# Generate Clients

As **FastAPI** is based on the OpenAPI specification, you get automatic compatibility with many tools, including the automatic API docs (provided by Swagger UI).

One particular advantage that is not necessarily obvious is that you can **generate clients** (sometimes called <abbr title="Software Development Kits">**SDKs**</abbr> ) for your API, for many different **programming languages**.

## OpenAPI Client Generators

After you have tests, then you can upgrade the **FastAPI** version to a more recent one, and make sure that all your code is working correctly by running your tests.

If everything is working, or after you make the necessary changes, and all your tests are passing, then you can pin your `fastapi` to that new recent version.

## About Starlette

The main thing you need to run a **FastAPI** application (or any other ASGI application) in a remote server machine is an ASGI server program like **Uvicorn**, this is the one that comes by default in the `fastapi` command.

There are several alternatives, including:

!!! tip
    You could reduce duplication in that code by putting it in a function and using it from both `database.py` and `tests/test_sql_app.py`.

    For simplicity and to focus on the specific testing code, we are just copying it.

## Create the database

!!! info
    To use `TestClient`, first install <a href="https://www.python-httpx.org" class="external-link" target="_blank">`httpx`</a>.

    E.g. `pip install httpx`.

Import `TestClient`.

Create a `TestClient` by passing your **FastAPI** application to it.

Create functions with a name that starts with `test_` (this is standard `pytest` conventions).

Use the `TestClient` object the same way as you do with `httpx`.

    但是依然建议你使用上面提到的主意，使用多个类而不是这些参数。

    这是因为即使使用 `response_model_include` 或 `response_model_exclude` 来省略某些属性，在应用程序的 OpenAPI 定义（和文档）中生成的 JSON Schema 仍将是完整的模型。

    这也适用于作用类似的 `response_model_by_alias`。

```Python hl_lines="31  37"
{!../../../docs_src/response_model/tutorial005.py!}
```

!!! tip
    `{"name", "description"}` 语法创建一个具有这两个值的 `set`。

    等同于 `set(["name", "description"])`。

    それでも、これらのパラメータではなく、複数のクラスを使用して、上記のようなアイデアを使うことをおすすめします。

    これは`response_model_include`や`response_mode_exclude`を使用していくつかの属性を省略しても、アプリケーションのOpenAPI（とドキュメント）で生成されたJSON Schemaが完全なモデルになるからです。

    同様に動作する`response_model_by_alias`にも当てはまります。

```Python hl_lines="31 37"
{!../../../docs_src/response_model/tutorial005.py!}
```

!!! tip "豆知識"
    `{"name", "description"}`の構文はこれら２つの値をもつ`set`を作成します。
