Metadata-Version: 1.0 Name: discover Version: 0.4.0 Summary: Test discovery for unittest. Backported from Python 2.7 for Python 2.4+ Home-page: http://pypi.python.org/pypi/discover/ Author: Michael Foord Author-email: michael@voidspace.org.uk License: UNKNOWN Description: This is the test discovery mechanism and ``load_tests`` protocol for unittest backported from Python 2.7 to work with Python 2.4 or more recent (including Python 3). .. note:: Test discovery is just part of what is new in unittest in Python 2.7. All of the new features have been backported to run on Python 2.4-2.6, including test discovery. This is the `unittest2 package `_. discover can be installed with pip or easy_install. After installing switch the current directory to the top level directory of your project and run:: python -m discover python discover.py (If you have setuptools or `distribute `_ installed you will also have a ``discover`` script available.) This will discover all tests (with certain restrictions) from the current directory. The discover module has several options to control its behavior (full usage options are displayed with ``python -m discover -h``):: Usage: discover.py [options] Options: -v, --verbose Verbose output -s directory Directory to start discovery ('.' default) -p pattern Pattern to match test files ('test*.py' default) -t directory Top level directory of project (default to start directory) For test discovery all test modules must be importable from the top level directory of the project. For example to use a different pattern for matching test modules run:: python -m discover -p '*test.py' (For UNIX-like shells like Bash you need to put quotes around the test pattern or the shell will attempt to expand the pattern instead of passing it through to discover. On Windows you must *not* put quotes around the pattern as the Windows shell will pass the quotes to discover as well.) Test discovery is implemented in ``discover.DiscoveringTestLoader.discover``. As well as using discover as a command line script you can import ``DiscoveringTestLoader``, which is a subclass of ``unittest.TestLoader``, and use it in your test framework. This method finds and returns all test modules from the specified start directory, recursing into subdirectories to find them. Only test files that match *pattern* will be loaded. (Using shell style pattern matching.) All test modules must be importable from the top level of the project. If the start directory is not the top level directory then the top level directory must be specified separately. The ``load_tests`` protocol allows test modules and packages to customize how they are loaded. This is implemented in ``discover.DiscoveringTestLoader.loadTestsFromModule``. If a test module defines a ``load_tests`` function then tests are loaded from the module by calling ``load_tests`` with three arguments: `loader`, `standard_tests`, `None`. If a test package name (directory with `__init__.py`) matches the pattern then the package will be checked for a ``load_tests`` function. If this exists then it will be called with *loader*, *tests*, *pattern*. .. note:: The default pattern for matching tests is ``test*.py``. The '.py' means that it will match test files and *not* match package names. You can change this by changing the pattern using a command line option like ``-p 'test*'``. If ``load_tests`` exists then discovery does *not* recurse into the package, ``load_tests`` is responsible for loading all tests in the package. The pattern is deliberately not stored as a loader attribute so that packages can continue discovery themselves. *top_level_dir* is stored so ``load_tests`` does not need to pass this argument in to ``loader.discover()``. discover.py is maintained in a google code project (where bugs and feature requests should be posted): http://code.google.com/p/unittest-ext/ The latest development version of discover.py can be found at: http://code.google.com/p/unittest-ext/source/browse/trunk/discover.py CHANGELOG ========= 2010/06/11 0.4.0 ---------------- * Addition of a setuptools compatible test collector. Set "test_suite = 'discover.collector'" in setup.py. "setup.py test" will start test discovery with default parameters from the same directory as the setup.py. * Allow test discovery using dotted module names instead of a path. * Addition of a setuptools compatible entrypoint for the discover script. * A faulty load_tests function will not halt test discovery. A failing test is created to report the error. * If test discovery imports a module from the wrong location (usually because the module is globally installed and the user is expecting to run tests against a development version in a different location) then discovery halts with an ImportError and the problem is reported. * Matching files during test discovery is done in ``DiscoveringTestLoader._match_path``. This method can be overriden in subclasses to, for example, match on the full file path or use regular expressions for matching. * Tests for discovery ported from unittest2. (The tests require unittest2 to run.) Feature parity with the ``TestLoader`` in Python 2.7 RC 1. 2010/02/07 0.3.2 ---------------- * If ``load_tests`` exists it is passed the standard tests as a ``TestSuite`` rather than a list of tests. 2009/09/13 0.3.1 ---------------- * Fixed a problem when a package directory matches the discovery pattern. 2009/08/20 0.3.0 ---------------- * Failing to import a file (e.g. due to a syntax error) no longer halts discovery but is reported as a failure. * Discovery will not attempt to import test files whose names are not valid Python identifiers, even if they match the pattern.
