Pin pytest to latest version 3.1.2

[pyup-bot]

pytest is not pinned to a specific version.

I'm pinning it to the latest version 3.1.2 for now.

Changelog

3.1.2

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

Bug Fixes

• Required options added via pytest_addoption will no longer prevent using
  --help without passing them. (1999)

• Respect python_files in assertion rewriting. (2121)

• Fix recursion error detection when frames in the traceback contain objects
  that can't be compared (like numpy arrays). (2459)

• UnicodeWarning is issued from the internal pytest warnings plugin only
  when the message contains non-ascii unicode (Python 2 only). (2463)

• Added a workaround for Python 3.6 WindowsConsoleIO breaking due to Pytests's
  FDCapture. Other code using console handles might still be affected by the
  very same issue and might require further workarounds/fixes, i.e. colorama.
  (2467)

Improved Documentation

• Fix internal API links to pluggy objects. (2331)

• Make it clear that pytest.xfail stops test execution at the calling point
  and improve overall flow of the skipping docs. (810)

3.1.1

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

Bug Fixes

• pytest warning capture no longer overrides existing warning filters. The
  previous behaviour would override all filters and caused regressions in test
  suites which configure warning filters to match their needs. Note that as a
  side-effect of this is that DeprecationWarning and
  PendingDeprecationWarning are no longer shown by default. (2430)

• Fix issue with non-ascii contents in doctest text files. (2434)

• Fix encoding errors for unicode warnings in Python 2. (2436)

• pytest.deprecated_call now captures PendingDeprecationWarning in
  context manager form. (2441)

Improved Documentation

• Addition of towncrier for changelog management. (2390)

3.1.0

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

New Features

• The pytest-warnings plugin has been integrated into the core and now pytest automatically
  captures and displays warnings at the end of the test session.

.. warning::

This feature may disrupt test suites which apply and treat warnings themselves, and can be
disabled in your pytest.ini:

.. code-block:: ini

 [pytest]
 addopts = -p no:warnings

See the warnings documentation page <https://docs.pytest.org/en/latest/warnings.html>_ for more
information.

Thanks nicoddemus_ for the PR.

• Added junit_suite_name ini option to specify root <testsuite> name for JUnit XML reports (533_).

• Added an ini option doctest_encoding to specify which encoding to use for doctest files.
  Thanks wheerd_ for the PR (2101_).

• pytest.warns now checks for subclass relationship rather than
  class equality. Thanks lesteve_ for the PR (2166_)

• pytest.raises now asserts that the error message matches a text or regex
  with the match keyword argument. Thanks Kriechi_ for the PR.

• pytest.param can be used to declare test parameter sets with marks and test ids.
  Thanks RonnyPfannschmidt_ for the PR.

Changes

• remove all internal uses of pytest_namespace hooks,
  this is to prepare the removal of preloadconfig in pytest 4.0
  Thanks to RonnyPfannschmidt_ for the PR.

• pytest now warns when a callable ids raises in a parametrized test. Thanks fogo_ for the PR.

• It is now possible to skip test classes from being collected by setting a
  __test__ attribute to False in the class body (2007). Thanks
  to syre for the report and lwm_ for the PR.

• Change junitxml.py to produce reports that comply with Junitxml schema.
  If the same test fails with failure in call and then errors in teardown
  we split testcase element into two, one containing the error and the other
  the failure. (2228) Thanks to kkoukiou for the PR.

• Testcase reports with a url attribute will now properly write this to junitxml.
  Thanks fushi_ for the PR (1874_).

• Remove common items from dict comparision output when verbosity=1. Also update
  the truncation message to make it clearer that pytest truncates all
  assertion messages if verbosity < 2 (1512).
  Thanks mattduck for the PR

• --pdbcls no longer implies --pdb. This makes it possible to use
  addopts=--pdbcls=module.SomeClass on pytest.ini. Thanks davidszotten_ for
  the PR (1952_).

• fix 2013_: turn RecordedWarning into namedtuple,
  to give it a comprehensible repr while preventing unwarranted modification.

• fix 2208_: ensure a iteration limit for pytest.compat.get_real_func.
  Thanks RonnyPfannschmidt for the report and PR.

• Hooks are now verified after collection is complete, rather than right after loading installed plugins. This
  makes it easy to write hooks for plugins which will be loaded during collection, for example using the
  pytest_plugins special variable (1821).
  Thanks nicoddemus for the PR.

• Modify pytest_make_parametrize_id() hook to accept argname as an
  additional parameter.
  Thanks unsignedint_ for the PR.

• Add venv to the default norecursedirs setting.
  Thanks The-Compiler_ for the PR.

• PluginManager.import_plugin now accepts unicode plugin names in Python 2.
  Thanks reutsharabani_ for the PR.

• fix 2308: When using both --lf and --ff, only the last failed tests are run.
  Thanks ojii for the PR.

• Replace minor/patch level version numbers in the documentation with placeholders.
  This significantly reduces change-noise as different contributors regnerate
  the documentation on different platforms.
  Thanks RonnyPfannschmidt_ for the PR.

• fix 2391: consider pytest_plugins on all plugin modules
  Thanks RonnyPfannschmidt for the PR.

Bug Fixes

• Fix AttributeError on sys.stdout.buffer / sys.stderr.buffer
  while using capsys fixture in python 3. (1407).
  Thanks to asottile.

• Change capture.py's DontReadFromInput class to throw io.UnsupportedOperation errors rather
  than ValueErrors in the fileno method (2276).
  Thanks metasyn and vlad-dragos_ for the PR.

• Fix exception formatting while importing modules when the exception message
  contains non-ascii characters (2336).
  Thanks fabioz for the report and nicoddemus_ for the PR.

• Added documentation related to issue (1937)
  Thanks skylarjhdownes for the PR.

• Allow collecting files with any file extension as Python modules (2369).
  Thanks Kodiologist for the PR.

• Show the correct error message when collect "parametrize" func with wrong args (2383).
  Thanks The-Compiler for the report and robin0371_ for the PR.

3.0.7

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

• Fix issue in assertion rewriting breaking due to modules silently discarding
  other modules when importing fails
  Notably, importing the anydbm module is fixed. (2248).
  Thanks pfhayes for the PR.

• junitxml: Fix problematic case where system-out tag occured twice per testcase
  element in the XML report. Thanks kkoukiou_ for the PR.

  (2137). Thanks to gst for the report and mbyt_ for the PR.

• Ignore exceptions raised from descriptors (e.g. properties) during Python test collection (2234).
  Thanks to bluetech.

• --override-ini now correctly overrides some fundamental options like python_files (2238).
  Thanks sirex for the report and nicoddemus_ for the PR.

  Thanks tgoodlet for the report and nicoddemus_ for the PR.

• Fix internal errors when an unprintable AssertionError is raised inside a test.
  Thanks omerhadari_ for the PR.

• Skipping plugin now also works with test items generated by custom collectors (2231).
  Thanks to vidartf.

• Fix trailing whitespace in console output if no .ini file presented (2281). Thanks fbjorn for the PR.

• Conditionless xfail markers no longer rely on the underlying test item
  being an instance of PyobjMixin, and can therefore apply to tests not
  collected by the built-in python test collector. Thanks barneygale_ for the
  PR.

3.0.6

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

• pytest no longer generates PendingDeprecationWarning from its own operations, which was introduced by mistake in version 3.0.5 (2118).
  Thanks to nicoddemus for the report and RonnyPfannschmidt_ for the PR.

• pytest no longer recognizes coroutine functions as yield tests (2129).
  Thanks to malinoff for the PR.

• Plugins loaded by the PYTEST_PLUGINS environment variable are now automatically
  considered for assertion rewriting (2185).
  Thanks nicoddemus for the PR.

• Improve error message when pytest.warns fails (2150). The type(s) of the
  expected warnings and the list of caught warnings is added to the
  error message. Thanks lesteve for the PR.

• Fix pytester internal plugin to work correctly with latest versions of
  zope.interface (1989). Thanks nicoddemus for the PR.

• Assert statements of the pytester plugin again benefit from assertion rewriting (1920).
  Thanks RonnyPfannschmidt for the report and nicoddemus_ for the PR.

• Specifying tests with colons like test_foo.py::test_bar for tests in
  subdirectories with ini configuration files now uses the correct ini file
  (2148). Thanks pelme.

• Fail testdir.runpytest().assert_outcomes() explicitly if the pytest
  terminal output it relies on is missing. Thanks to eli-b_ for the PR.

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.

3.0.4

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

• Import errors when collecting test modules now display the full traceback (1976).
  Thanks cwitty for the report and nicoddemus_ for the PR.

• Fix confusing command-line help message for custom options with two or more metavar properties (2004).
  Thanks okulynyak and davehunt_ for the report and nicoddemus_ for the PR.

• When loading plugins, import errors which contain non-ascii messages are now properly handled in Python 2 (1998).
  Thanks nicoddemus for the PR.

• Fixed cyclic reference when pytest.raises is used in context-manager form (1965). Also as a
  result of this fix, sys.exc_info() is left empty in both context-manager and function call usages.
  Previously, sys.exc_info would contain the exception caught by the context manager,
  even when the expected exception occurred.
  Thanks MSeifert04 for the report and the PR.

• Fixed false-positives warnings from assertion rewrite hook for modules that were rewritten but
  were later marked explicitly by pytest.register_assert_rewrite
  or implicitly as a plugin (2005).
  Thanks RonnyPfannschmidt for the report and nicoddemus_ for the PR.

• Report teardown output on test failure (442).
  Thanks matclab for the PR.

• Fix teardown error message in generated xUnit XML.
  Thanks gdyuldin_ for the PR.

• Properly handle exceptions in multiprocessing tasks (1984).
  Thanks adborden for the report and nicoddemus_ for the PR.

• Clean up unittest TestCase objects after tests are complete (1649).
  Thanks d_b_w for the report and PR.

3.0.3

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

• The ids argument to parametrize again accepts unicode strings
  in Python 2 (1905).
  Thanks philpep for the report and nicoddemus_ for the PR.

• Assertions are now being rewritten for plugins in development mode
  (pip install -e) (1934).
  Thanks nicoddemus for the PR.

  Thanks raquel-ucl for the PR.

• Got rid of AttributeError: 'Module' object has no attribute '_obj' exception
  in Python 3 (1944).
  Thanks axil for the PR.

• Explain a bad scope value passed to fixture declarations or
  a MetaFunc.parametrize() call. Thanks tgoodlet_ for the PR.

• This version includes pluggy-0.4.0, which correctly handles
  VersionConflict errors in plugins (704).
  Thanks nicoddemus for the PR.

3.0.2

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

• Improve error message when passing non-string ids to pytest.mark.parametrize (1857).
  Thanks okken for the report and nicoddemus_ for the PR.

• Add buffer attribute to stdin stub class pytest.capture.DontReadFromInput
  Thanks joguSD_ for the PR.

• Fix UnicodeEncodeError when string comparison with unicode has failed. (1864)
  Thanks AiOO for the PR.

• pytest_plugins is now handled correctly if defined as a string (as opposed as
  a sequence of strings) when modules are considered for assertion rewriting.
  Due to this bug, much more modules were being rewritten than necessary
  if a test suite uses pytest_plugins to load internal plugins (1888).
  Thanks jaraco for the report and nicoddemus_ for the PR (1891_).

• Do not call tearDown and cleanups when running tests from
  unittest.TestCase subclasses with --pdb
  enabled. This allows proper post mortem debugging for all applications
  which have significant logic in their tearDown machinery (1890). Thanks
  mbyt for the PR.

• Fix use of deprecated getfuncargvalue method in the internal doctest plugin.
  Thanks ViviCoder_ for the report (1898_).

3.0.0

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

Incompatible changes

A number of incompatible changes were made in this release, with the intent of removing features deprecated for a long
time or change existing behaviors in order to make them less surprising/more useful.

• Reinterpretation mode has now been removed. Only plain and rewrite
  mode are available, consequently the --assert=reinterp option is
  no longer available. This also means files imported from plugins or
  conftest.py will not benefit from improved assertions by
  default, you should use pytest.register_assert_rewrite() to
  explicitly turn on assertion rewriting for those files. Thanks
  flub_ for the PR.

• The following deprecated commandline options were removed:

• --genscript: no longer supported;
• --no-assert: use --assert=plain instead;
• --nomagic: use --assert=plain instead;
• --report: use -r instead;

Thanks to RedBeardCode_ for the PR (1664_).

• ImportErrors in plugins now are a fatal error instead of issuing a
  pytest warning (1479). Thanks to The-Compiler for the PR.

• Removed support code for Python 3 versions < 3.3 (1627_).

• Removed all py.test-X* entry points. The versioned, suffixed entry points
  were never documented and a leftover from a pre-virtualenv era. These entry
  points also created broken entry points in wheels, so removing them also
  removes a source of confusion for users (1632).
  Thanks obestwalter for the PR.

• pytest.skip() now raises an error when used to decorate a test function,
  as opposed to its original intent (to imperatively skip a test inside a test function). Previously
  this usage would cause the entire module to be skipped (607).
  Thanks omarkohl for the complete PR (1519_).

• Exit tests if a collection error occurs. A poll indicated most users will hit CTRL-C
  anyway as soon as they see collection errors, so pytest might as well make that the default behavior (1421).
  A --continue-on-collection-errors option has been added to restore the previous behaviour.
  Thanks olegpidsadnyi and omarkohl_ for the complete PR (1628_).

• Renamed the pytest pdb module (plugin) into debugging to avoid clashes with the builtin pdb module.

• Raise a helpful failure message when requesting a parametrized fixture at runtime,
  e.g. with request.getfixturevalue. Previously these parameters were simply
  never defined, so a fixture decorated like pytest.fixture(params=[0, 1, 2])
  only ran once (460).
  Thanks to nikratio for the bug report, RedBeardCode_ and tomviner_ for the PR.

• _pytest.monkeypatch.monkeypatch class has been renamed to _pytest.monkeypatch.MonkeyPatch
  so it doesn't conflict with the monkeypatch fixture.

• --exitfirst / -x can now be overridden by a following --maxfail=N
  and is just a synonym for --maxfail=1.

New Features

• Support nose-style __test__ attribute on methods of classes,
  including unittest-style Classes. If set to False, the test will not be
  collected.

• New doctest_namespace fixture for injecting names into the
  namespace in which doctests run.
  Thanks milliams_ for the complete PR (1428_).

• New --doctest-report option available to change the output format of diffs
  when running (failing) doctests (implements 1749).
  Thanks hartym for the PR.

• New name argument to pytest.fixture decorator which allows a custom name
  for a fixture (to solve the funcarg-shadowing-fixture problem).
  Thanks novas0x2a_ for the complete PR (1444_).

• New approx() function for easily comparing floating-point numbers in
  tests.
  Thanks kalekundert_ for the complete PR (1441_).

• Ability to add global properties in the final xunit output file by accessing
  the internal junitxml plugin (experimental).
  Thanks tareqalayan_ for the complete PR 1454_).

• New ExceptionInfo.match() method to match a regular expression on the
  string representation of an exception (372).
  Thanks omarkohl for the complete PR (1502_).

• __tracebackhide__ can now also be set to a callable which then can decide
  whether to filter the traceback based on the ExceptionInfo object passed
  to it. Thanks The-Compiler_ for the complete PR (1526_).

• New pytest_make_parametrize_id(config, val) hook which can be used by plugins to provide
  friendly strings for custom types.
  Thanks palaviv_ for the PR.

• capsys and capfd now have a disabled() context-manager method, which
  can be used to temporarily disable capture within a test.
  Thanks nicoddemus_ for the PR.

• New cli flag --fixtures-per-test: shows which fixtures are being used
  for each selected test item. Features doc strings of fixtures by default.
  Can also show where fixtures are defined if combined with -v.
  Thanks hackebrot_ for the PR.

• Introduce pytest command as recommended entry point. Note that py.test
  still works and is not scheduled for removal. Closes proposal
  1629. Thanks obestwalter and davehunt_ for the complete PR
  (1633_).

• New cli flags:

• --setup-plan: performs normal collection and reports
  the potential setup and teardown and does not execute any fixtures and tests;
• --setup-only: performs normal collection, executes setup and teardown of
  fixtures and reports them;
• --setup-show: performs normal test execution and additionally shows
  setup and teardown of fixtures;
• --keep-duplicates: py.test now ignores duplicated paths given in the command
  line. To retain the previous behavior where the same test could be run multiple
  times by specifying it in the command-line multiple times, pass the --keep-duplicates
  argument (1609_);

Thanks d6e, kvas-it, sallner, ioggstream and omarkohl_ for the PRs.

• New CLI flag --override-ini/-o: overrides values from the ini file.
  For example: "-o xfail_strict=True"'.
  Thanks blueyed_ and fengxx_ for the PR.

• New hooks:

• pytest_fixture_setup(fixturedef, request): executes fixture setup;
• pytest_fixture_post_finalizer(fixturedef): called after the fixture's
  finalizer and has access to the fixture's result cache.

Thanks d6e, sallner.

• Issue warnings for asserts whose test is a tuple literal. Such asserts will
  never fail because tuples are always truthy and are usually a mistake
  (see 1562). Thanks kvas-it, for the PR.

• Allow passing a custom debugger class (e.g. --pdbcls=IPython.core.debugger:Pdb).
  Thanks to anntzer_ for the PR.

Changes

• Plugins now benefit from assertion rewriting. Thanks
  sober7, nicoddemus and flub_ for the PR.

• Change report.outcome for xpassed tests to "passed" in non-strict
  mode and "failed" in strict mode. Thanks to hackebrot_ for the PR
  (1795) and gprasad84 for report (1546_).

• Tests marked with xfail(strict=False) (the default) now appear in
  JUnitXML reports as passing tests instead of skipped.
  Thanks to hackebrot_ for the PR (1795_).

• Highlight path of the file location in the error report to make it easier to copy/paste.
  Thanks suzaku_ for the PR (1778_).

• Fixtures marked with pytest.fixture can now use yield statements exactly like
  those marked with the pytest.yield_fixture decorator. This change renders
  pytest.yield_fixture deprecated and makes pytest.fixture with yield statements
  the preferred way to write teardown code (1461).
  Thanks csaftoiu for bringing this to attention and nicoddemus_ for the PR.

• Explicitly passed parametrize ids do not get escaped to ascii (1351).
  Thanks ceridwen for the PR.

• Fixtures are now sorted in the error message displayed when an unknown
  fixture is declared in a test function.
  Thanks nicoddemus_ for the PR.

• pytest_terminal_summary hook now receives the exitstatus
  of the test session as argument. Thanks blueyed_ for the PR (1809_).

• Parametrize ids can accept None as specific test id, in which case the
  automatically generated id for that argument will be used.
  Thanks palaviv_ for the complete PR (1468_).

• The parameter to xunit-style setup/teardown methods (setup_method,
  setup_module, etc.) is now optional and may be omitted.
  Thanks okken_ for bringing this to attention and nicoddemus_ for the PR.

• Improved automatic id generation selection in case of duplicate ids in
  parametrize.
  Thanks palaviv_ for the complete PR (1474_).

• Now pytest warnings summary is shown up by default. Added a new flag
  --disable-pytest-warnings to explicitly disable the warnings summary (1668_).

• Make ImportError during collection more explicit by reminding
  the user to check the name of the test module/package(s) (1426).
  Thanks omarkohl for the complete PR (1520_).

• Add build/ and dist/ to the default --norecursedirs list. Thanks
  mikofski_ for the report and tomviner_ for the PR (1544_).

• pytest.raises in the context manager form accepts a custom
  message to raise when no exception occurred.
  Thanks palaviv_ for the complete PR (1616_).

• conftest.py files now benefit from assertion rewriting; previously it
  was only available for test modules. Thanks flub, sober7 and
  nicoddemus_ for the PR (1619_).

• Text documents without any doctests no longer appear as "skipped".
  Thanks graingert_ for reporting and providing a full PR (1580_).

• Ensure that a module within a namespace package can be found when it
  is specified on the command line together with the --pyargs
  option. Thanks to taschini_ for the PR (1597_).

• Always include full assertion explanation during assertion rewriting. 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
  tomviner_ for the PR.

• OptionGroup.addoption() now checks if option names were already
  added before, to make it easier to track down issues like 1618_.
  Before, you only got exceptions later from argparse library,
  giving no clue about the actual reason for double-added options.

• yield-based tests are considered deprecated and will be removed in pytest-4.0.
  Thanks nicoddemus_ for the PR.

• [pytest] sections in setup.cfg files should now be named [tool:pytest]
  to avoid conflicts with other distutils commands (see 567). [pytest] sections in
  pytest.ini or tox.ini files are supported and unchanged.
  Thanks nicoddemus for the PR.

• Using pytest_funcarg__ prefix to declare fixtures is considered deprecated and will be
  removed in pytest-4.0 (1684).
  Thanks nicoddemus for the PR.

• Passing a command-line string to pytest.main() is considered deprecated and scheduled
  for removal in pytest-4.0. It is recommended to pass a list of arguments instead (1723_).

• Rename getfuncargvalue to getfixturevalue. getfuncargvalue is
  still present but is now considered deprecated. Thanks to RedBeardCode_ and tomviner_
  for the PR (1626_).

• optparse type usage now triggers DeprecationWarnings (1740_).

• optparse backward compatibility supports float/complex types (457_).

• Refined logic for determining the rootdir, considering only valid
  paths which fixes a number of issues: 1594, 1435 and 1471.
  Updated the documentation according to current behavior. Thanks to
  blueyed, davehunt_ and matthiasha_ 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
  tomviner_ for PR.

• Better message in case of not using parametrized variable (see 1539).
  Thanks to tramwaj29 for the PR.

• Updated docstrings with a more uniform style.

• Add stderr write for pytest.exit(msg) during startup. Previously the message was never shown.
  Thanks BeyondEvil_ for reporting 1210. Thanks to JonathonSonesen and
  tomviner_ for the PR.

• No longer display the incorrect test deselection reason (1372).
  Thanks ronnypfannschmidt for the PR.

• The --resultlog command line option has been deprecated: it is little used
  and there are more modern and better alternatives (see 830).
  Thanks nicoddemus for the PR.

• Improve error message with fixture lookup errors: add an 'E' to the first
  line and '>' to the rest. Fixes 717. Thanks blueyed for reporting and
  a PR, eolo999_ for the initial PR and tomviner_ for his guidance during
  EuroPython2016 sprint.

2.9.0

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

New Features

• New pytest.mark.skip mark, which unconditionally skips marked tests.
  Thanks MichaelAquilina_ for the complete PR (1040_).

• --doctest-glob may now be passed multiple times in the command-line.
  Thanks jab_ and nicoddemus_ for the PR.

• New -rp and -rP reporting options give the summary and full output
  of passing tests, respectively. Thanks to codewarrior0_ for the PR.

• pytest.mark.xfail now has a strict option, which makes XPASS
  tests to fail the test suite (defaulting to False). There's also a
  xfail_strict ini option that can be used to configure it project-wise.
  Thanks rabbbit_ for the request and nicoddemus_ for the PR (1355_).

• Parser.addini now supports options of type bool.
  Thanks nicoddemus_ for the PR.

• New ALLOW_BYTES doctest option. This strips b prefixes from byte strings
  in doctest output (similar to ALLOW_UNICODE).
  Thanks jaraco_ for the request and nicoddemus_ for the PR (1287_).

• Give a hint on KeyboardInterrupt to use the --fulltrace option to show the errors.
  Fixes 1366.
  Thanks to hpk42 for the report and RonnyPfannschmidt_ for the PR.

• Catch IndexError exceptions when getting exception source location.
  Fixes a pytest internal error for dynamically generated code (fixtures and tests)
  where source lines are fake by intention.

Changes

• Important: py.code <https://pylib.readthedocs.io/en/latest/code.html>_ has been
  merged into the pytest repository as pytest._code. This decision
  was made because py.code had very few uses outside pytest and the
  fact that it was in a different repository made it difficult to fix bugs on
  its code in a timely manner. The team hopes with this to be able to better
  refactor out and improve that code.
  This change shouldn't affect users, but it is useful to let users aware
  if they encounter any strange behavior.

Keep in mind that the code for pytest._code is private and
experimental, so you definitely should not import it explicitly!

Please note that the original py.code is still available in
pylib <https://pylib.readthedocs.io>_.

• pytest_enter_pdb now optionally receives the pytest config object.
  Thanks nicoddemus_ for the PR.

• Removed code and documentation for Python 2.5 or lower versions,
  including removal of the obsolete _pytest.assertion.oldinterpret module.
  Thanks nicoddemus_ for the PR (1226_).

• Comparisons now always show up in full when CI or BUILD_NUMBER is
  found in the environment, even when -vv isn't used.
  Thanks The-Compiler_ for the PR.

• --lf and --ff now support long names: --last-failed and
  --failed-first respectively.
  Thanks MichaelAquilina_ for the PR.

• Added expected exceptions to pytest.raises fail message.

• Collection only displays progress ("collecting X items") when in a terminal.
  This avoids cluttering the output when using --color=yes to obtain
  colors in CI integrations systems (1397_).

Bug Fixes

• The -s and -c options should now work under xdist;
  Config.fromdictargs now represents its input much more faithfully.
  Thanks to bukzor_ for the complete PR (680_).

• Fix (1290): support Python 3.5's ```` operator in assertion rewriting.
  Thanks Shinkenjoe for report with test case and `tomviner`_ for the PR.

• Fix formatting utf-8 explanation messages (1379).
  Thanks biern for the PR.

• Fix traceback style docs_ to describe all of the available options
  (auto/long/short/line/native/no), with auto being the default since v2.6.
  Thanks hackebrot_ for the PR.

• Fix (1422_): junit record_xml_property doesn't allow multiple records
  with same name.

  Thanks Alex Gaynor for the issue and Eric Hunsberger for the PR.

• fix issue 1073: avoid calling getattr on potential plugin objects.
  This fixes an incompatibility with pytest-django. Thanks Andreas Pelme,
  Bruno Oliveira and Ronny Pfannschmidt for contributing and Holger Krekel
  for the fix.

• Fix issue 704: handle versionconflict during plugin loading more
  gracefully. Thanks Bruno Oliveira for the PR.

• Fix issue 1064: ""--junitxml" regression when used with the
  "pytest-xdist" plugin, with test reports being assigned to the wrong tests.
  Thanks Daniel Grunwald for the report and Bruno Oliveira for the PR.

• (experimental) adapt more SEMVER style versioning and change meaning of
  master branch in git repo: "master" branch now keeps the bugfixes, changes
  aimed for micro releases. "features" branch will only be released
  with minor or major pytest releases.

• Fix issue 766 by removing documentation references to distutils.
  Thanks Russel Winder.

• Fix issue 1030: now byte-strings are escaped to produce item node ids
  to make them always serializable.
  Thanks Andy Freeland for the report and Bruno Oliveira for the PR.

• Python 2: if unicode parametrized values are convertible to ascii, their
  ascii representation is used for the node id.

• Fix issue 411: Add eq method to assertion comparison example.
  Thanks Ben Webb.
• Fix issue 653: deprecated_call can be used as context manager.

• fix issue 877: properly handle assertion explanations with non-ascii repr
  Thanks Mathieu Agopian for the report and Ronny Pfannschmidt for the PR.

• fix issue 1029: transform errors when writing cache values into pytest-warnings

2.8.0

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

• new --lf and -ff options to run only the last failing tests or
  "failing tests first" from the last run. This functionality is provided
  through porting the formerly external pytest-cache plugin into pytest core.
  BACKWARD INCOMPAT: if you used pytest-cache's functionality to persist
  data between test runs be aware that we don't serialize sets anymore.
  Thanks Ronny Pfannschmidt for most of the merging work.

• "-r" option now accepts "a" to include all possible reports, similar
  to passing "fEsxXw" explicitly (isse960).
  Thanks Abhijeet Kasurde for the PR.

• avoid python3.5 deprecation warnings by introducing version
  specific inspection helpers, thanks Michael Droettboom.

• fix issue562: nose.tools.istest now fully respected.

• fix issue934: when string comparison fails and a diff is too large to display
  without passing -vv, still show a few lines of the diff.
  Thanks Florian Bruhin for the report and Bruno Oliveira for the PR.

• fix issue736: Fix a bug where fixture params would be discarded when combined
  with parametrization markers.
  Thanks to Markus Unterwaditzer for the PR.

• fix issue710: introduce ALLOW_UNICODE doctest option: when enabled, the
  u prefix is stripped from unicode strings in expected doctest output. This
  allows doctests which use unicode to run in Python 2 and 3 unchanged.
  Thanks Jason R. Coombs for the report and Bruno Oliveira for the PR.

• parametrize now also generates meaningful test IDs for enum, regex and class
  objects (as opposed to class instances).
  Thanks to Florian Bruhin for the PR.

• Add 'warns' to assert that warnings are thrown (like 'raises').
  Thanks to Eric Hunsberger for the PR.

• Fix issue683: Do not apply an already applied mark. Thanks ojake for the PR.

• Deal with capturing failures better so fewer exceptions get lost to
  /dev/null. Thanks David Szotten for the PR.

• fix issue730: deprecate and warn about the --genscript option.
  Thanks Ronny Pfannschmidt for the report and Christian Pommranz for the PR.

• fix issue751: multiple parametrize with ids bug if it parametrizes class with
  two or more test methods. Thanks Sergey Chipiga for reporting and Jan
  Bednarik for PR.

• fix issue82: avoid loading conftest files from setup.cfg/pytest.ini/tox.ini
  files and upwards by default (--confcutdir can still be set to override this).
  Thanks Bruno Oliveira for the PR.

• fix issue768: docstrings found in python modules were not setting up session
  fixtures. Thanks Jason R. Coombs for reporting and Bruno Oliveira for the PR.

• added tmpdir_factory, a session-scoped fixture that can be used to create
  directories under the base temporary directory. Previously this object was
  installed as a _tmpdirhandler attribute of the config object, but now it
  is part of the official API and using config._tmpdirhandler is
  deprecated.
  Thanks Bruno Oliveira for the PR.

• fix issue808: pytest's internal assertion rewrite hook now implements the
  optional PEP302 get_data API so tests can access data files next to them.
  Thanks xmo-odoo for request and example and Bruno Oliveira for
  the PR.

• rootdir and inifile are now displayed during usage errors to help
  users diagnose problems such as unexpected ini files which add
  unknown options being picked up by pytest. Thanks to Pavel Savchenko for
  bringing the problem to attention in 821 and Bruno Oliveira for the PR.

• Summary bar now is colored yellow for warning
  situations such as: all tests either were skipped or xpass/xfailed,
  or no tests were run at all (this is a partial fix for issue500).

• fix issue812: pytest now exits with status code 5 in situations where no
  tests were run at all, such as the directory given in the command line does
  not contain any tests or as result of a command line option filters
  all out all tests (-k for example).
  Thanks Eric Siegerman (issue812) and Bruno Oliveira for the PR.

• Summary bar now is colored yellow for warning
  situations such as: all tests either were skipped or xpass/xfailed,
  or no tests were run at all (related to issue500).
  Thanks Eric Siegerman.

• New testpaths ini option: list of directories to search for tests
  when executing pytest from the root directory. This can be used
  to speed up test collection when a project has well specified directories
  for tests, being usually more practical than configuring norecursedirs for
  all directories that do not contain tests.
  Thanks to Adrian for idea (694) and Bruno Oliveira for the PR.

• fix issue713: JUnit XML reports for doctest failures.
  Thanks Punyashloka Biswal.

• fix issue970: internal pytest warnings now appear as "pytest-warnings" in
  the terminal instead of "warnings", so it is clear for users that those
  warnings are from pytest and not from the builtin "warnings" module.
  Thanks Bruno Oliveira.

• Include setup and teardown in junitxml test durations.
  Thanks Janne Vanhala.

• fix issue735: assertion failures on debug versions of Python 3.4+

• new option --import-mode to allow to change test module importing
  behaviour to append to sys.path instead of prepending. This better allows
  to run test modules against installed versions of a package even if the
  package under test has the same import root. In this example::

   testing/__init__.py
   testing/test_pkg_under_test.py
   pkg_under_test/

the tests will run against the installed version
of pkg_under_test when --import-mode=append is used whereas
by default they would always pick up the local version. Thanks Holger Krekel.

• pytester: add method TmpTestdir.delete_loaded_modules(), and call it
  from inline_run() to allow temporary modules to be reloaded.
  Thanks Eduardo Schettino.

• internally refactor pluginmanager API and code so that there
  is a clear distinction between a pytest-agnostic rather simple
  pluginmanager and the PytestPluginManager which adds a lot of
  behaviour, among it handling of the local conftest files.
  In terms of documented methods this is a backward compatible
  change but it might still break 3rd party plugins which relied on
  details like especially the pluginmanager.add_shutdown() API.
  Thanks Holger Krekel.

• pluginmanagement: introduce pytest.hookimpl and
  pytest.hookspec decorators for setting impl/spec
  specific parameters. This substitutes the previous
  now deprecated use of pytest.mark which is meant to
  contain markers for test functions only.

• write/refine docs for "writing plugins" which now have their
  own page and are separate from the "using/installing plugins`` page.

• fix issue732: properly unregister plugins from any hook calling
  sites allowing to have temporary plugins during test execution.

• deprecate and warn about __multicall__ argument in ho
