Mocker 0.9
by Gustavo Niemeyer 17 Nov '07

17 Nov '07

Greetings! Mocker 0.9 has just been released. The list of changes is provided below. Where ----- http://labix.org/mocker About ----- - Graceful platform for test doubles in Python (mocks, stubs, fakes, and dummies). - Inspiration from real needs, and also from pmock, jmock, pymock, easymock, etc. - Expectation of expressions defined by actually using mock objects. - Expressions may be replayed in any order by default, - Trivial specification of ordering between expressions when wanted. - Nice parameter matching for defining expectations on method calls. - Good error messages when expectations are broken. - Mocking of many kinds of expressions (getting/setting/deleting attributes, calling, iteration, containment, etc) - Graceful handling of nested expressions (e.g. "person.details.get_phone().get_prefix()") - Mock "proxies", which allow passing through to the real object on specified expressions (e.g. useful with "os.path.isfile()"). - Mocking via temporary "patching" of existent classes and instances. - Trivial mocking of any external module (e.g. "time.time()") via "proxy replacement". - Mock objects may have method calls checked for conformance with real class/instance to prevent API divergence. - Type simulation for using mocks while still performing certain type-checking operations. - Nice (optional) integration with "unittest.TestCase", including additional assertions (e.g. "assertIs", "assertIn", etc). - More ... Changes in 0.9 -------------- - Added MockerTestCase.makeFile() and .makeDir() helpers. They offer easy creation of temporary files/directories, and ensure that they get removed after each test method runs. - Added MockerTestCase.assertMethodsMatch(). It will verify if all public methods found in the class passed as the first argument are also present in the class passed as the second argument, and that they accept the same arguments. This is useful to verify if a fake or stub class have the same API as the real class being simulated. - Added MockerTestCase.assert[Not]{Starts,Ends}With(). - If the replay() method is called twice, expectations will be fully reset so that several similar tests may be performed in a row by just calling replay() again. - Mocker.on_restore() removed. Restore isn't performed if replay() isn't called, and that may not be obvious, so a hook won't be exposed for now. - When using a non-existent import path for Mocker.proxy(), raise an ImportError on the base module, rather than using the actual string as the object (#162315). -- Gustavo Niemeyer http://niemeyer.net

lockfile 0.2 - platform-independent advisory locks for Python
by skip＠pobox.com 17 Nov '07

17 Nov '07

I've released lockfile 0.2. Changes since the 0.1 release: * Added 2.4.diff file to patch lockfile to work with Python 2.4 (removes use of with statement). * Renamed _FileLock base class to LockBase to expose it (and its docstrings) to pydoc. * Got rid of time.sleep() calls in tests (thanks to Konstantin Veretennicov). * Use thread.get_ident() as the thread discriminator. * Updated documentation a bit. What is lockfile? ================= A number of implementations of file locks are out there, but as an exploration of the possibilities I wrote the lockfile module. It offers these features: * A platform-independent API * Three classes implementing file locks - LinkFileLock - relies on atomic nature of the link(2) system call. - MkdirFileLock - relies on atomic nature of the mkdir(2) systemm call. - SQLiteFileLock - provides locks through a SQLite database. * Locking is done on a per-thread basis by default, though locking can be done on a per-process basis instead. * Context manager support. The lockfile module is available from PyPI: http://pypi.python.org/pypi/lockfile/ I welcome feedback from anyone who gives it a whirl. The code is stored in a Mercurial repository on my laptop, so subject to occasional access problems when I'm on the train others are welcome to have access to the source code. If that's of interest to you, drop me a note. -- Skip Montanaro - skip(a)pobox.com - http://www.webfast.com/~skip/

Last chance for PyCon talk & tutorial proposals!
by David Goodger 15 Nov '07

15 Nov '07

Thanks to all the proposal authors so far, we have received lots of proposals for PyCon talks & tutorials. But we'd like to have even more. Alas, the proposal submission deadline should have been set after a weekend, not before. So we have decided to extend the proposal submission deadline to Monday, November 19 at midnight (Chicago time). This gives you a *whole extra weekend* to write up your talk and tutorial ideas! If you've been procrastinating, stop! Get started on a proposal instead! See the call for conference talk proposals: http://us.pycon.org/2008/conference/proposals/ Topic ideas: http://wiki.python.org/moin/Talk_Subjects http://wiki.python.org/moin/PyCon2007/Feedback#head-e2dca74d1492e49fae11550… See the call for tutorial proposals http://us.pycon.org/2008/tutorials/proposals/ Topic ideas from the PyCon 2007 feedback: http://wiki.python.org/moin/PyCon2007/Feedback/TutorialIdeas I hope to see (and hear) you at PyCon 2008! http://us.pycon.org -- David Goodger, PyCon 2008 Chair
