`main.py` 파일 안에 **FastAPI** app 을 만들었습니다:

{* ../../docs_src/app_testing/main.py *}

### 테스트 파일

테스트를 위해 `test_main.py` 라는 파일을 생성할 수 있습니다. 이 파일은 동일한 Python 패키지(즉, `__init__.py` 파일이 있는 동일한 디렉터리)에 위치할 수 있습니다.

# Does it send mock mail? (true: no send actually, logging only)
mail.send.mock = false

# SMTP server settings for main: host:port
mail.smtp.server.main.host.and.port = localhost:25

# The prefix of subject to show test environment or not
mail.subject.test.prefix = 

# The common return path of all mail
mail.return.path = root@localhost

Para ejecutar cualquiera de los ejemplos, copia el código a un archivo `main.py`, y comienza `fastapi dev` con:

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> dev <u style="text-decoration-style:solid">main.py</u>

  <span style="background-color:#009485"><font color="#D3D7CF"> FastAPI </font></span>  Starting development server 🚀

No arquivo `main.py` você tem sua aplicação **FastAPI**:


{* ../../docs_src/app_testing/app_a_py39/main.py *}

### Arquivo de teste { #testing-file }

val copyResourcesTemplates = tasks.register<Copy>("copyResourcesTemplates") {
  from("src/main/resources-templates")
  into(layout.buildDirectory.dir("generated/resources-templates"))
  expand("projectVersion" to "${project.version}")
  filteringCharset = Charsets.UTF_8.toString()
}

kotlin {
  sourceSets {
    val main by getting {
      resources.srcDir(copyResourcesTemplates.get().outputs)
    }
  }

O arquivo `main.py` teria:

{* ../../docs_src/async_tests/app_a_py39/main.py *}

O arquivo `test_main.py` teria os testes para para o arquivo `main.py`, ele poderia ficar assim:

{* ../../docs_src/async_tests/app_a_py39/test_main.py *}
