<div class="termy">

```console
$ pytest

---> 100%
```

</div>

## Details

Der Marker `@pytest.mark.anyio` teilt pytest mit, dass diese Testfunktion asynchron aufgerufen werden soll:

```Python hl_lines="7"
{!../../../docs_src/async_tests/test_main.py!}
```

!!! tip "Tipp"

{!../../../docs_src/async_tests/test_main.py!}
```

## Run it

You can run your tests as usual via:

<div class="termy">

```console

---> 100%
```

</div>

## In Detail

The marker `@pytest.mark.anyio` tells pytest that this test function should be called asynchronously:

```Python hl_lines="7"

The end result is that the item paths are now:

* `/items/`
* `/items/{item_id}`

...as we intended.

* They will be marked with a list of tags that contain a single string `"items"`.
    * These "tags" are especially useful for the automatic interactive documentation systems (using OpenAPI).
* All of them will include the predefined `responses`.

It will be clearly marked as deprecated in the interactive docs:

Check how deprecated and non-deprecated *path operations* look like:

```console
$ gunicorn main:app --workers 4 --worker-class uvicorn.workers.UvicornWorker --bind 0.0.0.0:80

[19499] [INFO] Starting gunicorn 20.1.0
[19499] [INFO] Listening at: http://0.0.0.0:80 (19499)

[19515] [INFO] Booting worker with pid: 19515

```console
$ pip install "hypercorn[trio]"
---> 100%
```

</div>

### Run with Trio

Then you can pass the command line option `--worker-class` with the value `trio`:

<div class="termy">

```console
$ hypercorn main:app --worker-class trio
```

</div>

And that will start Hypercorn with your app using Trio as the backend.
