### Без объявленного типа возврата { #no-return-type }

Вы также можете опустить тип возврата. FastAPI использует [`jsonable_encoder`](./encoder.md) для преобразования данных и их отправки.

關於如何把資料傳給後端（使用 `httpx` 或 `TestClient`），更多資訊請參考 [HTTPX 文件](https://www.python-httpx.org)。

/// info

請注意，`TestClient` 接收的是可轉為 JSON 的資料，而不是 Pydantic models。

如果你的測試裡有一個 Pydantic model，並想在測試時把它的資料送給應用，你可以使用[JSON 相容編碼器](encoder.md)中介紹的 `jsonable_encoder`。

///

## 執行 { #run-it }

接下來，你只需要安裝 `pytest`。

請先建立並啟用一個[虛擬環境](../virtual-environments.md)，然後安裝，例如：

<div class="termy">

```console

### Sem tipo de retorno { #no-return-type }

Você também pode omitir o tipo de retorno. O FastAPI então usará o [`jsonable_encoder`](./encoder.md) para converter os dados em algo que possa ser serializado para JSON e depois enviá-los como JSON Lines.
