## What it is
pytest-cov is a pytest plugin that adds code coverage measurement to pytest runs, built on top of the coverage package. It provides extras like automatic .coverage file handling, coverage contexts, and pytest-xdist distributed testing support.

## Use cases
- measure code coverage of pytest test suites
- get coverage reports when running tests with pytest-xdist
- track which tests cover which lines with coverage contexts
- combine coverage data from parallel or subprocess test runs
- generate coverage reports as part of CI pipelines

## When to choose
- you use pytest and want coverage without manually running coverage run -m pytest
- you need coverage across distributed or parallel test execution with pytest-xdist
- you want automatic cleanup and merging of .coverage data files
- you want consistent sys.path behavior compared to raw coverage run

## When to avoid
- you don't use pytest as your test runner
- you need coverage for non-Python code
- you prefer configuring coverage.py directly without pytest integration

## Facets
- artifact type: plugin
- maturity: stable
- function: testing, developer-tools
- domain: testing, developer-tools
- platform: python, cli, cross-platform
- tags: pytest-plugin, code-coverage, coverage, pytest-xdist, subprocess-coverage, python
