Sie können jetzt Produktionsanwendungen mit **FastAPI** erstellen (und das tun Sie wahrscheinlich schon seit einiger Zeit), Sie müssen nur sicherstellen, dass Sie eine Version verwenden, die korrekt mit dem Rest Ihres Codes funktioniert.

## Ihre `fastapi`-Version pinnen { #pin-your-fastapi-version }

/// tip

Note that the test function is now `async def` instead of just `def` as before when using the `TestClient`.

///

Then we can create an `AsyncClient` with the app, and send async requests to it, using `await`.

This is the equivalent to:

```Python
response = client.get('/')
```

	current atomic.Pointer[testing.TB]
	action  atomic.Int32

// SetLogTB will set the logger to output to tb.
// Call the returned function to disable logging.

	return t.setTB(tb, logMessage)

// SetErrorTB will set the logger to output to tb.Error.
// Call the returned function to disable logging.

## About HTTP status codes { #about-http-status-codes }

/// note

If you already know what HTTP status codes are, skip to the next section.

///

In HTTP, you send a numeric status code of 3 digits as part of the response.

These status codes have a name associated to recognize them, but the important part is the number.
