# Pytest CLI

## Install

```
pip install pytest pytest-asyncio
pytest --help
```

## Usage

Ниже приведен краткий обзор соглашений об именах, чтобы ваш тестовый код можно было обнаружить с помощью pytest:

* Тестовые файлы должны быть названы `test_<something>.py` или `<something>_test.py`.
* Методы и функции тестирования должны быть названы `test_<something>`.
* Тестовые классы должны быть названы `Test<Something>`.

```
pytest       # search into a current directory all functions started from 'test_' or ended with '_test'
pytest path/to/test_1.py path/to/test_2.py 
pytest path/to/test_1.py::test_constructor       # Run the 'test_asdict' function only

```

Запустить только один тест:

```
pytest path/to/test_1.py::test_function
pytest path/to/test_1.py::TestClass::test_method
```

Вывести информацию о тестах

```
-v — подробно
-q — кратко
```

Другие ключи посмотреть можно в статье на habr или `pytest --help`.

## Пример структуры файлов для тестов

```
/tests
   /func            — Functional tests
   /unit            — Unit-tests
   pytest.ini       — (optional) настройки pytest
   conftest.py      — Hook functions and fixtures
```

*Hook functions* являются способом вставки кода в часть процесса выполнения pytest для изменения работы pytest. *Fixtures* — функции, которые будут вызваны до и после выполнения теста (например, для подключения к ресурсу и отключению от него).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://appsecurity.gitbook.io/devops/ppc/ppc-langs/backend/python/testing/pytest-cli.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
