pytest 2.8
by Bruno Oliveira Sept. 18, 2015

Sept. 18, 2015

Hi all, pytest 2.8 has been released to pypi, with significant bug-fixes and features. In case you wonder, pytest is a widely used mature test runner both for unit and functional test purposes in python. See http://pytest.org for documentation and examples. Here's the changelog for this version: - 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.

ANN: python-blosc 1.2.8 released
by Francesc Alted Sept. 16, 2015

Sept. 16, 2015

============================= Announcing python-blosc 1.2.8 ============================= What is new? ============ This is a maintenance release. Internal C-Blosc has been upgraded to 1.7.0 (although new bitshuffle support has not been made public, as it seems not ready for production yet). Also, there is support for bytes-like objects that support the buffer interface as input to ``compress`` and ``decompress``. On Python 2.x this includes unicode, on Python 3.x it doesn't. Thanks to Valentin Haenel. Finally, a memory leak in ``decompress```has been hunted and fixed. And new tests have been added to catch possible leaks in the future. Thanks to Santi Villalba. For more info, you can have a look at the release notes in: https://github.com/Blosc/python-blosc/blob/master/RELEASE_NOTES.rst More docs and examples are available in the documentation site: http://python-blosc.blosc.org What is it? =========== Blosc (http://www.blosc.org) is a high performance compressor optimized for binary data. It has been designed to transmit data to the processor cache faster than the traditional, non-compressed, direct memory fetch approach via a memcpy() OS call. Blosc is the first compressor that is meant not only to reduce the size of large datasets on-disk or in-memory, but also to accelerate object manipulations that are memory-bound (http://www.blosc.org/docs/StarvingCPUs.pdf). See http://www.blosc.org/synthetic-benchmarks.html for some benchmarks on how much speed it can achieve in some datasets. Blosc works well for compressing numerical arrays that contains data with relatively low entropy, like sparse data, time series, grids with regular-spaced values, etc. python-blosc (http://python-blosc.blosc.org/) is the Python wrapper for the Blosc compression library. There is also a handy tool built on Blosc called Bloscpack (https://github.com/Blosc/bloscpack). It features a commmand line interface that allows you to compress large binary datafiles on-disk. It also comes with a Python API that has built-in support for serializing and deserializing Numpy arrays both on-disk and in-memory at speeds that are competitive with regular Pickle/cPickle machinery. Installing ========== python-blosc is in PyPI repository, so installing it is easy: $ pip install -U blosc # yes, you must omit the 'python-' prefix Download sources ================ The sources are managed through github services at: http://github.com/Blosc/python-blosc Documentation ============= There is Sphinx-based documentation site at: http://python-blosc.blosc.org/ Mailing list ============ There is an official mailing list for Blosc at: blosc(a)googlegroups.com http://groups.google.es/group/blosc Licenses ======== Both Blosc and its Python wrapper are distributed using the MIT license. See: https://github.com/Blosc/python-blosc/blob/master/LICENSES for more details. ---- **Enjoy data!** -- Francesc Alted

pytest-2.7.3: fixes and py35 compat
by holger krekel Sept. 15, 2015

Sept. 15, 2015

Hi all, I just pushed pytest-2.7.3 to pypi which contains bugfixes including compatibility to python3.5 which was released yesterday. In case you wonder, pytest is a widely used mature test runner both for unit and functional test purposes in python. See http://pytest.org for documentation and examples. Thanks to contributors for this release, among them: Bruno Oliveira, Florian Bruhin, Floris Bruynooghe, Ronny Pfannschmidt, Eric Hunsberg, Barney Gale, Guido van Rossum, Matthias Matthias Bussonier, Stefan Zimmermann, Thomas Kluyver, Pieter Mulder, Raphael Pierzina. best, holger krekel P.S.: we are also preparing a pytest-2.8 which has a much longer list of changes/features. 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.

ANN: Tribool 0.6.2 Released
by Grant Jenks Sept. 14, 2015

Sept. 14, 2015

Announcing the Release of Tribool Version 0.6.2 What is Tribool? ---------------- Tribool is an Apache2 licensed module for three-valued logic. More commonly found in SQL, three-valued logic defines truth tables over the values True, False, and Indeterminate. The third value is considered a state being one of True or False. Tribool implements logical operators on these values as immutable singletons. The implementation is pure-Python with 100% code coverage and complete documentation. What's new in 0.6.2? -------------------- - Implemented __copy__ and __deepcopy__ methods as part of `copy` module protocol. - Implemented __reduce__ as part of `pickle` module protocol. - Changed subclassing from `object` to `tuple` to prevent mutation of internal state. Links ----- - Documentation: http://www.grantjenks.com/docs/tribool/ - Download: https://pypi.python.org/pypi/tribool - Source: https://github.com/grantjenks/python_tribool - Issues: https://github.com/grantjenks/python_tribool/issues This release is backwards-compatible. Please upgrade.
