time_low = hex_to_bin(arr, 0, 8);
        time_mid = S(hex_to_bin(arr, 9, 4));
        time_hi_and_version = S(hex_to_bin(arr, 14, 4));
        clock_seq_hi_and_reserved = B(hex_to_bin(arr, 19, 2));
        clock_seq_low = B(hex_to_bin(arr, 21, 2));
        node = new byte[6];
        node[0] = B(hex_to_bin(arr, 24, 2));
        node[1] = B(hex_to_bin(arr, 26, 2));
        node[2] = B(hex_to_bin(arr, 28, 2));

因此，要在测试代码中添加这行代码创建新的数据库文件。

```Python hl_lines="16"
{!../../../docs_src/sql_databases/sql_app/tests/test_sql_app.py!}
```

## 覆盖依赖项

接下来，创建覆盖依赖项，并为应用添加覆盖内容。

```Python hl_lines="19-24  27"
{!../../../docs_src/sql_databases/sql_app/tests/test_sql_app.py!}
```

!!! tip "提示"

    `overrider_get_db()` 与 `get_db` 的代码几乎完全一样，只是 `overrider_get_db` 中使用测试数据库的 `TestingSessionLocal`。

## 测试应用

```
mc batch generate alias/ replicate
```

### Start the batch job (returns back the JID)
```
mc batch start alias/ ./replicate.yaml
Successfully start 'replicate' job `E24HH4nNMcgY5taynaPfxu` on '2022-09-26 17:19:06.296974771 -0700 PDT'
```

### List all batch jobs
```
mc batch list alias/
ID                      TYPE            USER            STARTED

Обратите внимание, что параметры внутри функции имеют свой естественный тип данных, и вы, например, можете выполнять обычные манипуляции с датами, такие как:

=== "Python 3.8 и выше"

    ```Python hl_lines="18-19"
    {!> ../../../docs_src/extra_data_types/tutorial001.py!}
    ```

=== "Python 3.10 и выше"

    ```Python hl_lines="17-18"
    {!> ../../../docs_src/extra_data_types/tutorial001_py310.py!}

```Python hl_lines="16"
{!../../../docs_src/sql_databases/sql_app/tests/test_sql_app.py!}
```

## Dependency override

Now we create the dependency override and add it to the overrides for our app.

```Python hl_lines="19-24  27"
{!../../../docs_src/sql_databases/sql_app/tests/test_sql_app.py!}
```
