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 configurationtest_main.py- Tests for main app endpointstest_account.py- Tests for wallet/account management endpointstest_proxy.py- Tests for the proxy functionality with mocked upstreamtest_models.py- Tests for model pricing and data structures
Key Fixtures
async_client- Async HTTP client for testing FastAPI endpointstest_session- In-memory SQLite database session for teststest_api_key- Pre-configured API key with balanceapi_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
- Use
@pytest.mark.asynciofor async tests - Use the provided fixtures for database and client access
- Mock external dependencies (like upstream API calls)
- Test both success and error cases
- Verify database state changes when applicable
