Der `TestClient` basiert auf [HTTPX](https://www.python-httpx.org) und glücklicherweise können wir es direkt verwenden, um die API zu testen.

## Beispiel { #example }

Betrachten wir als einfaches Beispiel eine Dateistruktur ähnlich der in [Größere Anwendungen](../tutorial/bigger-applications.md) und [Testen](../tutorial/testing.md):

```
.
├── app
│   ├── __init__.py
│   ├── main.py
│   └── test_main.py
```

        checkGetMethod(searchBody, getListEndpointSuffix()).then().body(getJsonPath() + ".size()", equalTo(NUM));
        logger.info("[END] testCreate");
    }

    protected void testRead() {
        logger.info("[BEGIN] testRead");
        // Test: get settings api.
        final Map<String, Object> searchBody = createSearchBody(SEARCH_ALL_NUM);
        List<String> nameList = getPropList(searchBody, getKeyProperty());

## Die Dokumentation testen { #check-the-docs }

Sie können dies in der Dokumentations-UI unter `/docs` testen:
