Code coverage measurement for Python.

Coverage.py is a tool for measuring code coverage of Python programs. It monitors your program, noting which parts of the code have been executed, then analyzes the source to identify code that could have been executed but was not.

Exclusions

• Excluding code from coverage.py

How to exclude code within the code:

• A line containing a # pragma: no cover comment.
• Or a line containing a # nocov or # noqa comment.
• See exclude_lines in the [report] section of the tox.ini file.
