Update pytest to 3.6.0

[pyup-bot]

This PR updates pytest from 3.4.1 to 3.6.0.

Changelog

3.6.0

=========================

Features
--------

- Revamp the internals of the ``pytest.mark`` implementation with correct per
node handling which fixes a number of long standing bugs caused by the old
design. This introduces new ``Node.iter_markers(name)`` and
``Node.get_closest_mark(name)`` APIs. Users are **strongly encouraged** to
read the `reasons for the revamp in the docs
<https://docs.pytest.org/en/latest/mark.htmlmarker-revamp-and-iteration>`_,
or jump over to details about `updating existing code to use the new APIs
<https://docs.pytest.org/en/latest/mark.htmlupdating-code>`_. (`3317
<https://github.com/pytest-dev/pytest/issues/3317>`_)

- Now when ``pytest.fixture`` is applied more than once to the same function a
``ValueError`` is raised. This buggy behavior would cause surprising problems
and if was working for a test suite it was mostly by accident. (`2334
<https://github.com/pytest-dev/pytest/issues/2334>`_)

- Support for Python 3.7's builtin ``breakpoint()`` method, see `Using the
builtin breakpoint function
<https://docs.pytest.org/en/latest/usage.htmlbreakpoint-builtin>`_ for
details. (`3180 <https://github.com/pytest-dev/pytest/issues/3180>`_)

- ``monkeypatch`` now supports a ``context()`` function which acts as a context
manager which undoes all patching done within the ``with`` block. (`3290
<https://github.com/pytest-dev/pytest/issues/3290>`_)

- The ``--pdb`` option now causes KeyboardInterrupt to enter the debugger,
instead of stopping the test session. On python 2.7, hitting CTRL+C again
exits the debugger. On python 3.2 and higher, use CTRL+D. (`3299
<https://github.com/pytest-dev/pytest/issues/3299>`_)

- pytest not longer changes the log level of the root logger when the
``log-level`` parameter has greater numeric value than that of the level of
the root logger, which makes it play better with custom logging configuration
in user code. (`3307 <https://github.com/pytest-dev/pytest/issues/3307>`_)


Bug Fixes
---------

- A rare race-condition which might result in corrupted ``.pyc`` files on
Windows has been hopefully solved. (`3008
<https://github.com/pytest-dev/pytest/issues/3008>`_)

- Also use iter_marker for discovering the marks applying for marker
expressions from the cli to avoid the bad data from the legacy mark storage.
(`3441 <https://github.com/pytest-dev/pytest/issues/3441>`_)

- When showing diffs of failed assertions where the contents contain only
whitespace, escape them using ``repr()`` first to make it easy to spot the
differences. (`3443 <https://github.com/pytest-dev/pytest/issues/3443>`_)


Improved Documentation
----------------------

- Change documentation copyright year to a range which auto-updates itself each
time it is published. (`3303
<https://github.com/pytest-dev/pytest/issues/3303>`_)


Trivial/Internal Changes
------------------------

- ``pytest`` now depends on the `python-atomicwrites
<https://github.com/untitaker/python-atomicwrites>`_ library. (`3008
<https://github.com/pytest-dev/pytest/issues/3008>`_)

- Update all pypi.python.org URLs to pypi.org. (`3431
<https://github.com/pytest-dev/pytest/issues/3431>`_)

- Detect `pytest_` prefixed hooks using the internal plugin manager since
``pluggy`` is deprecating the ``implprefix`` argument to ``PluginManager``.
(`3487 <https://github.com/pytest-dev/pytest/issues/3487>`_)

- Import ``Mapping`` and ``Sequence`` from ``_pytest.compat`` instead of
directly from ``collections`` in ``python_api.py::approx``. Add ``Mapping``
to ``_pytest.compat``, import it from ``collections`` on python 2, but from
``collections.abc`` on Python 3 to avoid a ``DeprecationWarning`` on Python
3.7 or newer. (`3497 <https://github.com/pytest-dev/pytest/issues/3497>`_)

3.5.1

=========================


Bug Fixes
---------

- Reset ``sys.last_type``, ``sys.last_value`` and ``sys.last_traceback`` before
each test executes. Those attributes are added by pytest during the test run
to aid debugging, but were never reset so they would create a leaking
reference to the last failing test's frame which in turn could never be
reclaimed by the garbage collector. (`2798
<https://github.com/pytest-dev/pytest/issues/2798>`_)

- ``pytest.raises`` now raises ``TypeError`` when receiving an unknown keyword
argument. (`3348 <https://github.com/pytest-dev/pytest/issues/3348>`_)

- ``pytest.raises`` now works with exception classes that look like iterables.
(`3372 <https://github.com/pytest-dev/pytest/issues/3372>`_)


Improved Documentation
----------------------

- Fix typo in ``caplog`` fixture documentation, which incorrectly identified
certain attributes as methods. (`3406
<https://github.com/pytest-dev/pytest/issues/3406>`_)


Trivial/Internal Changes
------------------------

- Added a more indicative error message when parametrizing a function whose
argument takes a default value. (`3221
<https://github.com/pytest-dev/pytest/issues/3221>`_)

- Remove internal ``_pytest.terminal.flatten`` function in favor of
``more_itertools.collapse``. (`3330
<https://github.com/pytest-dev/pytest/issues/3330>`_)

- Import some modules from ``collections.abc`` instead of ``collections`` as
the former modules trigger ``DeprecationWarning`` in Python 3.7. (`3339
<https://github.com/pytest-dev/pytest/issues/3339>`_)

- record_property is no longer experimental, removing the warnings was
forgotten. (`3360 <https://github.com/pytest-dev/pytest/issues/3360>`_)

- Mention in documentation and CLI help that fixtures with leading ``_`` are
printed by ``pytest --fixtures`` only if the ``-v`` option is added. (`3398
<https://github.com/pytest-dev/pytest/issues/3398>`_)

3.5.0

=========================

Deprecations and Removals
-------------------------

- ``record_xml_property`` fixture is now deprecated in favor of the more
generic ``record_property``. (`2770
<https://github.com/pytest-dev/pytest/issues/2770>`_)

- Defining ``pytest_plugins`` is now deprecated in non-top-level conftest.py
files, because they "leak" to the entire directory tree. (`3084
<https://github.com/pytest-dev/pytest/issues/3084>`_)


Features
--------

- New ``--show-capture`` command-line option that allows to specify how to
display captured output when tests fail: ``no``, ``stdout``, ``stderr``,
``log`` or ``all`` (the default). (`1478
<https://github.com/pytest-dev/pytest/issues/1478>`_)

- New ``--rootdir`` command-line option to override the rules for discovering
the root directory. See `customize
<https://docs.pytest.org/en/latest/customize.html>`_ in the documentation for
details. (`1642 <https://github.com/pytest-dev/pytest/issues/1642>`_)

- Fixtures are now instantiated based on their scopes, with higher-scoped
fixtures (such as ``session``) being instantiated first than lower-scoped
fixtures (such as ``function``). The relative order of fixtures of the same
scope is kept unchanged, based in their declaration order and their
dependencies. (`2405 <https://github.com/pytest-dev/pytest/issues/2405>`_)

- ``record_xml_property`` renamed to ``record_property`` and is now compatible
with xdist, markers and any reporter. ``record_xml_property`` name is now
deprecated. (`2770 <https://github.com/pytest-dev/pytest/issues/2770>`_)

- New ``--nf``, ``--new-first`` options: run new tests first followed by the
rest of the tests, in both cases tests are also sorted by the file modified
time, with more recent files coming first. (`3034
<https://github.com/pytest-dev/pytest/issues/3034>`_)

- New ``--last-failed-no-failures`` command-line option that allows to specify
the behavior of the cache plugin's --last-failed`` feature when no tests
failed in the last run (or no cache was found): ``none`` or ``all`` (the
default). (`3139 <https://github.com/pytest-dev/pytest/issues/3139>`_)

- New ``--doctest-continue-on-failure`` command-line option to enable doctests
to show multiple failures for each snippet, instead of stopping at the first
failure. (`3149 <https://github.com/pytest-dev/pytest/issues/3149>`_)

- Captured log messages are added to the ``<system-out>`` tag in the generated
junit xml file if the ``junit_logging`` ini option is set to ``system-out``.
If the value of this ini option is ``system-err``, the logs are written to
``<system-err>``. The default value for ``junit_logging`` is ``no``, meaning
captured logs are not written to the output file. (`3156
<https://github.com/pytest-dev/pytest/issues/3156>`_)

- Allow the logging plugin to handle ``pytest_runtest_logstart`` and
``pytest_runtest_logfinish`` hooks when live logs are enabled. (`3189
<https://github.com/pytest-dev/pytest/issues/3189>`_)

- Passing `--log-cli-level` in the command-line now automatically activates
live logging. (`3190 <https://github.com/pytest-dev/pytest/issues/3190>`_)

- Add command line option ``--deselect`` to allow deselection of individual
tests at collection time. (`3198
<https://github.com/pytest-dev/pytest/issues/3198>`_)

- Captured logs are printed before entering pdb. (`3204
<https://github.com/pytest-dev/pytest/issues/3204>`_)

- Deselected item count is now shown before tests are run, e.g. ``collected X
items / Y deselected``. (`3213
<https://github.com/pytest-dev/pytest/issues/3213>`_)

- The builtin module ``platform`` is now available for use in expressions in
``pytest.mark``. (`3236
<https://github.com/pytest-dev/pytest/issues/3236>`_)

- The *short test summary info* section now is displayed after tracebacks and
warnings in the terminal. (`3255
<https://github.com/pytest-dev/pytest/issues/3255>`_)

- New ``--verbosity`` flag to set verbosity level explicitly. (`3296
<https://github.com/pytest-dev/pytest/issues/3296>`_)

- ``pytest.approx`` now accepts comparing a numpy array with a scalar. (`3312
<https://github.com/pytest-dev/pytest/issues/3312>`_)


Bug Fixes
---------

- Suppress ``IOError`` when closing the temporary file used for capturing
streams in Python 2.7. (`2370
<https://github.com/pytest-dev/pytest/issues/2370>`_)

- Fixed ``clear()`` method on ``caplog`` fixture which cleared ``records``, but
not the ``text`` property. (`3297
<https://github.com/pytest-dev/pytest/issues/3297>`_)

- During test collection, when stdin is not allowed to be read, the
``DontReadFromStdin`` object still allow itself to be iterable and resolved
to an iterator without crashing. (`3314
<https://github.com/pytest-dev/pytest/issues/3314>`_)


Improved Documentation
----------------------

- Added a `reference <https://docs.pytest.org/en/latest/reference.html>`_ page
to the docs. (`1713 <https://github.com/pytest-dev/pytest/issues/1713>`_)


Trivial/Internal Changes
------------------------

- Change minimum requirement of ``attrs`` to ``17.4.0``. (`3228
<https://github.com/pytest-dev/pytest/issues/3228>`_)

- Renamed example directories so all tests pass when ran from the base
directory. (`3245 <https://github.com/pytest-dev/pytest/issues/3245>`_)

- Internal ``mark.py`` module has been turned into a package. (`3250
<https://github.com/pytest-dev/pytest/issues/3250>`_)

- ``pytest`` now depends on the `more-itertools
<https://github.com/erikrose/more-itertools>`_ package. (`3265
<https://github.com/pytest-dev/pytest/issues/3265>`_)

- Added warning when ``[pytest]`` section is used in a ``.cfg`` file passed
with ``-c`` (`3268 <https://github.com/pytest-dev/pytest/issues/3268>`_)

- ``nodeids`` can now be passed explicitly to ``FSCollector`` and ``Node``
constructors. (`3291 <https://github.com/pytest-dev/pytest/issues/3291>`_)

- Internal refactoring of ``FormattedExcinfo`` to use ``attrs`` facilities and
remove old support code for legacy Python versions. (`3292
<https://github.com/pytest-dev/pytest/issues/3292>`_)

- Refactoring to unify how verbosity is handled internally. (`3296
<https://github.com/pytest-dev/pytest/issues/3296>`_)

- Internal refactoring to better integrate with argparse. (`3304
<https://github.com/pytest-dev/pytest/issues/3304>`_)
