Die Datei `main.py` hätte als Inhalt:

```Python

Die Datei `test_main.py` hätte die Tests für `main.py`, das könnte jetzt so aussehen:

## 🏃 ⚫️

👆 💪 🏃 👆 💯 🐌 📨:

<div class="termy">

```console

В вашем FastAPI приложении, импортируйте и вызовите `uvicorn` напрямую:

```Python hl_lines="1  15"
{!../../../docs_src/debugging/tutorial001.py!}
```

### Описание `__name__ == "__main__"`

Главная цель использования `__name__ == "__main__"` в том, чтобы код выполнялся при запуске файла с помощью:

<div class="termy">

```console
$ python myapp.py
```

</div>

```Python hl_lines="11  19"
{!../../../docs_src/sub_applications/tutorial001.py!}
```

### Check the automatic API docs

Now, run `uvicorn` with the main app, if your file is `main.py`, it would be:

<div class="termy">

```console
$ uvicorn main:app --reload

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

Dans votre application FastAPI, importez et exécutez directement `uvicorn` :

```Python hl_lines="1  15"
{!../../../docs_src/debugging/tutorial001.py!}
```

### À propos de `__name__ == "__main__"`

Le but principal de `__name__ == "__main__"` est d'avoir du code qui est exécuté lorsque votre fichier est appelé avec :

<div class="termy">

```console
$ python myapp.py
```

</div>

## 🤙 `uvicorn`

👆 FastAPI 🈸, 🗄 & 🏃 `uvicorn` 🔗:

### 🔃 `__name__ == "__main__"`

👑 🎯 `__name__ == "__main__"` ✔️ 📟 👈 🛠️ 🕐❔ 👆 📁 🤙 ⏮️:

<div class="termy">

```console
$ python myapp.py

</div>

✋️ 🚫 🤙 🕐❔ ➕1️⃣ 📁 🗄 ⚫️, 💖:

```Python
from myapp import app

    unixScriptTemplate.from(layout.projectDirectory.file("../../../platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt"))
    windowsScriptTemplate.from(layout.projectDirectory.file("../../../platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/windowsStartScript.txt"))
}

configurations {
    create("gradleScriptsElements") {

<span style="color: green;">INFO</span>:     Application startup complete.
```

</div>

!!! note
    `uvicorn main:app` 命令含义如下:

    * `main`：`main.py` 文件（一个 Python「模块」）。
    * `app`：在 `main.py` 文件中通过 `app = FastAPI()` 创建的对象。
    * `--reload`：让服务器在更新代码后重新启动。仅在开发时使用该选项。


在输出中，会有一行信息像下面这样：

```hl_lines="4"

import org.junit.platform.launcher.listeners.SummaryGeneratingListener

fun main(vararg args: String) {
  System.setProperty("junit.jupiter.extensions.autodetection.enabled", "true")
