pytest-2.3: improved fixtures/funcargs and unittest support
by holger krekel Oct. 19, 2012

Oct. 19, 2012

pytest-2.3: improved fixtures / better unittest integration ============================================================================= pytest-2.3 comes with many major improvements for fixture/funcarg management and parametrized testing in Python. It is now easier, more efficient and more predicatable to re-run the same tests with different fixture instances. Also, you can directly declare the caching "scope" of fixtures so that dependent tests throughout your whole test suite can re-use database or other expensive fixture objects with ease. Lastly, it's possible for fixture functions (formerly known as funcarg factories) to use other fixtures, allowing for a completely modular and re-useable fixture design. For detailed info and tutorial-style examples, see: http://pytest.org/latest/fixture.html Moreover, there is now support for using pytest fixtures/funcargs with unittest-style suites, see here for examples: http://pytest.org/latest/unittest.html Besides, more unittest-test suites are now expected to "simply work" with pytest. All changes are backward compatible and you should be able to continue to run your test suites and 3rd party plugins that worked with pytest-2.2.4. If you are interested in the precise reasoning (including examples) of the pytest-2.3 fixture evolution, please consult http://pytest.org/latest/funcarg_compare.html For general info on installation and getting started: http://pytest.org/latest/getting-started.html Docs and PDF access as usual at: http://pytest.org and more details for those already in the knowing of pytest can be found in the CHANGELOG below. Particular thanks for this release go to Floris Bruynooghe, Alex Okrushko Carl Meyer, Ronny Pfannschmidt, Benjamin Peterson and Alex Gaynor for helping to get the new features right and well integrated. Ronny and Floris also helped to fix a number of bugs and yet more people helped by providing bug reports. have fun, holger krekel Changes between 2.2.4 and 2.3.0 ----------------------------------- - fix issue202 - better automatic names for parametrized test functions - fix issue139 - introduce @pytest.fixture which allows direct scoping and parametrization of funcarg factories. Introduce new @pytest.setup marker to allow the writing of setup functions which accept funcargs. - fix issue198 - conftest fixtures were not found on windows32 in some circumstances with nested directory structures due to path manipulation issues - fix issue193 skip test functions with were parametrized with empty parameter sets - fix python3.3 compat, mostly reporting bits that previously depended on dict ordering - introduce re-ordering of tests by resource and parametrization setup which takes precedence to the usual file-ordering - fix issue185 monkeypatching time.time does not cause pytest to fail - fix issue172 duplicate call of pytest.setup-decoratored setup_module functions - fix junitxml=path construction so that if tests change the current working directory and the path is a relative path it is constructed correctly from the original current working dir. - fix "python setup.py test" example to cause a proper "errno" return - fix issue165 - fix broken doc links and mention stackoverflow for FAQ - catch unicode-issues when writing failure representations to terminal to prevent the whole session from crashing - fix xfail/skip confusion: a skip-mark or an imperative pytest.skip will now take precedence before xfail-markers because we can't determine xfail/xpass status in case of a skip. see also: http://stackoverflow.com/questions/11105828/in-py-test-when-i-explicitly-sk… - always report installed 3rd party plugins in the header of a test run - fix issue160: a failing setup of an xfail-marked tests should be reported as xfail (not xpass) - fix issue128: show captured output when capsys/capfd are used - fix issue179: propperly show the dependency chain of factories - pluginmanager.register(...) now raises ValueError if the plugin has been already registered or the name is taken - fix issue159: improve http://pytest.org/latest/faq.html especially with respect to the "magic" history, also mention pytest-django, trial and unittest integration. - make request.keywords and node.keywords writable. All descendant collection nodes will see keyword values. Keywords are dictionaries containing markers and other info. - fix issue 178: xml binary escapes are now wrapped in py.xml.raw - fix issue 176: correctly catch the builtin AssertionError even when we replaced AssertionError with a subclass on the python level - factory discovery no longer fails with magic global callables that provide no sane __code__ object (mock.call for example) - fix issue 182: testdir.inprocess_run now considers passed plugins - fix issue 188: ensure sys.exc_info is clear on python2 before calling into a test - fix issue 191: add unittest TestCase runTest method support - fix issue 156: monkeypatch correctly handles class level descriptors - reporting refinements: - pytest_report_header now receives a "startdir" so that you can use startdir.bestrelpath(yourpath) to show nice relative path - allow plugins to implement both pytest_report_header and pytest_sessionstart (sessionstart is invoked first). - don't show deselected reason line if there is none - py.test -vv will show all of assert comparisations instead of truncating

ANN: v0.3 of pipe_controller released; supports swapping pipe components at run time
by vasudevram Oct. 17, 2012

Oct. 17, 2012

I've released v0.3 of pipe_controller (*), my experimental tool to simulate pipes in Python: https://bitbucket.org/vasudevram/pipe_controller (*) I had earlier been calling it PipeController, but that is the name of the main class in the package. From now on I'm referring to it as pipe_controller (the Python module name). Changes in v0.3: - you can now swap components of a pipe_controller pipe at run time, and it can separately save the results of running the pipe, before and after a component swap, to separate output files; the test program test_pipe_controller_04.py in the download package shows how to do this. That is, you can do something like this (using UNIX syntax, though pipe_controller is in Python and works differently): foo | bar | baz # with output going to file 1 then swap the positions of foo and baz, then run the pipe again: baz | bar | foo # with output going to file 2 and so on - any number of times, all in the same program run. This feature lets you experiment with, and validate, your pipeline logic, to make sure that it does what you intended, e.g. you can check the output both before and after swapping components of the pipe, to decide which order you really need - or which order is optimal - see next paragraph. The feature can also be used to time the execution of two or more different versions of the pipeline (with vs. without swapping of components), to see which runs faster, for cases where changing the order of those components makes no difference to the output, e.g. if those two components are commutative, in the mathematical sense (like a + b = b + a). Blog post about swapping pipe components at run time with pipe_controller: http://jugad2.blogspot.in/2012/10/swapping-pipe-components-at-runtime.html pipe_controller v0.3 can be downloaded here: https://bitbucket.org/vasudevram/pipe_controller/downloads (Click on the "Branches" tab on that page) - Vasudev Ram www.dancingbison.com jugad2.blogspot.com twitter.com/vasudevram

PyOpenGL 3.0.2 Released
by Mike C. Fletcher Oct. 15, 2012

Oct. 15, 2012

PyOpenGL 3.0.2 (final, finally) has been released. The major changes since 3.0.1 (released in 2010!) are: * OpenGL core support up to 4.3 level [1] * OpenGL extension support from the current registry [1] * Some missing FreeGLUT extensions added * OpenGL.GL.framebufferobjects providing ARB/EXT alternates for framebuffer operations * Experimental OSMesa (Offscreen Mesa) context (use the environment variable PYOPENGL_PLATFORM=osmesa) Codebase changes: * Experimental Python 3.2 and PyPy support * Win64 Support (including OpenGL_accelerate) * Numarray (the ancient transitional module between Numeric and numpy) is no longer supported as an array type * More compact auto-generated wrappers * Large numbers of bug fixes Downloads are at: http://pypi.python.org/pypi/PyOpenGL/3.0.2 http://pypi.python.org/pypi/PyOpenGL-accelerate/3.0.2 Future Compatibility Notes: * This will be the last release of PyOpenGL to support Python 2.5 (and it supports Python 2.5 in source-release only mode). o PyOpenGL will be moving to a "shared code" approach for Python 2/3 support, which makes supporting the older Python releases problematic * This will be the last release to support the use of bare numbers as number-array data-types o i.e. passing 1.00 to a function expecting an array/address of an float o Use Glfloat( 1.00 ) to pass in an array-compatible value o Passing in an int/long will generate a GLvoidp( I ) to allow for easy offset-address-style API usage * The ancient Numeric package (as distinct from Numpy) will be dropped as a supported array format o Numeric itself has long since been deprecated, use Numpy Enjoy all, Mike [1] Note: OpenGL extension and higher-level core feature support is auto-generated. As always, we are limited by the number of test programs that exercise more advanced features and the availability of hardware that can support the features on which to test -- ________________________________________________ Mike C.

[ANN] Automated Testing on Mac (ATOMac) 1.0.0 released
by James Tatum Oct. 12, 2012

Oct. 12, 2012

Hello, The ATOMac team is proud to announce a new release of ATOMac. About ATOMac: Short for Automated Testing on Mac, ATOMac is the first Python library to fully enable GUI testing of Macintosh applications via the Apple Accessibility API. Existing tools such as using appscript to send messages to accessibility objects are painful to write and slow to use. ATOMac has direct access to the API. It's fast and easy to use to write GUI tests. Changes in this release: * LDTP compatibility added. LDTP allows testers to write a single script that will automate test cases on Linux, Windows, and now Mac OS X. Information and documentation on LDTP can be found at the LDTP home page[0]. * Detailed documentation - Sphinx has been configured to generate documentation for ATOMac. When this documentation is uploaded, it will be linked from the home page[1]. * Various fixes to reading and writing certain accessibility attributes. * Sending function keys and newlines now works as intended. A detailed changelog is available[2]. Download source: https://github.com/pyatom/pyatom Documentation references: Sphinx documentation is being uploaded. In the meantime, please see the readme at the bottom of the github page listed above. Report bugs - https://github.com/pyatom/pyatom/issues To subscribe to ATOMac mailing lists, visit http://lists.pyatom.com/ IRC Channel - #atomac on irc.freenode.net [0] http://ldtp.freedesktop.org [1] http://pyatom.com/ [2] https://raw.github.com/pyatom/pyatom/master/CHANGELOG.txt
