Changelog

3.7.1

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

Bug Fixes
---------

- `3473 <https://github.com/pytest-dev/pytest/issues/3473>`_: Raise immediately if ``approx()`` is given an expected value of a type it doesn't understand (e.g. strings, nested dicts, etc.).


- `3712 <https://github.com/pytest-dev/pytest/issues/3712>`_: Correctly represent the dimensions of an numpy array when calling ``repr()`` on ``approx()``.

- `3742 <https://github.com/pytest-dev/pytest/issues/3742>`_: Fix incompatibility with third party plugins during collection, which produced the error ``object has no attribute '_collectfile'``.

- `3745 <https://github.com/pytest-dev/pytest/issues/3745>`_: Display the absolute path if ``cache_dir`` is not relative to the ``rootdir`` instead of failing.


- `3747 <https://github.com/pytest-dev/pytest/issues/3747>`_: Fix compatibility problem with plugins and the warning code issued by fixture functions when they are called directly.


- `3748 <https://github.com/pytest-dev/pytest/issues/3748>`_: Fix infinite recursion in ``pytest.approx`` with arrays in ``numpy<1.13``.


- `3757 <https://github.com/pytest-dev/pytest/issues/3757>`_: Pin pathlib2 to ``>=2.2.0`` as we require ``__fspath__`` support.


- `3763 <https://github.com/pytest-dev/pytest/issues/3763>`_: Fix ``TypeError`` when the assertion message is ``bytes`` in python 3.

3.7.0

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

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

- `2639 <https://github.com/pytest-dev/pytest/issues/2639>`_: ``pytest_namespace`` has been deprecated.

See the documentation for ``pytest_namespace`` hook for suggestions on how to deal
with this in plugins which use this functionality.


- `3661 <https://github.com/pytest-dev/pytest/issues/3661>`_: Calling a fixture function directly, as opposed to request them in a test function, now issues a ``RemovedInPytest4Warning``. It will be changed into an error in pytest ``4.0``.

This is a great source of confusion to new users, which will often call the fixture functions and request them from test functions interchangeably, which breaks the fixture resolution model.



Features
--------

- `2283 <https://github.com/pytest-dev/pytest/issues/2283>`_: New ``package`` fixture scope: fixtures are finalized when the last test of a *package* finishes. This feature is considered **experimental**, so use it sparingly.


- `3576 <https://github.com/pytest-dev/pytest/issues/3576>`_: ``Node.add_marker`` now supports an ``append=True/False`` parameter to determine whether the mark comes last (default) or first.


- `3579 <https://github.com/pytest-dev/pytest/issues/3579>`_: Fixture ``caplog`` now has a ``messages`` property, providing convenient access to the format-interpolated log messages without the extra data provided by the formatter/handler.


- `3610 <https://github.com/pytest-dev/pytest/issues/3610>`_: New ``--trace`` option to enter the debugger at the start of a test.


- `3623 <https://github.com/pytest-dev/pytest/issues/3623>`_: Introduce ``pytester.copy_example`` as helper to do acceptance tests against examples from the project.



Bug Fixes
---------

- `2220 <https://github.com/pytest-dev/pytest/issues/2220>`_: Fix a bug where fixtures overridden by direct parameters (for example parametrization) were being instantiated even if they were not being used by a test.


- `3695 <https://github.com/pytest-dev/pytest/issues/3695>`_: Fix ``ApproxNumpy`` initialisation argument mixup, ``abs`` and ``rel`` tolerances were flipped causing strange comparsion results.
Add tests to check ``abs`` and ``rel`` tolerances for ``np.array`` and test for expecting ``nan`` with ``np.array()``


- `980 <https://github.com/pytest-dev/pytest/issues/980>`_: Fix truncated locals output in verbose mode.



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

- `3295 <https://github.com/pytest-dev/pytest/issues/3295>`_: Correct the usage documentation of ``--last-failed-no-failures`` by adding the missing ``--last-failed`` argument in the presented examples, because they are misleading and lead to think that the missing argument is not needed.



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

- `3519 <https://github.com/pytest-dev/pytest/issues/3519>`_: Now a ``README.md`` file is created in ``.pytest_cache`` to make it clear why the directory exists.

3.6.4

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

Bug Fixes
---------

- Invoke pytest using ``-mpytest`` so ``sys.path`` does not get polluted by packages installed in ``site-packages``. (`742 <https://github.com/pytest-dev/pytest/issues/742>`_)


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

- Use ``smtp_connection`` instead of ``smtp`` in fixtures documentation to avoid possible confusion. (`3592 <https://github.com/pytest-dev/pytest/issues/3592>`_)


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

- Remove obsolete ``__future__`` imports. (`2319 <https://github.com/pytest-dev/pytest/issues/2319>`_)

- Add CITATION to provide information on how to formally cite pytest. (`3402 <https://github.com/pytest-dev/pytest/issues/3402>`_)

- Replace broken type annotations with type comments. (`3635 <https://github.com/pytest-dev/pytest/issues/3635>`_)

- Pin ``pluggy`` to ``<0.8``. (`3727 <https://github.com/pytest-dev/pytest/issues/3727>`_)

3.6.3

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

Bug Fixes
---------

- Fix ``ImportWarning`` triggered by explicit relative imports in
assertion-rewritten package modules. (`3061
<https://github.com/pytest-dev/pytest/issues/3061>`_)

- Fix error in ``pytest.approx`` when dealing with 0-dimension numpy
arrays. (`3593 <https://github.com/pytest-dev/pytest/issues/3593>`_)

- No longer raise ``ValueError`` when using the ``get_marker`` API. (`3605
<https://github.com/pytest-dev/pytest/issues/3605>`_)

- Fix problem where log messages with non-ascii characters would not
appear in the output log file.
(`3630 <https://github.com/pytest-dev/pytest/issues/3630>`_)

- No longer raise ``AttributeError`` when legacy marks can't be stored in
functions. (`3631 <https://github.com/pytest-dev/pytest/issues/3631>`_)


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

- The description above the example for ``pytest.mark.skipif`` now better
matches the code. (`3611
<https://github.com/pytest-dev/pytest/issues/3611>`_)


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

- Internal refactoring: removed unused ``CallSpec2tox ._globalid_args``
attribute and ``metafunc`` parameter from ``CallSpec2.copy()``. (`3598
<https://github.com/pytest-dev/pytest/issues/3598>`_)

- Silence usage of ``reduce`` warning in Python 2 (`3609
<https://github.com/pytest-dev/pytest/issues/3609>`_)

- Fix usage of ``attr.ib`` deprecated ``convert`` parameter. (`3653
<https://github.com/pytest-dev/pytest/issues/3653>`_)
