deprecated but still present. Thanks to `@RedBeardCode`_ and `@tomviner`_
for PR (`#1626`_).
* Refined logic for determining the ``rootdir``, considering only valid
paths which fixes a number of issues: `#1594`_, `#1435`_ and `#1471`_.
Thanks to `@blueyed`_ and `@davehunt`_ for the PR.
* Always include full assertion explanation. The previous behaviour was hiding
sub-expressions that happened to be False, assuming this was redundant information.
Thanks `@bagerard`_ for reporting (`#1503`_). Thanks to `@davehunt`_ and

Here is the algorithm which finds the rootdir from ``args``:
- determine the common ancestor directory for the specified ``args``.
- determine the common ancestor directory for the specified ``args`` that are
recognised as paths that exist in the file system. If no such paths are
found, the common ancestor directory is set to the current working directory.
- look for ``pytest.ini``, ``tox.ini`` and ``setup.cfg`` files in the
ancestor directory and upwards. If one is matched, it becomes the
ini-file and its directory becomes the rootdir. An existing
``pytest.ini`` file will always be considered a match whereas
``tox.ini`` and ``setup.cfg`` will only match if they contain
a ``[pytest]`` section.

- if no ini-file was found, look for ``setup.py`` upwards from
the common ancestor directory to determine the ``rootdir``.
- if no ini-file was found, look for ``setup.py`` upwards from the common
ancestor directory to determine the ``rootdir``.
- if no ini-file and no ``setup.py`` was found, use the already
determined common ancestor as root directory. This allows to
work with pytest in structures that are not part of a package
and don't have any particular ini-file configuration.
