The `TestClient` is based on [HTTPX](https://www.python-httpx.org), and luckily, we can use it directly to test the API.

## Example { #example }

Varsayılan olarak tekil değerler query parametresi olarak yorumlandığı için, ayrıca `Query` eklemeniz gerekmez; şöyle yazmanız yeterlidir:

```Python
q: str | None = None
```

Örneğin:

{* ../../docs_src/body_multiple_params/tutorial004_an_py310.py hl[28] *}


/// info | Bilgi

Dans ces cas, vous pouvez utiliser la technique Python « unpacking » d'un `dict` avec `**dict_to_unpack` :

```Python
old_dict = {
    "old key": "old value",
    "second old key": "second old value",
}
new_dict = {**old_dict, "new key": "new value"}
```

Ici, `new_dict` contiendra toutes les paires clé-valeur de `old_dict` plus la nouvelle paire clé-valeur :

```Python
{
    "old key": "old value",

    ## Usage

    Create an instance object and use that object as the dependency in `Depends()`.

    The dependency result will be a string containing the key value.

    ## Example

    ```python
    from fastapi import Depends, FastAPI
    from fastapi.security import APIKeyQuery

    app = FastAPI()

    query_scheme = APIKeyQuery(name="api_key")


    @app.get("/items/")

```Python
commons: Annotated[dict, Depends(common_parameters)]
```

Mais comme nous utilisons `Annotated`, nous pouvons stocker cette valeur `Annotated` dans une variable et l’utiliser à plusieurs endroits :

{* ../../docs_src/dependencies/tutorial001_02_an_py310.py hl[12,16,21] *}

Read more about it in the [FastAPI docs about returning a custom Response](https://fastapi.tiangolo.com/advanced/response-directly/#returning-a-custom-response)

You can import it directly from `fastapi`:

```python
from fastapi import Response
```

It includes:

* `Query()`
* `Path()`
* `Body()`
* `Cookie()`
* `Header()`
* `Form()`
* `File()`

You can import them all directly from `fastapi`:

```python
from fastapi import Body, Cookie, File, Form, Header, Path, Query
```

::: fastapi.Query

::: fastapi.Path

::: fastapi.Body

::: fastapi.Cookie

::: fastapi.Header

::: fastapi.Form
