Testing Async Code
Example
import pytest
import httpx
@pytest.mark.asyncio
async def test_async_endpoint():
async with httpx.AsyncClient(app=app, base_url="http://test") as client:
resp = await client.get("/api/users")
assert resp.status_code == 200
# pytest.ini
[pytest]
asyncio_mode = auto # auto-detect async tests
@pytest.fixture
async def async_db():
db = await create_test_db()
yield db
await db.close() Pro Tip
Set asyncio_mode = auto in pytest.ini to avoid decorating every async test manually.
