Add pytest infrastructure with API health check tests

[Copilot]

Test issue to verify copilot integration. Adds foundational testing infrastructure.

Changes

• Test suite: Created tests/test_api_health.py with coverage for /healthz endpoint and FastAPI app structure validation
• Pytest config: Added pytest.ini with test discovery patterns, markers (unit/integration/slow), and pydantic deprecation warning filters
• Dependencies: Added httpx==0.27.2 for TestClient support
• Documentation: Added "Running Tests" section to README with usage examples

Implementation

Tests use pytest fixtures for clean app initialization:

@pytest.fixture
def client():
    """Create a test client for the FastAPI app."""
    return TestClient(app)

def test_healthcheck_endpoint(client):
    """Test that the health check endpoint returns OK status."""
    response = client.get("/healthz")
    assert response.status_code == 200
    assert response.json() == {"status": "ok"}

Run with: python -m pytest or python -m pytest -v for verbose output.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• api.scarf.sh
  • Triggering command: /usr/bin/python python -m pytest tests/test_api_health.py -v (dns block)
  • Triggering command: /usr/bin/python python -m pytest tests/ (dns block)
  • Triggering command: /usr/bin/python python -m pytest tests/ -v (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

[Copilot]

Consider adding a scope to the fixture to optimize test performance. Since the TestClient is stateless and doesn't need to be recreated for each test, you could use @pytest.fixture(scope="module") to create it once per test module instead of once per test function.

Suggested change

	@pytest.fixture
	@pytest.fixture(scope="module")

[Copilot]

Consider adding test markers to categorize these tests. Since pytest.ini defines markers for unit, integration, and slow tests, you should mark these tests appropriately. For example, @pytest.mark.unit for test_api_structure and @pytest.mark.integration for test_healthcheck_endpoint would help with selective test execution.

[Copilot]

The blank line between the response retrieval and assertions is inconsistent with Python style conventions. Consider removing this blank line to keep the related assertions grouped together with the API call they're testing.
