Jeroen UbbinkandClaude Opus 5 e202435ca0 fix(pricing): never serve or route a price built on an unusable rate
A stored rate that is negative or non-finite is not a price, but every guard on
the read path tested truthiness, and `NaN`, `inf` and a negative float are all
truthy. Such a row was advertised in the catalog and built into the routing map,
and the cost calculation cannot bill on it: every request on the model fell
through to the flat maximum reservation, or — for a negative rate — was billed
an amount settlement credits back to the caller.

`has_usable_pricing` asks the question once, across every billable rate, so the
served-catalog and routing backstops answer it identically. One unusable rate
disqualifies the whole price: a positive completion rate must not hide a
negative prompt rate. Zero is untouched — a free model is a real price.

The admin listing (`include_disabled`) is deliberately exempt, or the operator
would lose sight of the row that needs repairing.

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
