-----
- Fix issue #766 by removing documentation references to distutils.
Thanks Russel Winder.
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 installated 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 hook
implementations. Use the ``hookwrapper`` mechanism instead already
introduced with pytest-2.7.
- speed up pytest's own test suite considerably by using inprocess
tests by default (testrun can be modified with --runpytest=subprocess
to create subprocesses in many places instead). The main
APIs to run pytest in a test is "runpytest()" or "runpytest_subprocess"
and "runpytest_inprocess" if you need a particular way of running
the test. In all cases you get back a RunResult but the inprocess
one will also have a "reprec" attribute with the recorded events/reports.
- fix monkeypatch.setattr("x.y", raising=False) to actually not raise
if "y" is not a pre-existing attribute. Thanks Florian Bruhin.
- fix issue741: make running output from testdir.run copy/pasteable
Thanks Bruno Oliveira.
- add a new ``--noconftest`` argument which ignores all ``conftest.py`` files.
- add ``file`` and ``line`` attributes to JUnit-XML output.
- fix issue890: changed extension of all documentation files from ``txt`` to
``rst``. Thanks to Abhijeet for the PR.
- fix issue714: add ability to apply indirect=True parameter on particular argnames.
Thanks Elizaveta239.
- fix issue714: add ability to apply indirect=True parameter on particular argnames.
- fix issue890: changed extension of all documentation files from ``txt`` to
``rst``. Thanks to Abhijeet for the PR.
- fix issue957: "# doctest: SKIP" option will now register doctests as SKIPPED
rather than PASSED.
Thanks Thomas Grainger for the report and Bruno Oliveira for the PR.
- issue951: add new record_xml_property fixture, that supports logging
additional information on xml output. Thanks David Diaz for the PR.
- issue949: paths after normal options (for example `-s`, `-v`, etc) are now
properly used to discover `rootdir` and `ini` files.
Thanks Peter Lauri for the report and Bruno Oliveira for the PR.
2.7.3 (compared to 2.7.2)
-----------------------------
- Allow 'dev', 'rc', or other non-integer version strings in `importorskip`.
Thanks to Eric Hunsberger for the PR.
- fix issue856: consider --color parameter in all outputs (for example
--fixtures). Thanks Barney Gale for the report and Bruno Oliveira for the PR.
- fix issue855: passing str objects as `plugins` argument to pytest.main
is now interpreted as a module name to be imported and registered as a
plugin, instead of silently having no effect.
Thanks xmo-odoo for the report and Bruno Oliveira for the PR.
- fix issue744: fix for ast.Call changes in Python 3.5+. Thanks
Guido van Rossum, Matthias Bussonnier, Stefan Zimmermann and
Thomas Kluyver.
- fix issue842: applying markers in classes no longer propagate this markers
to superclasses which also have markers.
Thanks xmo-odoo for the report and Bruno Oliveira for the PR.
- preserve warning functions after call to pytest.deprecated_call. Thanks
Pieter Mulder for PR.
- fix issue854: autouse yield_fixtures defined as class members of
unittest.TestCase subclasses now work as expected.
Thannks xmo-odoo for the report and Bruno Oliveira for the PR.
- fix issue833: --fixtures now shows all fixtures of collected test files, instead of just the
fixtures declared on the first one.
Thanks Florian Bruhin for reporting and Bruno Oliveira for the PR.
- fix issue863: skipped tests now report the correct reason when a skip/xfail
condition is met when using multiple markers.
Thanks Raphael Pierzina for reporting and Bruno Oliveira for the PR.
- optimized tmpdir fixture initialization, which should make test sessions
faster (specially when using pytest-xdist). The only visible effect
is that now pytest uses a subdirectory in the $TEMP directory for all
directories created by this fixture (defaults to $TEMP/pytest-$USER).
Thanks Bruno Oliveira for the PR.
2.7.2 (compared to 2.7.1)
-----------------------------
- fix issue767: pytest.raises value attribute does not contain the exception
instance on Python 2.6. Thanks Eric Siegerman for providing the test
case and Bruno Oliveira for PR.
- Automatically create directory for junitxml and results log.
Thanks Aron Curzon.
- fix issue713: JUnit XML reports for doctest failures.
Thanks Punyashloka Biswal.
- fix issue735: assertion failures on debug versions of Python 3.4+
Thanks Benjamin Peterson.
- fix issue114: skipif marker reports to internal skipping plugin;
Thanks Floris Bruynooghe for reporting and Bruno Oliveira for the PR.
- fix issue748: unittest.SkipTest reports to internal pytest unittest plugin.
Thanks Thomas De Schampheleire for reporting and Bruno Oliveira for the PR.
- fix issue718: failed to create representation of sets containing unsortable
elements in python 2. Thanks Edison Gustavo Muenz.
- fix issue756, fix issue752 (and similar issues): depend on py-1.4.29
which has a refined algorithm for traceback generation.
2.7.1 (compared to 2.7.0)
-----------------------------
- fix issue731: do not get confused by the braces which may be present
and unbalanced in an object's repr while collapsing False
explanations. Thanks Carl Meyer for the report and test case.
- fix issue553: properly handling inspect.getsourcelines failures in
FixtureLookupError which would lead to to an internal error,
obfuscating the original problem. Thanks talljosh for initial
diagnose/patch and Bruno Oliveira for final patch.
- fix issue660: properly report scope-mismatch-access errors
independently from ordering of fixture arguments. Also
avoid the pytest internal traceback which does not provide
information to the user. Thanks Holger Krekel.
- streamlined and documented release process. Also all versions
(in setup.py and documentation generation) are now read
from _pytest/__init__.py. Thanks Holger Krekel.
- fixed docs to remove the notion that yield-fixtures are experimental.
They are here to stay :) Thanks Bruno Oliveira.
- Support building wheels by using environment markers for the
requirements. Thanks Ionel Maries Cristian.
- fixed regression to 2.6.4 which surfaced e.g. in lost stdout capture printing
when tests raised SystemExit. Thanks Holger Krekel.
- reintroduced _pytest fixture of the pytester plugin which is used
at least by pytest-xdist.
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).
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.
- fix issue614: fixed pastebin support.
- fix issue620: add explanation in the --genscript target about what
the binary blob means. Thanks Dinu Gherman.
- fix issue614: fixed pastebin support.
2.6.3
-----------
- fix issue575: xunit-xml was reporting collection errors as failures
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.
2.6.2
-----------
- Added function pytest.freeze_includes(), which makes it easy to embed
pytest into executables using tools like cx_freeze.
See docs for examples and rationale. Thanks Bruno Oliveira.
- Improve assertion rewriting cache invalidation precision.
- 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.
- Implement issue549: user-provided assertion messages now no longer
replace the py.test introspection message but are shown in addition
to them.
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.
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.
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. Adapted
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 occurred 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.
