9qeklajcandClaude Opus 5 5478fa1d8b fix(models): retry the OpenRouter catalogue fetch before giving up
OpenRouter occasionally answers /models with a truncated body, so the JSON
parse fails. Any exception returned [] for the whole fetch behind one log
line, leaving an enabled upstream advertising zero models, with no retry.

Split into a single-attempt helper plus a wrapper that retries it 3 times
and then returns [] as before. Only /models can fail an attempt; a failing
/embeddings/models logs a warning and contributes nothing, so a secondary
outage cannot empty the catalogue. Only transient errors retry — a 4xx gives
up immediately. The per-attempt timeout drops to 10s so three attempts stay
near the old budget: this fetch blocks startup and the refresh loop.

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
