"""
The Coverage.py integration traces test code coverage when using `pytest` or `unittest`.


Enabling
~~~~~~~~

The Coverage.py integration is enabled automatically when using
:ref:`ddtrace-run<ddtracerun>` or :ref:`import ddtrace.auto<ddtraceauto>`.

Alternately, use :func:`patch()<ddtrace.patch>` to manually enable the integration::

    from ddtrace import patch
    patch(coverage=True)

Note: Coverage.py instrumentation is only enabled if `pytest` or `unittest` instrumentation is enabled.
