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: &quot;-o xfail_strict=True&quot;'.
    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 &quot;passed&quot; in non-strict
    mode and &quot;failed&quot; 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.
