Create a `TestClient` by passing your **FastAPI** application to it.

Create functions with a name that starts with `test_` (this is standard `pytest` conventions).

Use the `TestClient` object the same way as you do with `httpx`.

Write simple `assert` statements with the standard Python expressions that you need to check (again, standard `pytest`).

/// tip

Tout est basé sur la déclaration de type standard de **Python 3.8** (grâce à Pydantic). Pas de nouvelles syntaxes à apprendre. Juste du Python standard et moderne.

Si vous souhaitez un rappel de 2 minutes sur l'utilisation des types en Python (même si vous ne comptez pas utiliser FastAPI), jetez un oeil au tutoriel suivant: [Python Types](python-types.md){.internal-link target=_blank}.

Vous écrivez du python standard avec des annotations de types:

```Python

Im Moment müssen Sie nur wissen, dass `Annotated` existiert, und dass es Standard-Python ist. 😎

Später werden Sie sehen, wie **mächtig** es sein kann.

### Storage Class

By default, parity for objects with standard storage class is set to `N/2`, and parity for objects with reduced redundancy storage class objects is set to `2`. Read more about storage class support in MinIO server [here](https://github.com/minio/minio/blob/master/docs/erasure/storage-class/README.md).

```
KEY:
storage_class  define object level redundancy

* **Robusto**: Crea codice pronto per la produzione con documentazione automatica interattiva.

### Zusammenfassung

Zusammengefasst deklarieren Sie **einmal** die Typen von Parametern, Body, etc. als Funktionsparameter.

Das machen Sie mit modernen Standard-Python-Typen.

Sie müssen keine neue Syntax, Methoden oder Klassen einer bestimmten Bibliothek usw. lernen.

Nur Standard-**Python+**.

Zum Beispiel für ein `int`:

```Python
item_id: int
```

oder für ein komplexeres `Item`-Modell:

```Python

// should be cleared of x-amz-storage-class, if it is set to STANDARD
func TestRemoveStandardStorageClass(t *testing.T) {
	tests := []struct {
		name     string
		metadata map[string]string
		want     map[string]string
	}{
		{
			name:     "1",
			metadata: map[string]string{"content-type": "application/octet-stream", "etag": "de75a98baf2c6aef435b57dd0fc33c86", "x-amz-storage-class": "STANDARD"},

API changes and other small changes to the standard library go here....
