### Einstellungen und Tests

Dann wäre es sehr einfach, beim Testen ein anderes Einstellungsobjekt bereitzustellen, indem man eine Abhängigkeitsüberschreibung für `get_settings` erstellt:

```Python hl_lines="9-10  13  21"
{!../../../docs_src/settings/app02/test_main.py!}
```

		},
		{
			envName:     "MESOS_CONTAINER_NAME",
			envValue:    "mesos-11111",
			mode:        globalMinioModeErasure,
			expectedStr: fmt.Sprintf("MinIO (%s; %s; %s; %s; source DEVELOPMENT.GOGET DEVELOPMENT.GOGET DEVELOPMENT.GOGET universe-%s", runtime.GOOS, runtime.GOARCH, globalMinioModeErasure, "dcos", "mesos-1111"),
		},
		{
			envName:     "KUBERNETES_SERVICE_HOST",
			envValue:    "10.11.148.5",

```Python hl_lines="16  18-20"
{!../../../docs_src/settings/app02/main.py!}
```

### ⚒ & 🔬

⤴️ ⚫️ 🔜 📶 ⏩ 🚚 🎏 ⚒ 🎚 ⏮️ 🔬 🏗 🔗 🔐 `get_settings`:

```Python hl_lines="9-10  13  21"
{!../../../docs_src/settings/app02/test_main.py!}
```

🔗 🔐 👥 ⚒ 🆕 💲 `admin_email` 🕐❔ 🏗 🆕 `Settings` 🎚, & ⤴️ 👥 📨 👈 🆕 🎚.

⤴️ 👥 💪 💯 👈 ⚫️ ⚙️.

## 👂 `.env` 📁

    ```

### Settings and testing

Then it would be very easy to provide a different settings object during testing by creating a dependency override for `get_settings`:

```Python hl_lines="9-10  13  21"
{!../../../docs_src/settings/app02/test_main.py!}
```

In the dependency override we set a new value for the `admin_email` when creating the new `Settings` object, and then we return that new object.

    ```Python hl_lines="16  18-20"
    {!> ../../../docs_src/settings/app02/main.py!}
    ```

### 设置和测试

然后，在测试期间，通过创建 `get_settings` 的依赖项覆盖，很容易提供一个不同的设置对象：

```Python hl_lines="9-10  13  21"
{!../../../docs_src/settings/app02/test_main.py!}
```

在依赖项覆盖中，我们在创建新的 `Settings` 对象时为 `admin_email` 设置了一个新值，然后返回该新对象。

然后，我们可以测试它是否被使用。

## 从 `.env` 文件中读取设置
