    * `close()`: Cierra el archivo.
    
    Como todos estos métodos son métodos `async`, necesitas "await" para ellos.
    
    Por ejemplo, dentro de una *path operation function* `async` puedes obtener los contenidos con:
    
    ```Python
    contents = await myfile.read()
    ```

  3. docs/zh/docs/tutorial/request-files.md

    `UploadFile` 支持以下 `async` 方法,(使用内部 `SpooledTemporaryFile`)可调用相应的文件方法。
    
    * `write(data)`:把 `data` (`str` 或 `bytes`)写入文件;
    * `read(size)`:按指定数量的字节或字符(`size` (`int`))读取文件内容;
    * `seek(offset)`:移动至文件 `offset` (`int`)字节处的位置;
        * 例如,`await myfile.seek(0) ` 移动到文件开头;
        * 执行 `await myfile.read()` 后,需再次读取已读取内容时,这种方法特别好用;
    * `close()`:关闭文件。
    
    因为上述方法都是 `async` 方法,要搭配「await」使用。
    
    例如,在 `async` *路径操作函数* 内,要用以下方式读取文件内容:

    **FastAPI** 는 개발자의 편의를 위해 `starlette.testclient` 를 `fastapi.testclient` 로도 제공할 뿐입니다. 이는 단지 `Starlette` 에서 직접 가져오는지의 차이일 뿐입니다.
    
    ///
    
    /// tip | 팁
    
    FastAPI 애플리케이션에 요청을 보내는 것 외에도 테스트에서 `async` 함수를 호출하고 싶다면 (예: 비동기 데이터베이스 함수), 심화 튜토리얼의 [Async Tests](../advanced/async-tests.md){.internal-link target=_blank} 를 참조하세요.
    
    ///
    
    ## 테스트 분리하기
    
    실제 애플리케이션에서는 테스트를 별도의 파일로 나누는 경우가 많습니다.
    
    
    그리고 **FastAPI** 애플리케이션도 여러 파일이나 모듈 등으로 구성될 수 있습니다.
