Stattdessen möchten Sie eine andere Abhängigkeit bereitstellen, die nur während Tests (möglicherweise nur bei einigen bestimmten Tests) verwendet wird und einen Wert bereitstellt, der dort verwendet werden kann, wo der Wert der ursprünglichen Abhängigkeit verwendet wurde.

### Anwendungsfälle: Externer Service

        final String text = prefixQuery.getPrefix().text();

        if (Constants.DEFAULT_FIELD.equals(field)) {
            context.addFieldLog(field, text + "*");
            context.addHighlightedQuery(text);

测试时使用覆盖依赖项返回自定义数据库会话代替正常的依赖项。

本例中，要创建仅用于测试的临时数据库。

## 文件架构

创建新文件 `sql_app/tests/test_sql_app.py`。

因此，新的文件架构如下：

``` hl_lines="9-11"
.
└── sql_app
    ├── __init__.py
    ├── crud.py
    ├── database.py
    ├── main.py
    ├── models.py
    ├── schemas.py
    └── tests
        ├── __init__.py
        └── test_sql_app.py
```

## 创建新的数据库会话

首先，为新建数据库创建新的数据库会话。
