## 0.121.2

### Fixes

So, `0.5` would be a valid value. But `0.0` or `0` would not.

And the same for <abbr title="less than"><code>lt</code></abbr>.

## Recap { #recap }

# Async Tests { #async-tests }

You have already seen how to test your **FastAPI** applications using the provided `TestClient`. Up to now, you have only seen how to write synchronous tests, without using `async` functions.

If you manually call `app.openapi()`, you should update the `operationId`s before that.

///

/// warning

If you do this, you have to make sure each one of your *path operation functions* has a unique name.

Even if they are in different modules (Python files).

///

## Exclude from OpenAPI { #exclude-from-openapi }

By default, **FastAPI** will return the responses using `JSONResponse`.

You can override it by returning a `Response` directly as seen in [Return a Response directly](response-directly.md){.internal-link target=_blank}.

<div class="termy">

```console
$ pip install "pwdlib[argon2]"

---> 100%
```

</div>

/// tip

With `pwdlib`, you could even configure it to be able to read passwords created by **Django**, a **Flask** security plug-in or many others.

Aber selbst wenn Sie die **Daten ausfüllen** und auf „Ausführen“ klicken, werden aufgrund der Tatsache, dass die Dokumentationsoberfläche mit **JavaScript** arbeitet, die Cookies nicht gesendet, und Sie werden eine **Fehlermeldung** sehen, als ob Sie keine Werte eingegeben hätten.

///

```txt
Hello, World from Flask!
```

Und wenn Sie auf <a href="http://localhost:8000/v2" class="external-link" target="_blank">http://localhost:8000/v2</a> gehen, sehen Sie die Response von FastAPI:

```JSON
{
    "message": "Hello World"

						filterMap[k] = envVarPrefix
					}
				} else {
					filterMap[k] = envVarPrefix
				}
			}
		}
	}

	for k, v := range filterMap {
		seen.Add(strings.TrimPrefix(k, v))
	}

	seen.Remove(Default)
	targets := seen.ToSlice()
	sort.Strings(targets)
	targets = append([]string{Default}, targets...)

	return targets, nil
}
