## 예시

간단한 예시를 위해 [더 큰 어플리케이션 만들기](../ko/tutorial/bigger-applications.md){.internal-link target=_blank} 와 [테스트](../ko/tutorial/testing.md){.internal-link target=_blank}:에서 다룬 파일 구조와 비슷한 형태를 확인해봅시다:

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

 `main.py`는 아래와 같아야 합니다:

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

`test_main.py` 파일은 `main.py`에 대한 테스트가 있을 텐데, 다음과 같을 수 있습니다:
