from fastapi import FastAPI
from fastapi.testclient import TestClient

async def read_items():
    return {"id": "foo"}

    response = client.get("/docs")
    assert response.status_code == 200, response.text
    assert response.headers["content-type"] == "text/html; charset=utf-8"

////

Neste caso o **FastAPI** esperará um corpo como:

```JSON hl_lines="2"
{
    "item": {
        "name": "Foo",
        "description": "The pretender",
        "price": 42.0,
        "tax": 3.2
    }
}
```

ao invés de:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2
}
```

## Recapitulando
