```Python hl_lines="28-29  32"

from fastapi import FastAPI
from fastapi.testclient import TestClient

app = FastAPI()


@app.get("/a/{id}")
async def a(id):
    pass  # pragma: no cover


client = TestClient(app)


def test_openapi_schema():
    response = client.get("/openapi.json")
    assert response.status_code == 200, response.text
    assert response.json() == {
        "openapi": "3.1.0",
        "info": {"title": "FastAPI", "version": "0.1.0"},

from fastapi.testclient import TestClient
from pydantic import BaseModel

app = FastAPI()


class Model(BaseModel):
    pass


class Model2(BaseModel):
    a: Model


class Model3(BaseModel):
    c: Model
    d: Model2


@app.get("/", response_model=Model3)
def f():
    return {"c": {}, "d": {"a": {}}}


client = TestClient(app)


def test_get_api_route():
    response = client.get("/")

```

O valor gerado (yielded) é o que é injetado nas *operações de rota* e outras dependências.

```Python hl_lines="4"
{!../../docs_src/dependencies/tutorial007.py!}
```

O código após o `yield` é executado após a resposta ser entregue:

```Python hl_lines="5-6"
{!../../docs_src/dependencies/tutorial007.py!}
```

Você pode usar funções assíncronas (`async`) ou funções comuns.

from fastapi import FastAPI
from pydantic import BaseModel

app = FastAPI()


class Item(BaseModel):
    name: str
    description: str | None = None
    price: float
    tax: float | None = None
    tags: set[str] = set()


@app.post("/items/", response_model=Item, tags=["items"])
async def create_item(item: Item):
    return item


@app.get("/items/", tags=["items"])
async def read_items():
