## Usando `TestClient`

## 运行起来

之后，你只需要安装 `pytest`:

<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 ================
platform linux -- Python 3.6.9, pytest-5.3.5, py-1.8.1, pluggy-0.13.1

///

## 実行

後は、`pytest` をインストールするだけです:

<div class="termy">

```console
$ pip install pytest

---> 100%
```

</div>

ファイルを検知し、自動テストを実行し、結果のレポートを返します。

以下でテストを実行します:

<div class="termy">

```console
$ pytest

================ test session starts ================
platform linux -- Python 3.6.9, pytest-5.3.5, py-1.8.1, pluggy-0.13.1

import pytest
from fastapi import FastAPI
from fastapi.testclient import TestClient

from .utils import needs_pydanticv2


@pytest.fixture(name="client")
def get_client():
    app = FastAPI()

    from pydantic import BaseModel, computed_field

    class Rectangle(BaseModel):
        width: int
        length: int

        @computed_field
        @property
        def area(self) -> int:

## Запуск тестов

Далее Вам нужно установить `pytest`:

<div class="termy">

```console
$ pip install pytest

---> 100%
```

</div>

Он автоматически найдёт все файлы и тесты, выполнит их и предоставит Вам отчёт о результатах тестирования.

Запустите тесты командой `pytest` и увидите результат:

<div class="termy">

```console
$ pytest

///

## Executá-lo

Você pode executar os seus testes normalmente via:

<div class="termy">

```console
$ pytest

---> 100%
```

</div>

## Em Detalhes

O marcador `@pytest.mark.anyio` informa ao pytest que esta função de teste deve ser invocada de maneira assíncrona:

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