## What it is
A pytest plugin that provides a `mocker` fixture wrapping the mock package's patching API. It automatically undoes mocks after each test and adds utilities like spy and stub with pytest-style introspection.

## Use cases
- mock functions in pytest tests
- patch os.remove in a unit test
- spy on method calls during testing
- create stubs for pytest test cases
- automatically undo patches after each test
- replace unittest.mock boilerplate in pytest

## When to choose
- you write tests with pytest and need mocking
- you want automatic patch cleanup between tests
- you prefer a fixture-based API over context managers and decorators

## When to avoid
- you don't use pytest as your test runner
- you need mocking features outside of pytest
- you already prefer raw unittest.mock with no wrapper

## Facets
- artifact type: plugin
- maturity: stable
- function: mocking, testing
- domain: testing, developer-tools
- platform: python, cli
- tags: pytest-plugin, pytest-fixture, test-doubles, spy, stub
