[py-dev] tox-1.3: virtualenv-based test run automizer

tox 1.3: the virtualenv-based test run automatizer =========================================================================== I am happy to announce tox 1.3, containing a few improvements over 1.2. TOX automates tedious test activities driven from a simple ``tox.ini`` file, including: * creation and management of different virtualenv environments with different Python interpreters * packaging and installing your package into each of them * running your test tool of choice, be it nose, py.test or unittest2 or other tools such as "sphinx" doc checks * testing dev packages against each other without needing to upload to PyPI Docs and examples are at: http://tox.testrun.org/ Installation: pip install -U tox code hosting and issue tracking on bitbucket: http://bitbucket.org/hpk42/tox best, Holger Krekel 1.3 ----------------- - fix: allow to specify wildcard filesystem paths when specifiying dependencies such that tox searches for the highest version - fix issue21: clear PIP_REQUIRES_VIRTUALENV which avoids pip installing to the wrong environment, thanks to bb's streeter - make the install step honour a testenv's setenv setting (thanks Ralf Schmitt)

[py-dev] pytest-2.2.1: bug fixes, better teardowns

pytest-2.2.1: bug fixes, better teardowns =========================================================================== pytest-2.2.1 is a minor backward-compatible release of the the py.test testing tool. It contains bug fixes and little improvements, including documentation fixes. If you are using the distributed testing plugin make sure to upgrade it to pytest-xdist-1.8. For general information see here: http://pytest.org/ To install or upgrade pytest: pip install -U pytest # or easy_install -U pytest Special thanks for helping on this release to Ronny Pfannschmidt, Jurko Gospodnetic and Ralf Schmitt. best, holger krekel Changes between 2.2.0 and 2.2.1 ---------------------------------------- - fix issue99 (in pytest and py) internallerrors with resultlog now produce better output - fixed by normalizing pytest_internalerror input arguments. - fix issue97 / traceback issues (in pytest and py) improve traceback output in conjunction with jinja2 and cython which hack tracebacks - fix issue93 (in pytest and pytest-xdist) avoid "delayed teardowns": the final test in a test node will now run its teardown directly instead of waiting for the end of the session. Thanks Dave Hunt for the good reporting and feedback. The pytest_runtest_protocol as well as the pytest_runtest_teardown hooks now have "nextitem" available which will be None indicating the end of the test run. - fix collection crash due to unknown-source collected items, thanks to Ralf Schmitt (fixed by depending on a more recent pylib)

[py-dev] QuickCheck plugin
by Jacek Generowicz Dec. 9, 2011

Dec. 9, 2011

Hi, QuickCheck is a property-based testing framework originating in Haskell. Its 3 key concepts are: 1. Tests are expressed as properties: invariants which should be satisfied for any appropriate test data. 2. The test data are randomly generated and fed to the property. 3. (this is the really interesting stroke of genius) When some data are found for which the test fails, QuickCheck attempts to simplify the data to obtain the minimal example that still fails. My questions are: 1. Are you aware of any work being done on integrating the QuickCheck idea with pytest? 2. QuickCheck generates new test invocations in response to failing tests; Pytest collects tests *before* they are run. Would these two seemingly conflicting features prose problems in trying to implement a QuickCheck plugin for pytest? 3. Would you have any general advice on how one might approach providing a QuickCheck clone on top of pytest? Thanks.
