Update to 2.7.0:

2.7.0 (compared to 2.6.4)
-----------------------------

- fix issue435: make reload() work when assert rewriting is active.
  Thanks Daniel Hahler.

- fix issue616: conftest.py files and their contained fixutres are now
  properly considered for visibility, independently from the exact
  current working directory and test arguments that are used.
  Many thanks to Eric Siegerman and his PR235 which contains
  systematic tests for conftest visibility and now passes.
  This change also introduces the concept of a ``rootdir`` which
  is printed as a new pytest header and documented in the pytest
  customize web page.

- change reporting of "diverted" tests, i.e. tests that are collected
  in one file but actually come from another (e.g. when tests in a test class
  come from a base class in a different file).  We now show the nodeid
  and indicate via a postfix the other file.

- add ability to set command line options by environment variable PYTEST_ADDOPTS.

- added documentation on the new pytest-dev teams on bitbucket and
  github.  See https://pytest.org/latest/contributing.html .
  Thanks to Anatoly for pushing and initial work on this.

- fix issue650: new option ``--docttest-ignore-import-errors`` which
  will turn import errors in doctests into skips.  Thanks Charles Cloud
  for the complete PR.

- fix issue655: work around different ways that cause python2/3
  to leak sys.exc_info into fixtures/tests causing failures in 3rd party code

- fix issue615: assertion re-writing did not correctly escape % signs
  when formatting boolean operations, which tripped over mixing
  booleans with modulo operators.  Thanks to Tom Viner for the report,
  triaging and fix.

- implement issue351: add ability to specify parametrize ids as a callable
  to generate custom test ids.  Thanks Brianna Laugher for the idea and
  implementation.

- introduce and document new hookwrapper mechanism useful for plugins
  which want to wrap the execution of certain hooks for their purposes.
  This supersedes the undocumented ``__multicall__`` protocol which
  pytest itself and some external plugins use.  Note that pytest-2.8
  is scheduled to drop supporting the old ``__multicall__``
  and only support the hookwrapper protocol.

- majorly speed up invocation of plugin hooks

- use hookwrapper mechanism in builtin pytest plugins.

- add a doctest ini option for doctest flags, thanks Holger Peters.

- add note to docs that if you want to mark a parameter and the
  parameter is a callable, you also need to pass in a reason to disambiguate
  it from the "decorator" case.  Thanks Tom Viner.

- "python_classes" and "python_functions" options now \ 
support glob-patterns
 for test discovery, as discussed in issue600. Thanks Ldiary Translations.

- allow to override parametrized fixtures with non-parametrized ones and vice \ 
versa (bubenkoff).

- fix issue463: raise specific error for 'parameterize' misspelling (pfctdayelise).

- On failure, the ``sys.last_value``, ``sys.last_type`` and
  ``sys.last_traceback`` are set, so that a user can inspect the error
  via postmortem debugging (almarklein).

Update to 2.6.4:

2.6.4
----------

- Improve assertion failure reporting on iterables, by using ndiff and pprint.

- removed outdated japanese docs from source tree.

- docs for "pytest_addhooks" hook.  Thanks Bruno Oliveira.

- updated plugin index docs.  Thanks Bruno Oliveira.

- fix issue557: with "-k" we only allow the old style "-" \ 
for negation
  at the beginning of strings and even that is deprecated.  Use "not" \ 
instead.
  This should allow to pick parametrized tests where "-" appeared in \ 
the parameter.

- fix issue604: Escape % character in the assertion message.

- fix issue620: add explanation in the --genscript target about what
  the binary blob means. Thanks Dinu Gherman.

  instead of errors, thanks Oleg Sinyavskiy.

- fix issue582: fix setuptools example, thanks Laszlo Papp and Ronny
  Pfannschmidt.

- Fix infinite recursion bug when pickling capture.EncodedFile, thanks
  Uwe Schmitt.

- fix issue589: fix bad interaction with numpy and others when showing
  exceptions.  Check for precise "maximum recursion depth exceed" exception
  instead of presuming any RuntimeError is that one (implemented in py
  dep).  Thanks Charles Cloud for analysing the issue.

- fix conftest related fixture visibility issue: when running with a
  CWD outside a test package pytest would get fixture discovery wrong.
  Thanks to Wolfgang Schnerring for figuring out a reproducable example.

- Introduce pytest_enter_pdb hook (needed e.g. by pytest_timeout to cancel the
  timeout when interactively entering pdb).  Thanks Wolfgang Schnerring.

- check xfail/skip also with non-python function test items. Thanks
  Floris Bruynooghe.

Log message:
Update to 2.6.2:

2.6.2

- fixed issue561: adapt autouse fixture example for python3.

- fixed issue453: assertion rewriting issue with __repr__ containing
  "\n{", "\n}" and "\n~".

- fix issue560: correctly display code if an "else:" or \ 
"finally:" is
  followed by statements on the same line.

- Fix example in monkeypatch documentation, thanks t-8ch.

- fix issue572: correct tmpdir doc example for python3.

- Do not mark as universal wheel because Python 2.6 is different from
  other builds due to the extra argparse dependency.  Fixes issue566.
  Thanks sontek.

Log message:
Update to 2.6.1:

2.6.1
-----------------------------------

- No longer show line numbers in the --verbose output, the output is now
  purely the nodeid.  The line number is still shown in failure reports.
  Thanks Floris Bruynooghe.

- fix issue437 where assertion rewriting could cause pytest-xdist slaves
  to collect different tests. Thanks Bruno Oliveira.

- fix issue555: add "errors" attribute to capture-streams to satisfy
  some distutils and possibly other code accessing sys.stdout.errors.

- fix issue547 capsys/capfd also work when output capturing ("-s") is \ 
disabled.

- address issue170: allow pytest.mark.xfail(...) to specify expected exceptions via
  an optional "raises=EXC" argument where EXC can be a single exception
  or a tuple of exception classes.  Thanks David Mohr for the complete
  PR.

- fix integration of pytest with unittest.mock.patch decorator when
  it uses the "new" argument.  Thanks Nicolas Delaby for test and PR.

- fix issue with detecting conftest files if the arguments contain
  "::" node id specifications (copy pasted from "-v" output)

- fix issue544 by only removing "@NUM" at the end of "::" \ 
separated parts
  and if the part has an ".py" extension

- don't use py.std import helper, rather import things directly.
  Thanks Bruno Oliveira.

Log message:
Update to 2.6.0:

NEXT (2.6)
-----------------------------------

- Cache exceptions from fixtures according to their scope (issue 467).

- fix issue537: Avoid importing old assertion reinterpretation code by default.

- fix issue364: shorten and enhance tracebacks representation by default.
  The new "--tb=auto" option (default) will only display long tracebacks
  for the first and last entry.  You can get the old behaviour of printing
  all entries as long entries with "--tb=long".  Also short entries by
  default are now printed very similarly to "--tb=native" ones.

- fix issue514: teach assertion reinterpretation about private class attributes

- change -v output to include full node IDs of tests.  Users can copy
  a node ID from a test run, including line number, and use it as a
  positional argument in order to run only a single test.

- fix issue 475: fail early and comprehensible if calling
  pytest.raises with wrong exception type.

- fix issue516: tell in getting-started about current dependencies.

- cleanup setup.py a bit and specify supported versions. Thanks Jurko
  Gospodnetic for the PR.

- change XPASS colour to yellow rather then red when tests are run
  with -v.

- fix issue473: work around mock putting an unbound method into a class
  dict when double-patching.

- fix issue498: if a fixture finalizer fails, make sure that
  the fixture is still invalidated.

- fix issue453: the result of the pytest_assertrepr_compare hook now gets
  it's newlines escaped so that format_exception does not blow up.

- internal new warning system: pytest will now produce warnings when
  it detects oddities in your test collection or execution.
  Warnings are ultimately sent to a new pytest_logwarning hook which is
  currently only implemented by the terminal plugin which displays
  warnings in the summary line and shows more details when -rw (report on
  warnings) is specified.

- change skips into warnings for test classes with an __init__ and
  callables in test modules which look like a test but are not functions.

- fix issue436: improved finding of initial conftest files from command
  line arguments by using the result of parse_known_args rather than
  the previous flaky heuristics.  Thanks Marc Abramowitz for tests
  and initial fixing approaches in this area.

- fix issue #479: properly handle nose/unittest(2) SkipTest exceptions
  during collection/loading of test modules.  Thanks to Marc Schlaich
  for the complete PR.

- fix issue490: include pytest_load_initial_conftests in documentation
  and improve docstring.

- fix issue472: clarify that ``pytest.config.getvalue()`` cannot work
  if it's triggered ahead of command line parsing.

- merge PR123: improved integration with mock.patch decorator on tests.

- fix issue412: messing with stdout/stderr FD-level streams is now
  captured without crashes.

- fix issue483: trial/py33 works now properly.  Thanks Daniel Grana for PR.

- improve example for pytest integration with "python setup.py test"
  which now has a generic "-a" or "--pytest-args" option \ 
where you
  can pass additional options as a quoted string.  Thanks Trevor Bekolay.

- simplified internal capturing mechanism and made it more robust
  against tests or setups changing FD1/FD2, also better integrated
  now with pytest.pdb() in single tests.

- improvements to pytest's own test-suite leakage detection, courtesy of PRs
  from Marc Abramowitz

- fix issue492: avoid leak in test_writeorg.  Thanks Marc Abramowitz.

- fix issue493: don't run tests in doc directory with ``python setup.py test``
  (use tox -e doctesting for that)

- fix issue486: better reporting and handling of early conftest loading failures

- some cleanup and simplification of internal conftest handling.

- work a bit harder to break reference cycles when catching exceptions.
  Thanks Jurko Gospodnetic.

- fix issue443: fix skip examples to use proper comparison.  Thanks Alex
  Groenholm.

- support nose-style ``__test__`` attribute on modules, classes and
  functions, including unittest-style Classes.  If set to False, the
  test will not be collected.

- fix issue512: show "<notset>" for arguments which might not be set
  in monkeypatch plugin.  Improves output in documentation.

Depend on py-1.4.20. Bump PKGREVISION.

Log message:
Update to 2.5.2 (leaf package).
Add missing dependencies. Add test dependencies. Replace interpreter
path in installed file.

Changes since 2.3.5:

2.5.2
-----------------------------------

- fix issue409 -- better interoperate with cx_freeze by not
  trying to import from collections.abc which causes problems
  for py27/cx_freeze.  Thanks Wolfgang L. for reporting and tracking it down.

- fixed docs and code to use "pytest" instead of "py.test" \ 
almost everywhere.
  Thanks Jurko Gospodnetic for the complete PR.

- fix issue425: mention at end of "py.test -h" that --markers
  and --fixtures work according to specified test path (or current dir)

- fix issue413: exceptions with unicode attributes are now printed
  correctly also on python2 and with pytest-xdist runs. (the fix
  requires py-1.4.20)

- copy, cleanup and integrate py.io capture
  from pylib 1.4.20.dev2 (rev 13d9af95547e)

- address issue416: clarify docs as to conftest.py loading semantics

- fix issue429: comparing byte strings with non-ascii chars in assert
  expressions now work better.  Thanks Floris Bruynooghe.

- make capfd/capsys.capture private, its unused and shouldnt be exposed

2.5.1
-----------------------------------

- merge new documentation styling PR from Tobias Bieniek.

- fix issue403: allow parametrize of multiple same-name functions within
  a collection node.  Thanks Andreas Kloeckner and Alex Gaynor for reporting
  and analysis.

- Allow parameterized fixtures to specify the ID of the parameters by
  adding an ids argument to pytest.fixture() and pytest.yield_fixture().
  Thanks Floris Bruynooghe.

- fix issue404 by always using the binary xml escape in the junitxml
  plugin.  Thanks Ronny Pfannschmidt.

- fix issue407: fix addoption docstring to point to argparse instead of
  optparse. Thanks Daniel D. Wright.

2.5.0
-----------------------------------

- dropped python2.5 from automated release testing of pytest itself
  which means it's probably going to break soon (but still works
  with this release we believe).

- simplified and fixed implementation for calling finalizers when
  parametrized fixtures or function arguments are involved.  finalization
  is now performed lazily at setup time instead of in the "teardown phase".
  While this might sound odd at first, it helps to ensure that we are
  correctly handling setup/teardown even in complex code.  User-level code
  should not be affected unless it's implementing the pytest_runtest_teardown
  hook and expecting certain fixture instances are torn down within (very
  unlikely and would have been unreliable anyway).

- PR90: add --color=yes|no|auto option to force terminal coloring
  mode ("auto" is default).  Thanks Marc Abramowitz.

- fix issue319 - correctly show unicode in assertion errors.  Many
  thanks to Floris Bruynooghe for the complete PR.  Also means
  we depend on py>=1.4.19 now.

- fix issue396 - correctly sort and finalize class-scoped parametrized
  tests independently from number of methods on the class.

- refix issue323 in a better way -- parametrization should now never
  cause Runtime Recursion errors because the underlying algorithm
  for re-ordering tests per-scope/per-fixture is not recursive
  anymore (it was tail-call recursive before which could lead
  to problems for more than >966 non-function scoped parameters).

- fix issue290 - there is preliminary support now for parametrizing
  with repeated same values (sometimes useful to to test if calling
  a second time works as with the first time).

- close issue240 - document precisely how pytest module importing
  works, discuss the two common test directory layouts, and how it
  interacts with PEP420-namespace packages.

- fix issue246 fix finalizer order to be LIFO on independent fixtures
  depending on a parametrized higher-than-function scoped fixture.
  (was quite some effort so please bear with the complexity of this sentence :)
  Thanks Ralph Schmitt for the precise failure example.

- fix issue244 by implementing special index for parameters to only use
  indices for paramentrized test ids

- fix issue287 by running all finalizers but saving the exception
  from the first failing finalizer and re-raising it so teardown will
  still have failed.  We reraise the first failing exception because
  it might be the cause for other finalizers to fail.

- fix ordering when mock.patch or other standard decorator-wrappings
  are used with test methods.  This fixues issue346 and should
  help with random "xdist" collection failures.  Thanks to
  Ronny Pfannschmidt and Donald Stufft for helping to isolate it.

- fix issue357 - special case "-k" expressions to allow for
  filtering with simple strings that are not valid python expressions.
  Examples: "-k 1.3" matches all tests parametrized with 1.3.
  "-k None" filters all tests that have "None" in their name
  and conversely "-k 'not None'".
  Previously these examples would raise syntax errors.

- fix issue384 by removing the trial support code
  since the unittest compat enhancements allow
  trial to handle it on its own

- don't hide an ImportError when importing a plugin produces one.
  fixes issue375.

- fix issue275 - allow usefixtures and autouse fixtures
  for running doctest text files.

- fix issue380 by making --resultlog only rely on longrepr instead
  of the "reprcrash" attribute which only exists sometimes.

- address issue122: allow @pytest.fixture(params=iterator) by exploding
  into a list early on.

- fix pexpect-3.0 compatibility for pytest's own tests.
  (fixes issue386)

- allow nested parametrize-value markers, thanks James Lan for the PR.

- fix unicode handling with new monkeypatch.setattr(import_path, value)
  API.  Thanks Rob Dennis.  Fixes issue371.

- fix unicode handling with junitxml, fixes issue368.

- In assertion rewriting mode on Python 2, fix the detection of coding
  cookies. See issue #330.

- make "--runxfail" turn imperative pytest.xfail calls into no ops
  (it already did neutralize pytest.mark.xfail markers)

- refine pytest / pkg_resources interactions: The AssertionRewritingHook
  PEP302 compliant loader now registers itself with setuptools/pkg_resources
  properly so that the pkg_resources.resource_stream method works properly.
  Fixes issue366.  Thanks for the investigations and full PR to Jason R. Coombs.

- pytestconfig fixture is now session-scoped as it is the same object during the
  whole test run.  Fixes issue370.

- avoid one surprising case of marker malfunction/confusion::

      @pytest.mark.some(lambda arg: ...)
      def test_function():

  would not work correctly because pytest assumes @pytest.mark.some
  gets a function to be decorated already.  We now at least detect if this
  arg is an lambda and thus the example will work.  Thanks Alex Gaynor
  for bringing it up.

- xfail a test on pypy that checks wrong encoding/ascii (pypy does
  not error out). fixes issue385.

- internally make varnames() deal with classes's __init__,
  although it's not needed by pytest itself atm.  Also
  fix caching.  Fixes issue376.

- fix issue221 - handle importing of namespace-package with no
  __init__.py properly.

- refactor internal FixtureRequest handling to avoid monkeypatching.
  One of the positive user-facing effects is that the "request" object
  can now be used in closures.

- fixed version comparison in pytest.importskip(modname, minverstring)

- fix issue377 by clarifying in the nose-compat docs that pytest
  does not duplicate the unittest-API into the "plain" namespace.

- fix verbose reporting for @mock'd test functions

v2.4.2
-----------------------------------

- on Windows require colorama and a newer py lib so that py.io.TerminalWriter()
  now uses colorama instead of its own ctypes hacks. (fixes issue365)
  thanks Paul Moore for bringing it up.

- fix "-k" matching of tests where "repr" and \ 
"attr" and other names would
  cause wrong matches because of an internal implementation quirk
  (don't ask) which is now properly implemented. fixes issue345.

- avoid tmpdir fixture to create too long filenames especially
  when parametrization is used (issue354)

- fix pytest-pep8 and pytest-flakes / pytest interactions
  (collection names in mark plugin was assuming an item always
  has a function which is not true for those plugins etc.)
  Thanks Andi Zeidler.

- introduce node.get_marker/node.add_marker API for plugins
  like pytest-pep8 and pytest-flakes to avoid the messy
  details of the node.keywords  pseudo-dicts.  Adapated
  docs.

- remove attempt to "dup" stdout at startup as it's icky.
  the normal capturing should catch enough possibilities
  of tests messing up standard FDs.

- add pluginmanager.do_configure(config) as a link to
  config.do_configure() for plugin-compatibility

v2.4.1
-----------------------------------

- When using parser.addoption() unicode arguments to the
  "type" keyword should also be converted to the respective types.
  thanks Floris Bruynooghe, @dnozay. (fixes issue360 and issue362)

- fix dotted filename completion when using argcomplete
  thanks Anthon van der Neuth. (fixes issue361)

- fix regression when a 1-tuple ("arg",) is used for specifying
  parametrization (the values of the parametrization were passed
  nested in a tuple).  Thanks Donald Stufft.

- merge doc typo fixes, thanks Andy Dirnberger

v2.4
-----------------------------------

known incompatibilities:

- if calling --genscript from python2.7 or above, you only get a
  standalone script which works on python2.7 or above.  Use Python2.6
  to also get a python2.5 compatible version.

- all xunit-style teardown methods (nose-style, pytest-style,
  unittest-style) will not be called if the corresponding setup method failed,
  see issue322 below.

- the pytest_plugin_unregister hook wasn't ever properly called
  and there is no known implementation of the hook - so it got removed.

- pytest.fixture-decorated functions cannot be generators (i.e. use
  yield) anymore.  This change might be reversed in 2.4.1 if it causes
  unforeseen real-life issues.  However, you can always write and return
  an inner function/generator and change the fixture consumer to iterate
  over the returned generator.  This change was done in lieu of the new
  ``pytest.yield_fixture`` decorator, see below.

new features:

- experimentally introduce a new ``pytest.yield_fixture`` decorator
  which accepts exactly the same parameters as pytest.fixture but
  mandates a ``yield`` statement instead of a ``return statement`` from
  fixture functions.  This allows direct integration with "with-style"
  context managers in fixture functions and generally avoids registering
  of finalization callbacks in favour of treating the "after-yield" as
  teardown code.  Thanks Andreas Pelme, Vladimir Keleshev, Floris
  Bruynooghe, Ronny Pfannschmidt and many others for discussions.

- allow boolean expression directly with skipif/xfail
  if a "reason" is also specified.  Rework skipping documentation
  to recommend "condition as booleans" because it prevents surprises
  when importing markers between modules.  Specifying conditions
  as strings will remain fully supported.

- reporting: color the last line red or green depending if
  failures/errors occured or everything passed.  thanks Christian
  Theunert.

- make "import pdb ; pdb.set_trace()" work natively wrt capturing (no
  "-s" needed anymore), making ``pytest.set_trace()`` a mere shortcut.

- fix issue181: --pdb now also works on collect errors (and
  on internal errors) .  This was implemented by a slight internal
  refactoring and the introduction of a new hook
  ``pytest_exception_interact`` hook (see next item).

- fix issue341: introduce new experimental hook for IDEs/terminals to
  intercept debugging: ``pytest_exception_interact(node, call, report)``.

- new monkeypatch.setattr() variant to provide a shorter
  invocation for patching out classes/functions from modules:

     monkeypatch.setattr("requests.get", myfunc)

  will replace the "get" function of the "requests" module \ 
with ``myfunc``.

- fix issue322: tearDownClass is not run if setUpClass failed. Thanks
  Mathieu Agopian for the initial fix.  Also make all of pytest/nose
  finalizer mimick the same generic behaviour: if a setupX exists and
  fails, don't run teardownX.  This internally introduces a new method
  "node.addfinalizer()" helper which can only be called during the setup
  phase of a node.

- simplify pytest.mark.parametrize() signature: allow to pass a
  CSV-separated string to specify argnames.  For example:
  ``pytest.mark.parametrize("input,expected",  [(1,2), (2,3)])``
  works as well as the previous:
  ``pytest.mark.parametrize(("input", "expected"), ...)``.

- add support for setUpModule/tearDownModule detection, thanks Brian Okken.

- integrate tab-completion on options through use of "argcomplete".
  Thanks Anthon van der Neut for the PR.

- change option names to be hyphen-separated long options but keep the
  old spelling backward compatible.  py.test -h will only show the
  hyphenated version, for example "--collect-only" but \ 
"--collectonly"
  will remain valid as well (for backward-compat reasons).  Many thanks to
  Anthon van der Neut for the implementation and to Hynek Schlawack for
  pushing us.

- fix issue 308 - allow to mark/xfail/skip individual parameter sets
  when parametrizing.  Thanks Brianna Laugher.

- call new experimental pytest_load_initial_conftests hook to allow
  3rd party plugins to do something before a conftest is loaded.

Bug fixes:

- fix issue358 - capturing options are now parsed more properly
  by using a new parser.parse_known_args method.

- pytest now uses argparse instead of optparse (thanks Anthon) which
  means that "argparse" is added as a dependency if installing into \ 
python2.6
  environments or below.

- fix issue333: fix a case of bad unittest/pytest hook interaction.

- PR27: correctly handle nose.SkipTest during collection.  Thanks
  Antonio Cuni, Ronny Pfannschmidt.

- fix issue355: junitxml puts name="pytest" attribute to testsuite tag.

- fix issue336: autouse fixture in plugins should work again.

- fix issue279: improve object comparisons on assertion failure
  for standard datatypes and recognise collections.abc.  Thanks to
  Brianna Laugher and Mathieu Agopian.

- fix issue317: assertion rewriter support for the is_package method

- fix issue335: document py.code.ExceptionInfo() object returned
  from pytest.raises(), thanks Mathieu Agopian.

- remove implicit distribute_setup support from setup.py.

- fix issue305: ignore any problems when writing pyc files.

- SO-17664702: call fixture finalizers even if the fixture function
  partially failed (finalizers would not always be called before)

- fix issue320 - fix class scope for fixtures when mixed with
  module-level functions.  Thanks Anatloy Bubenkoff.

- you can specify "-q" or "-qq" to get different levels of \ 
"quieter"
  reporting (thanks Katarzyna Jachim)

- fix issue300 - Fix order of conftest loading when starting py.test
  in a subdirectory.

- fix issue323 - sorting of many module-scoped arg parametrizations

- make sessionfinish hooks execute with the same cwd-context as at
  session start (helps fix plugin behaviour which write output files
  with relative path such as pytest-cov)

- fix issue316 - properly reference collection hooks in docs

- fix issue 306 - cleanup of -k/-m options to only match markers/test
  names/keywords respectively.  Thanks Wouter van Ackooy.

- improved doctest counting for doctests in python modules --
  files without any doctest items will not show up anymore
  and doctest examples are counted as separate test items.
  thanks Danilo Bellini.

- fix issue245 by depending on the released py-1.4.14
  which fixes py.io.dupfile to work with files with no
  mode. Thanks Jason R. Coombs.

- fix junitxml generation when test output contains control characters,
  addressing issue267, thanks Jaap Broekhuizen

- fix issue338: honor --tb style for setup/teardown errors as well.  Thanks Maho.

- fix issue307 - use yaml.safe_load in example, thanks Mark Eichin.

- better parametrize error messages, thanks Brianna Laugher

- pytest_terminal_summary(terminalreporter) hooks can now use
  ".section(title)" and ".line(msg)" methods to print extra
  information at the end of a test run.
