Coverage.py measures code coverage, typically during test execution. It uses
the code analysis tools and tracing hooks provided in the Python standard
library to determine which lines are executable, and which have been executed.

Coverage.py runs on these versions of Python:

.. PYVERSIONS

* Python 3.10 through 3.15 rc1, including free-threading.
* PyPy3 versions 3.10 and 3.11.

Documentation is on `Read the Docs`_.  Code repository and issue tracker are on
`GitHub`_.

## AI interpretation — verify before relying

Coverage.py measures which lines of Python code are executed during test runs, using standard library tracing to identify executable and covered code paths.

Verdict: Coverage.py is a mature, actively maintained code coverage tool with zero known vulnerabilities, low install friction, and permissive licensing. It is well-suited for integration into test pipelines across modern Python versions.
