Da sich diese Datei im selben Package befindet, können Sie relative Importe verwenden, um das Objekt `app` aus dem `main`-Modul (`main.py`) zu importieren:

```Python hl_lines="3"
{!../../../docs_src/app_testing/test_main.py!}
```

... und haben den Code für die Tests wie zuvor.

## Testen: erweitertes Beispiel

private fun mainFiles(): List<File> {
  val directories =
    listOf(
      "$prefix/samples/guide/src/main/java/okhttp3/guide",
      "$prefix/samples/guide/src/main/java/okhttp3/recipes",
      "$prefix/samples/guide/src/main/java/okhttp3/recipes/kt",
    ).map { File(it) }

  return directories.flatMap {
    it.listFiles().orEmpty().filter { f -> f.isFile }.toList()
  }
}

```
.
├── app
│   ├── __init__.py
│   ├── main.py
│   └── test_main.py
```

The file `main.py` would have:

```Python
{!../../../docs_src/async_tests/main.py!}
```

The file `test_main.py` would have the tests for `main.py`, it could look like this now:

```Python
{!../../../docs_src/async_tests/test_main.py!}
```

## Run it

You can run your tests as usual via:

NAME                   ADDRESSES PORT  MATCH DESTINATION
listener/main_internal           0     ALL   Cluster: inbound-vip|8100|http|httpbin.default.svc.cluster.local
listener/main_internal           0     ALL   Cluster: inbound-vip|8000|http|httpbin.default.svc.cluster.local
listener/main_internal           0     ALL   Cluster: encap
listener/main_internal           0     ALL   Cluster: encap

# Advanced User Guide

## Additional Features

The main [Tutorial - User Guide](../tutorial/index.md){.internal-link target=_blank} should be enough to give you a tour through all the main features of **FastAPI**.

In the next sections you will see other options, configurations, and additional features.

!!! tip
    The next sections are **not necessarily "advanced"**.

    And it's possible that for your use case, the solution is in one of them.

!!! note "Nota"
    O comando `uvicorn main:app` se refere a:

    * `main`: o arquivo `main.py` (o "módulo" Python).
    * `app`: o objeto criado no arquivo `main.py` com a linha `app = FastAPI()`.
    * `--reload`: faz o servidor reiniciar após mudanças de código. Use apenas para desenvolvimento.

Na saída, temos:

.
├── app
│   ├── __init__.py
│   ├── main.py
│   └── test_main.py
```

Because this file is in the same package, you can use relative imports to import the object `app` from the `main` module (`main.py`):

```Python hl_lines="3"
{!../../../docs_src/app_testing/test_main.py!}
```

...and have the code for the tests just like before.

## Testing: extended example

[19515] [INFO] Application startup complete.
```

</div>


让我们看看每个选项的含义：

* `main:app`：这与 Uvicorn 使用的语法相同，`main` 表示名为"`main`"的 Python 模块，因此是文件 `main.py`。 `app` 是 **FastAPI** 应用程序的变量名称。
     * 你可以想象 `main:app` 相当于一个 Python `import` 语句，例如：

        ```Python
        from main import app
        ```

     * 因此，`main:app` 中的冒号相当于 `from main import app` 中的 Python `import` 部分。
