EHBP response bodies are opaque encrypted blobs, so cost cannot be injected into JSON like the normal proxy flow. Instead, surface cost as response headers: X-Routstr-Cost-Msats — total msats charged (bearer + x-cashu) X-Routstr-Cost-Usd — USD equivalent (bearer only) X-Routstr-Input-Cost-Msats — msats attributed to input tokens X-Routstr-Output-Cost-Msats— msats attributed to output tokens - Refactor _compute_ehbp_actual_cost from int→dict to carry full cost breakdown - Add _build_cost_info() and _inject_cost_response_headers() helpers - Capture adjust_payment_for_tokens return in bearer path (was discarded) - Update CORS expose_headers, docs, and unit tests
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
