import pytest
from fastapi.testclient import TestClient
from inline_snapshot import snapshot

from .main import app

client = TestClient(app)


@pytest.mark.parametrize(
    "path,expected_status,expected_response",
    [
        ("/api_route", 200, {"message": "Hello World"}),
        ("/non_decorated_route", 200, {"message": "Hello World"}),
        ("/nonexistent", 404, {"detail": "Not Found"}),
    ],
)

And in the code, we get a `dict` with all the data sent by the client, **only the data sent by the client**, excluding any values that would be there just for being the default values. To do it we use `exclude_unset=True`. This is the main trick. 🪄

Then we use `hero_db.sqlmodel_update(hero_data)` to update the `hero_db` with the data from `hero_data`.

### Імпортуйте `APIRouter` { #import-the-apirouter }

Тепер імпортуємо інші підмодулі, що мають `APIRouter`:

En el archivo `main.py` tienes tu aplicación de **FastAPI**:


{* ../../docs_src/app_testing/app_a_py310/main.py *}

### Archivo de prueba { #testing-file }

Nehmen wir an, Sie haben eine Dateistruktur wie in [Größere Anwendungen](bigger-applications.md) beschrieben:

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

In der Datei `main.py` haben Sie Ihre **FastAPI**-Anwendung:


{* ../../docs_src/app_testing/app_a_py310/main.py *}


### Testdatei { #testing-file }

因此，為了能在同一個檔案中同時使用它們，我們直接匯入子模組：

{* ../../docs_src/bigger_applications/app_an_py310/main.py hl[5] title["app/main.py"] *}

### 將 `users` 與 `items` 的 `APIRouter` 納入 { #include-the-apirouters-for-users-and-items }

現在，把子模組 `users` 與 `items` 的 `router` 納入：

{* ../../docs_src/bigger_applications/app_an_py310/main.py hl[10:11] title["app/main.py"] *}

/// info | 資訊

`users.router` 是位於 `app/routers/users.py` 檔案內的 `APIRouter`。

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

В файле `main.py` находится Ваше приложение **FastAPI**:


{* ../../docs_src/app_testing/app_a_py310/main.py *}

### Файл тестов { #testing-file }

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

在 `main.py` 檔案中有你的 **FastAPI** 應用：


{* ../../docs_src/app_testing/app_a_py310/main.py *}

### 測試檔案 { #testing-file }

然後你可以建立一個 `test_main.py` 放你的測試。它可以與應用位於同一個 Python 套件（同一個包含 `__init__.py` 的目錄）：

``` hl_lines="5"
.
├── app
│   ├── __init__.py
│   ├── main.py
│   └── test_main.py
