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. 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.

coverage 4.1 -> 4.2

4.2

---

• Since concurrency=multiprocessing uses subprocesses, options specified on
  the coverage.py command line will not be communicated down to them. Only
  options in the configuration file will apply to the subprocesses.
  Previously, the options didn't apply to the subprocesses, but there was no
  indication. Now it is an error to use --concurrency=multiprocessing and
  other run-affecting options on the command line. This prevents
  failures like those reported in issue 495_.
• Filtering the HTML report is now faster, thanks to Ville Skyttä.

4.2b1

---

Work from the PyCon 2016 Sprints!

• BACKWARD INCOMPATIBILITY: the coverage combine command now ignores an
  existing .coverage data file. It used to include that file in its
  combining. This caused confusing results, and extra tox "clean" steps. If
  you want the old behavior, use the new coverage combine --append option.
• The concurrency option can now take multiple values, to support programs
  using multiprocessing and another library such as eventlet. This is only
  possible in the configuration file, not from the command line. The
  configuration file is the only way for sub-processes to all run with the same
  options. Fixes issue 484_. Thanks to Josh Williams for prototyping.
• Using a concurrency setting of multiprocessing now implies
  --parallel so that the main program is measured similarly to the
  sub-processes.
• When using automatic subprocess measurement, running coverage commands
  would create spurious data files. This is now fixed, thanks to diagnosis and
  testing by Dan Riti. Closes issue 492.
• A new configuration option, report:sort, controls what column of the
  text report is used to sort the rows. Thanks to Dan Wandschneider, this
  closes issue 199_.
• The HTML report has a more-visible indicator for which column is being
  sorted. Closes issue 298_, thanks to Josh Williams.
• If the HTML report cannot find the source for a file, the message now
  suggests using the -i flag to allow the report to continue. Closes
  issue 231_, thanks, Nathan Land.
• When reports are ignoring errors, there's now a warning if a file cannot be
  parsed, rather than being silently ignored. Closes issue 396_. Thanks,
  Matthew Boehm.
• A new option for coverage debug is available: coverage debug config
  shows the current configuration. Closes issue 454_, thanks to Matthew
  Boehm.
• Running coverage as a module (python -m coverage) no longer shows the
  program name as __main__.py. Fixes issue 478_. Thanks, Scott Belden.
• The test_helpers module has been moved into a separate pip-installable
  package: unittest-mixins_.
