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
