Changelog

3.0.2.dev

• 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.

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. 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.
