==========================
Migrating between versions
==========================
New versions of coverage.py or Python might require you to adjust your
settings, options, or other aspects how you use coverage.py. This page details
those changes.
.. _migrating_cov7:
Migrating to coverage.py 7.x
----------------------------
Consider these changes when migrating to coverage.py 7.x:
- The way that wildcards when specifying file paths work in certain cases has
changed in 7.x:
- Previously, ``*`` would incorrectly match directory separators, making
precise matching difficult. Patterns such as ``*tests/*``
will need to be changed to ``*/tests/*``.
- ``**`` now matches any number of nested directories. If you wish to retain
the behavior of ``**/tests/*`` in previous versions then ``*/**/tests/*``
can be used instead.
- When remapping file paths with ``[paths]``, a path will be remapped only if
the resulting path exists. Ensure that remapped ``[paths]`` exist when
upgrading as this is now being enforced.
- The :ref:`config_report_exclude_also` setting is new in 7.2.0. It adds
exclusion regexes while keeping the default built-in set. It's better than
the older :ref:`config_report_exclude_lines` setting, which overwrote the
entire list. Newer versions of coverage.py will be adding to the default set
of exclusions. Using ``exclude_also`` will let you benefit from those
updates.
.. _migrating_py312:
Migrating to Python 3.12
------------------------
Keep these things in mind when running under Python 3.12:
- Python 3.12 now inlines list, dict, and set comprehensions. Previously, they
were compiled as functions that were called internally. Coverage.py would
warn you if comprehensions weren't fully completed, but this no longer
happens with Python 3.12.
