/// info

`TestClient` は、Pydanticモデルではなく、JSONに変換できるデータを受け取ることに注意してください。

テストにPydanticモデルがあり、テスト中にそのデータをアプリケーションに送信したい場合は、[JSON互換エンコーダ](encoder.md) で説明されている `jsonable_encoder` が利用できます。

///

## 実行 { #run-it }

その後、`pytest` をインストールするだけです。

[仮想環境](../virtual-environments.md) を作成し、それを有効化してから、例えば以下のようにインストールしてください:

<div class="termy">

この場合は関数が async ではないため、適切な戻り値の型は `Iterable[Item]` です:

{* ../../docs_src/server_sent_events/tutorial001_py310.py ln[28:31] hl[29] *}

### 戻り値の型なし { #no-return-type }

戻り値の型を省略することもできます。FastAPI は [`jsonable_encoder`](./encoder.md) を使ってデータを変換し、送信します。

{* ../../docs_src/server_sent_events/tutorial001_py310.py ln[34:37] hl[35] *}

## `ServerSentEvent` { #serversentevent }

    available in those versions!


## Version 4.8.0

_2020-07-11_

 *  New: Change `HeldCertificate.Builder` to use its own ASN.1 certificate encoder. This is part
    of our effort to remove the okhttp-tls module's dependency on Bouncy Castle. We think Bouncy
    Castle is great! But it's a large dependency (6.5 MiB) and its security provider feature

`TestClient`는 Pydantic 모델이 아니라 JSON으로 변환될 수 있는 데이터를 받습니다.

만약 테스트 중 Pydantic 모델을 가지고 있고 테스트 중에 애플리케이션으로 해당 데이터를 보내고 싶다면, [JSON 호환 인코더](encoder.md)에 설명되어 있는 `jsonable_encoder`를 사용할 수 있습니다.

///

## 실행하기 { #run-it }

그 후에는 `pytest`를 설치하기만 하면 됩니다.

[가상 환경](../virtual-environments.md)을 만들고, 활성화 시킨 뒤에 설치하세요. 예시:

<div class="termy">

        // Test NTLM Type 1 message handling
        byte[] type1Message = new byte[] { 0x4E, 0x54, 0x4C, 0x4D, 0x53, 0x53, 0x50, 0x00, 0x01, 0x00, 0x00, 0x00 };
        String authHeader = "NTLM " + new String(org.bouncycastle.util.encoders.Base64.encode(type1Message));

        when(request.getHeader("Authorization")).thenReturn(authHeader);
        when(httpSession.getAttribute("NtlmHttpAuth")).thenReturn(null);
