Add DATABASE_POOL_SIZE / DATABASE_MAX_OVERFLOW / DATABASE_POOL_TIMEOUT, consumed like every other typed env var through the pydantic Settings (constrained Fields, defaults 5/10/30 matching SQLAlchemy's own baseline so leaving them unset is behaviour-neutral). An out-of-range or non-integer value fails validation and refuses to boot — the same fail-loud behaviour a malformed DATABASE_URL already has — rather than silently starting up misconfigured. create_db_engine sizes the pool from these and logs the effective values at startup so they can be confirmed from the boot output during an incident. In-memory SQLite (StaticPool, which rejects the pool kwargs) is detected and built without them. pool_pre_ping is deliberately not exposed: the default backend is a local SQLite file with no network peer to drop idle connections, so it would add a SELECT 1 per checkout for no benefit — and it detects dead connections, not the live-but-wedged ones behind the exhaustion this series addresses. These knobs are infrastructure the node needs before it can open a DB session, so they can never be sourced from the DB (chicken-and-egg). A new ENV_ONLY_FIELDS set keeps them out of the persisted settings blob and stops a DB value from shadowing env in both SettingsService.initialize and .update, so env stays authoritative.

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
