Log Message:
Updated py-test to 3.0.5.

3.0.5
=====

* Add warning when not passing ``option=value`` correctly to \ 
``-o/--override-ini`` (`#2105`_).
  Also improved the help documentation. Thanks to `@mbukatov`_ for the report and
  `@lwm`_ for the PR.

* Now ``--confcutdir`` and ``--junit-xml`` are properly validated if they are \ 
directories
  and filenames, respectively (`#2089`_ and `#2078`_). Thanks to `@lwm`_ for the PR.

* Add hint to error message hinting possible missing ``__init__.py`` (`#478`_). \ 
Thanks `@DuncanBetts`_.

* More accurately describe when fixture finalization occurs in documentation \ 
(`#687`_). Thanks `@DuncanBetts`_.

* Provide ``:ref:`` targets for ``recwarn.rst`` so we can use intersphinx \ 
referencing.
  Thanks to `@dupuy`_ for the report and `@lwm`_ for the PR.

* In Python 2, use a simple ``+-`` ASCII string in the string representation of \ 
``pytest.approx`` (for example ``"4 +- 4.0e-06"``)
  because it is brittle to handle that in different contexts and representations \ 
internally in pytest
  which can result in bugs such as `#2111`_. In Python 3, the representation \ 
still uses ``±`` (for example ``4 ± 4.0e-06``).
  Thanks `@kerrick-lyft`_ for the report and `@nicoddemus`_ for the PR.

* Using ``item.Function``, ``item.Module``, etc., is now issuing deprecation \ 
warnings, prefer
  ``pytest.Function``, ``pytest.Module``, etc., instead (`#2034`_).
  Thanks `@nmundar`_ for the PR.

* Fix error message using ``approx`` with complex numbers (`#2082`_).
  Thanks `@adler-j`_ for the report and `@nicoddemus`_ for the PR.

* Fixed false-positives warnings from assertion rewrite hook for modules \ 
imported more than
  once by the ``pytest_plugins`` mechanism.
  Thanks `@nicoddemus`_ for the PR.

* Remove an internal cache which could cause hooks from ``conftest.py`` files in
  sub-directories to be called in other directories incorrectly (`#2016`_).
  Thanks `@d-b-w`_ for the report and `@nicoddemus`_ for the PR.

* Remove internal code meant to support earlier Python 3 versions that produced \ 
the side effect
  of leaving ``None`` in ``sys.modules`` when expressions were evaluated by \ 
pytest (for example passing a condition
  as a string to ``pytest.mark.skipif``)(`#2103`_).
  Thanks `@jaraco`_ for the report and `@nicoddemus`_ for the PR.

* Cope gracefully with a .pyc file with no matching .py file (`#2038`_). Thanks
  `@nedbat`_.
