It is based on [HTTPX](https://www.python-httpx.org), which in turn is designed based on Requests, so it's very familiar and intuitive.

With it, you can use [pytest](https://docs.pytest.org/) directly with **FastAPI**.

To use `TestClient`, first install [`httpx`](https://www.python-httpx.org).

# Тестирование { #testing }

Благодаря [Starlette](https://www.starlette.dev/testclient/), тестировать приложения **FastAPI** легко и приятно.

Тестирование основано на библиотеке [HTTPX](https://www.python-httpx.org), которая в свою очередь основана на библиотеке Requests, так что все действия знакомы и интуитивно понятны.

Используя эти инструменты, Вы можете напрямую задействовать [pytest](https://docs.pytest.org/) с **FastAPI**.

The result of calling it is something that can be encoded with the Python standard [`json.dumps()`](https://docs.python.org/3/library/json.html#json.dumps).

It doesn't return a large `str` containing the data in JSON format (as a string). It returns a Python standard data structure (e.g. a `dict`) with values and sub-values that are all compatible with JSON.
