## 运行起来 { #run-it }

之后，你只需要安装 `pytest`。

确保你创建并激活一个[虚拟环境](../virtual-environments.md)，然后再安装，例如：

<div class="termy">

```console
$ pip install pytest

---> 100%
```

</div>

他会自动检测文件和测试，执行测试，然后向你报告结果。

执行测试：

<div class="termy">

```console
$ pytest

================ test session starts ================

## Es ausführen { #run-it }

Sie können Ihre Tests wie gewohnt ausführen mit:

<div class="termy">

```console
$ pytest

---> 100%
```

</div>

## Im Detail { #in-detail }

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

{* ../../docs_src/async_tests/app_a_py310/test_main.py hl[7] *}

/// tip | Tipp

You can run your tests as usual via:

<div class="termy">

```console
$ pytest

---> 100%
```

</div>

## In Detail { #in-detail }

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

{* ../../docs_src/async_tests/app_a_py310/test_main.py hl[7] *}

/// tip

Note that the test function is now `async def` instead of just `def` as before when using the `TestClient`.

## Запуск { #run-it }

Ви можете запустити тести як зазвичай:

<div class="termy">

```console
$ pytest

---> 100%
```

</div>

## Докладно { #in-detail }

Маркер `@pytest.mark.anyio` повідомляє pytest, що цю тестову функцію слід викликати асинхронно:

{* ../../docs_src/async_tests/app_a_py310/test_main.py hl[7] *}

/// tip | Порада

<div class="termy">

```console
$ pip install pytest

---> 100%
```

</div>

Dosyaları ve testleri otomatik olarak bulur, çalıştırır ve sonuçları size raporlar.

Testleri şu şekilde çalıştırın:
