e ".[dev]"

Running Tests

To run all tests:

pytest

To run tests with coverage:

pytest --cov=routstr --cov-report=html

To run specific test files:

pytest tests/test_main.py
pytest tests/test_models.py
pytest tests/test_proxy.py

To run only async tests:

pytest -m asyncio

Test Structure

  • conftest.py - Pytest fixtures and configuration
  • test_main.py - Tests for main app endpoints
  • test_account.py - Tests for wallet/account management endpoints
  • test_proxy.py - Tests for the proxy functionality with mocked upstream
  • test_models.py - Tests for model pricing and data structures

Key Fixtures

  • async_client - Async HTTP client for testing FastAPI endpoints
  • test_session - In-memory SQLite database session for tests
  • test_api_key - Pre-configured API key with balance
  • api_key_with_balance - API key with sufficient balance for proxy tests

Environment Variables

The tests automatically set up required environment variables in conftest.py. No manual configuration needed.

Writing New Tests

  1. Use @pytest.mark.asyncio for async tests
  2. Use the provided fixtures for database and client access
  3. Mock external dependencies (like upstream API calls)
  4. Test both success and error cases
  5. Verify database state changes when applicable
