# Asynchrone Tests { #async-tests }

Sie haben bereits gesehen, wie Sie Ihre **FastAPI**-Anwendungen mit dem bereitgestellten `TestClient` testen. Bisher haben Sie nur gesehen, wie man synchrone Tests schreibt, ohne `async`-Funktionen zu verwenden.

## Пример { #example }

В качестве простого примера, давайте рассмотрим файловую структуру, схожую с описанной в [Большие приложения](../tutorial/bigger-applications.md){.internal-link target=_blank} и [Тестирование](../tutorial/testing.md){.internal-link target=_blank}:

```
.
├── app
│   ├── __init__.py
│   ├── main.py
│   └── test_main.py
```

Файл `main.py`:

{* ../../docs_src/async_tests/app_a_py39/main.py *}

app.include_router(router)


client = TestClient(app)


def test_a():
    response = client.get("/a")
    assert response.status_code == 200, response.text
    assert response.json() == "a"


def test_b():
    response = client.get("/b")
    assert response.status_code == 200, response.text
    assert response.json() == "b"


def test_c():
    response = client.get("/c")

        assertTrue(result.getWarnings().get(1).contains("test:g"));
    }

    @Test
    void testBadDependencyManagementScope() throws Exception {
        SimpleProblemCollector result = validate("bad-dependency-management-scope.xml");

        assertViolations(result, 0, 0, 1);

        assertContains(result.getWarnings().get(0), "test:g");
    }

    @Test
    void testBadDependencyVersion() throws Exception {

`TestClient` 是基于 <a href="https://www.python-httpx.org" class="external-link" target="_blank">HTTPX</a> 的。幸运的是，我们可以直接使用它来测试API。

## 示例

举个简单的例子，让我们来看一个[更大的应用](../tutorial/bigger-applications.md){.internal-link target=_blank}和[测试](../tutorial/testing.md){.internal-link target=_blank}中描述的类似文件结构：

```
.
├── app
│   ├── __init__.py
│   ├── main.py
│   └── test_main.py
```

文件 `main.py` 将包含:

{* ../../docs_src/async_tests/main.py *}
