Can I test async endpoints with the synchronous TestClient?

Yes! The `TestClient` uses the `anyio` backend to automatically handle spinning up the event loop and resolving your `async def` endpoints. You don't need to write `await client.get()` unless you are using the specialized `AsyncClient` from HTTPX.

How do I clear overrides after a test?

You simply call `app.dependency_overrides.clear()`. If you don't clear them, the mock will persist into the next test, which could cause unpredictable behavior.
