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
