/// tip

If you want to call `async` functions in your tests apart from sending requests to your FastAPI application (e.g. asynchronous database functions), have a look at the [Async Tests](../advanced/async-tests.md){.internal-link target=_blank} in the advanced tutorial.

///

## Separating tests { #separating-tests }

In a real application, you probably would have your tests in a different file.

```console
$ pip install httpx
```

///

Імпортуйте `TestClient`.

Створіть `TestClient`, передавши йому Ваш застосунок **FastAPI**.

Створюйте функції з іменами, що починаються з `test_` (це стандартна угода для `pytest`).

Використовуйте об'єкт `TestClient` так само як і `httpx`.

Записуйте прості `assert`-вирази зі стандартними виразами Python, які потрібно перевірити (це також стандарт для `pytest`).
