# Tests asynchrones { #async-tests }

Vous avez déjà vu comment tester vos applications **FastAPI** en utilisant le `TestClient` fourni. Jusqu'à présent, vous n'avez vu que comment écrire des tests synchrones, sans utiliser de fonctions `async`.

// TestErrHandler - Go testing.T satisfy this interface.
// This makes it easy to run the TestServer from any of the tests.
// Using this interface, functionalities to be used in tests can be
// made generalized, and can be integrated in benchmarks/unit tests/go check suite tests.

`TestClient` 是基于 [HTTPX](https://www.python-httpx.org) 的。幸运的是，我们可以直接使用它来测试 API。

## 示例 { #example }

举个简单的例子，让我们来看一个与[更大的应用](../tutorial/bigger-applications.md)和[测试](../tutorial/testing.md)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/app_a_py310/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")
