### 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

如果您有许多可能经常更改的设置，可能在不同的环境中，将它们放在一个文件中，然后从该文件中读取它们，就像它们是环境变量一样，可能非常有用。

Então seria muito fácil fornecer uma configuração diferente durante a execução dos testes sobrescrevendo a dependência de `get_settings`:

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

Na sobrescrita da dependência, definimos um novo valor para `admin_email` quando instanciamos um novo objeto `Settings`, e então retornamos esse novo objeto.

        return getContext().withAnonymousCredentials();
    }
