And thanks to Pam Zerbinos, it is much better organized and easier + to use and read. +- Two new core commandline options can help with testing namespace + packages. :option:`--first-package-wins` is useful when you want to test one + part of a namespace package that uses another part; in previous versions of + nose, the other part of the namespace package would be evicted from + sys.modules when the 2nd loaded. :option:`--traverse-namespace` is useful if + you want nose to discover tests across entries in a package's + __path__.

When this option is in effect, if + any tests failed in the previous test run (so long as testid was active for + that test run) only the failed tests will run. +- Made it possible to 'yield test' in addition to 'yield test,' from test + generators. Thanks to Chad Whitacre for the patch (#230). +- Fixed bug that caused traceback inspector to fail when source code file + could not be found. Thanks to Philip Jenvey for the bug report and patch + (#236). +- Fixed some issues limiting compatibility with IronPython. Thanks to Kevin + Mitchell for the patch. +- Added support for module and test case fixtures in doctest files (#60). +- Added --traverse-namespace commandline option that restores old default + behavior of following all package __path__ entries when loading tests from + packages.

Thanks to Philip Jenvey for the bug report (#191). +- Raised score of coverage plugin to 200, so that it will execute before + default-score plugins, and so be able to catch more import-time code. Thanks + to Ned Batchelder for the bug report and patch (#190). + +0.10.2 + +- nose now runs under jython (jython svn trunk only at this time). Thanks to + Philip Jenvey, Pam Zerbinos and the other pycon sprinters (#160). +- Fixed bugs in loader, default plugin manager, and other modules that + caused plugin exceptions to be swallowed (#152, #155). Thanks to John J + Lee for the bug report and patch. +- Added selftest.py script, used to test a non-installed distribution of + nose (#49).

Plugins always see instances of this class. +- Added a management layer to the plugin system, allowing for easy use + of different plugin loading schemes. The default manager loads + builtin plugins, 0.10 plugins under the setuptools entrypoint + nose.plugins.0-10 and provides limited support for legacy plugins + loaded under the entrypoint nose.plugins. +- Added plugin hooks in all phases of discovery, running and description. +- Converted several formely core features to plugins: output capture, + assert introspection, pdb, and skipped and deprecated test support. +- Added id plugin that allows for easier specification of tests on the + command line. +- Added ErrorClassPlugin base class to allow for easier authoring of + plugins that handle errors, like the builtin skipped and deprecated + test plugins. +- Added support for loading doctests from non-module files for all + supported python versions. +- Added score property to plugins to allow plugins to execute in a + defined order (higher score execute first). +- Expanded nose's own test suite to include a variety of functional tests. +- Fixed many bugs. + +0.9.3 + +- Added support for user configuration files.

Used to construct decorator + functions that are well-behaved and preserve as much of the original + function's metadata as possible. Thanks to Antoine Pitrou for the patch. +- Added nose.twistedtools, contributed by Antoine Pitrou. This module adds + @deferred decorator that makes it simple to write deferred tests, with or + without timeouts. +- Added monkeypatch to doctests that keeps doctest from stepping on coverage + when the two plugins are used together. Thanks to David Avraamides for the + bug report. +- Added isolation plugin. Use this plugin to automatically restore sys.modules + after each test module or package.

Thanks to Jason Hildebrand for the patch. +- Improved compatibility with python 2.2. Thanks to Chad Whitacre for the + patch. +- Fixed bug in handling of options from setup.cfg. Thanks to Kumar McMillan for + the patch. +- Fixed bug in generator methods, where a generator method using an inline + funciton would result in an AttributeError. Thanks to Antoine Pitrou for the + bug report. +- Updated coverage plugin to ignore lines tagged with #pragma: no cover, + matching the behavior of coverage.py on the command line. Thanks to Bill + Zingler for the bug report. +- Added a man page for nosetests. Thanks to Gustavo Noronha Silva for the + request and providing an example. + +0.9.1 + +- New function nose.runmodule() finds and runs tests only in a + single module, which defaults to __main__ (like unittest.main() or + doctest.runmodule()). Thanks Greg Wilson for the suggestion. +- Multiple -w (--where) arguments can now be used in one command line, + to find and run tests in multiple locations. Thanks Titus Brown for + the suggestion. +- Multiple --include and --exclude arguments are now accepted in one command + line. Thanks Michal Kwiatkowski for the feature request. +- Coverage will now include modules not imported by any test when + using the new --cover-inclusive switch. Thanks James Casbon for the + patch. +- module:TestClass test selections now properly select all tests in the test + class. +- startTest and stopTest are now called in plugins at the beginning and end of + test suites, including test modules, as well as individual tests. Thanks + Michal Kwiatkowski for the suggestion. +- Fix bug in test selection when run as ``python setup.py test``: 'test' was + passing through and being used as the test name selection. Thanks Kumar + McMillan for the bug report. +- Fix bug in handling of -x/--stop option where the test run would stop on + skipped or deprecated tests. Thanks Kumar McMillan for the bug report. +- Fix bug in loading tests from projects with layouts that place modules in + /lib or /src dirs and tests in a parallel /tests dir. +- Fix bug in python version detection. Thanks Kevin Dangoor for the bug report + and fix. +- Fix log message in selector that could raise IndexError. Thanks Kumar + McMillan for the bug report and patch. +- Fix bug in handling doctest extension arguments specified in environment and + on command line. Thanks Ian Bicking for the bug report. +- Fix bug in running fixtures (setup/teardown) that are not functions, and + report a better error message when a fixture is not callable. Thanks Ian + Bicking for the bug report. + +0.9.0 + +- More unit tests and better test coverage. Numerous bugfixes deriving from + same. +- Make --exe option do what it says, and turn it on by default on + Windows. Add --noexe option so windows users can turn if off.Thanks + richard at artsalliancemedia dot com for the bug reports. +- Handle a working directory that happens to be in the middle of a package + more gracefully. Thanks Max Ischenko for the bug report and test case. +- Fix bugs in test name comparison when a test module is specified whose name + overlaps that of a non-test module.

These are standard .ini-style config files. Put your +nosetests configuration in a [nosetests] section, with the -- prefix +removed: + + [nosetests] + verbosity=3 + with-doctest=1 + +There are several other ways to use the nose test runner besides the +*nosetests* script. You may use nose in a test script: + + import nose + nose.main() + +If you don't want the test script to exit with 0 on success and 1 on +failure (like unittest.main), use nose.run() instead: + + import nose + result = nose.run() + +*result* will be true if the test run succeeded, or false if any test +failed or raised an uncaught exception. Lastly, you can run nose.core +directly, which will run nose.main(): + + python /path/to/nose/core.py + +Please see the usage message for the nosetests script for information +about how to control which tests nose runs, which plugins are loaded, +and the test output. + + +Extended usage +============== + +nose collects tests automatically from python source files, +directories and packages found in its working directory (which +defaults to the current working directory). Any python source file, +directory or package that matches the testMatch regular expression (by +default: *(?:^|[b_.-])[Tt]est)* will be collected as a test (or source +for collection of tests). In addition, all other packages found in the +working directory will be examined for python source files or +directories that match testMatch. Package discovery descends all the +way down the tree, so package.tests and package.sub.tests and +package.sub.sub2.tests will all be collected. + +Within a test directory or package, any python source file matching +testMatch will be examined for test cases. Within a test module, +functions and classes whose names match testMatch and TestCase +subclasses with any name will be loaded and executed as tests. Tests +may use the assert keyword or raise AssertionErrors to indicate test +failure. TestCase subclasses may do the same or use the various +TestCase methods available. + + +Selecting Tests +--------------- + +To specify which tests to run, pass test names on the command line: + + nosetests only_test_this.py + +Test names specified may be file or module names, and may optionally +indicate the test case to run by separating the module or file name +from the test case name with a colon. Filenames may be relative or +absolute. Examples: + + nosetests test.module + nosetests another.test:TestCase.test_method + nosetests a.test:TestCase + nosetests /path/to/test/file.py:test_function + +You may also change the working directory where nose looks for tests +by using the -w switch: + + nosetests -w /path/to/tests + +Note, however, that support for multiple -w arguments is now +deprecated and will be removed in a future release. As of nose 0.10, +you can get the same behavior by specifying the target directories +*without* the -w switch: + + nosetests /path/to/tests /another/path/to/tests + +Further customization of test selection and loading is possible +through the use of plugins. + +Test result output is identical to that of unittest, except for the +additional features (error classes, and plugin-supplied features such +as output capture and assert introspection) detailed in the options +below. + + +Configuration +------------- + +In addition to passing command-line options, you may also put +configuration options in your project's *setup.cfg* file, or a .noserc +or nose.cfg file in your home directory. In any of these standard +.ini-style config files, you put your nosetests configuration in a +"[nosetests]" section. Options are the same as on the command line, +with the -- prefix removed. For options that are simple switches, you +must supply a value: + + [nosetests] + verbosity=3 + with-doctest=1 + +All configuration files that are found will be loaded and their +options combined. You can override the standard config file loading +with the "-c" option. + + +Using Plugins +------------- + +There are numerous nose plugins available via easy_install and +elsewhere. To use a plugin, just install it. The plugin will add +command line options to nosetests. To verify that the plugin is +installed, run: + + nosetests --plugins + +You can add -v or -vv to that command to show more information about +each plugin. + +If you are running nose.main() or nose.run() from a script, you can +specify a list of plugins to use by passing a list of plugins with the +plugins keyword argument. + + +0.9 plugins +----------- + +nose 1.0 can use SOME plugins that were written for nose 0.9. The +default plugin manager inserts a compatibility wrapper around 0.9 +plugins that adapts the changed plugin api calls. However, plugins +that access nose internals are likely to fail, especially if they +attempt to access test case or test suite classes. For example, +plugins that try to determine if a test passed to startTest is an +individual test or a suite will fail, partly because suites are no +longer passed to startTest and partly because it's likely that the +plugin is trying to find out if the test is an instance of a class +that no longer exists. + + +0.10 and 0.11 plugins +--------------------- + +All plugins written for nose 0.10 and 0.11 should work with nose 1.0. + + +Options +------- + +-V, --version + + Output nose version and exit + +-p, --plugins + + Output list of available plugins and exit.

Please note +that they *must not* subclass `IPluginInterface`; `IPluginInterface` is only a +description of the plugin API. + +When plugins are called, the first plugin that implements a method and returns +a non-None value wins, and plugin processing ends. The exceptions to this are +methods marked as `generative` or `chainable`. `generative` methods combine +the output of all plugins that respond with an iterable into a single +flattened iterable response (a generator, really). `chainable` methods pass +the results of calling plugin A as the input to plugin B, where the positions +in the chain are determined by the plugin sort order, which is in order by +`score` descending. + +In general, plugin methods correspond directly to methods of +`nose.selector.Selector`, `nose.loader.TestLoader` and +`nose.result.TextTestResult` are called by those methods when they are +called. In some cases, the plugin hook doesn't neatly match the method in +which it is called; for those, the documentation for the hook will tell you +where in the test process it is called. + +Plugin hooks fall into four broad categories: selecting and loading tests, +handling errors raised by tests, preparing objects used in the testing +process, and watching and reporting on test results. + +Selecting and loading tests +^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +To alter test selection behavior, implement any necessary `want*` methods as +outlined below. Keep in mind, though, that when your plugin returns True from +a `want*` method, you will send the requested object through the normal test +collection process. If the object represents something from which normal tests +can't be collected, you must also implement a loader method to load the tests. + +Examples: + +* The builtin :doc:`doctests plugin ` implements `wantFile` to + enable loading of doctests from files that are not python modules. It + also implements `loadTestsFromModule` to load doctests from + python modules, and `loadTestsFromFile` to load tests from the + non-module files selected by `wantFile`. + +* The builtin :doc:`attrib plugin ` implements `wantFunction` and + `wantMethod` so that it can reject tests that don't match the + specified attributes. + +Handling errors +^^^^^^^^^^^^^^^ + +To alter error handling behavior -- for instance to catch a certain class of +exception and handle it differently from the normal error or failure handling +-- you should subclass :class:`nose.plugins.errorclass.ErrorClassPlugin`. See +:doc:`the section on ErrorClass plugins ` for more details. + +Examples: + +* The builtin :doc:`skip ` and :doc:`deprecated ` plugins are + ErrorClass plugins. + + +Preparing test objects +^^^^^^^^^^^^^^^^^^^^^^ + +To alter, get a handle on, or replace test framework objects such as the +loader, result, runner, and test cases, use the appropriate prepare methods. +The simplest reason to use prepare is in the case that you need to use an +object yourself. For example, the isolate plugin implements `prepareTestLoader` +so that it can use the loader later on to load tests. If you return a value +from a prepare method, that value will be used in place of the loader, result, +runner or test case, depending on which prepare method you use. Be aware that +when replacing test cases, you are replacing the *entire* test case -- including +the whole `run(result)` method of the `unittest.TestCase` -- so if you want +normal unittest test result reporting, you must implement the same calls to +result as `unittest.TestCase.run`. + +Examples: + +* The builtin :doc:`isolate plugin ` implements `prepareTestLoader` + but does not replace the test loader. + +* The builtin :doc:`profile plugin ` implements `prepareTest` and does + replace the top-level test case by returning the case wrapped in + the profiler function. + +Watching or reporting on tests +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +To record information about tests or other modules imported during +the testing process, output additional reports, or entirely change +test report output, implement any of the methods outlined below that +correspond to TextTestResult methods. + +Examples: + +* The builtin :doc:`cover plugin ` implements `begin` and `report` to + capture and report code coverage metrics for all or selected modules + loaded during testing. + +* The builtin :doc:`profile plugin ` implements `begin`, `prepareTest` + and `report` to record and output profiling information.

It also comes with plugin hooks for loading, running, watching and +reporting on tests and test runs. If you don't like the default collection +scheme, or it doesn't suit the layout of your project, or you need reports in +a format different from the unittest standard, or you need to collect some +additional information about tests (like code coverage or profiling data), you +can write a plugin to make nose do what you want.

For the sake +of compatibility with legacy unittest test cases, nose will also load tests +from :class:`unittest.TestCase` subclasses just like unittest does. Like +py.test, nose runs functional tests in the order in which they appear in the +module file. TestCase-derived tests and other test classes are run in +alphabetical order. + +.. _py.test: http://codespeak.net/py/current/doc/test.html + +.. _fixtures: + +Fixtures +======== + +nose supports fixtures (setup and teardown methods) at the package, +module, class, and test level. As with py.test or unittest fixtures, +setup always runs before any test (or collection of tests for test +packages and modules); teardown runs if setup has completed +successfully, regardless of the status of the test run. For more detail +on fixtures at each level, see below. + +Test packages +============= + +nose allows tests to be grouped into test packages. This allows +package-level setup; for instance, if you need to create a test database +or other data fixture for your tests, you may create it in package setup +and remove it in package teardown once per test run, rather than having to +create and tear it down once per test module or test case. + +To create package-level setup and teardown methods, define setup and/or +teardown functions in the ``__init__.py`` of a test package. Setup methods may +be named `setup`, `setup_package`, `setUp`, or `setUpPackage`; teardown may +be named `teardown`, `teardown_package`, `tearDown` or `tearDownPackage`. +Execution of tests in a test package begins as soon as the first test +module is loaded from the test package. + +Test modules +============ + +A test module is a python module that matches the testMatch regular +expression. Test modules offer module-level setup and teardown; define the +method `setup`, `setup_module`, `setUp` or `setUpModule` for setup, +`teardown`, `teardown_module`, or `tearDownModule` for teardown. Execution +of tests in a test module begins after all tests are collected. + +Test classes +============ + +A test class is a class defined in a test module that matches testMatch or is +a subclass of :class:`unittest.TestCase`. All test classes are run the same +way: Methods in the class that match testMatch are discovered, and a test +case is constructed to run each method with a fresh instance of the test +class. Like :class:`unittest.TestCase` subclasses, other test classes can +define setUp and tearDown methods that will be run before and after each test +method. Test classes that do not descend from `unittest.TestCase` may also +include generator methods and class-level fixtures. Class-level setup fixtures +may be named `setup_class`, `setupClass`, `setUpClass`, `setupAll` or +`setUpAll`; teardown fixtures may be named `teardown_class`, `teardownClass`, +`tearDownClass`, `teardownAll` or `tearDownAll`. Class-level setup and teardown +fixtures must be class methods. + +Test functions +============== + +Any function in a test module that matches testMatch will be wrapped in a +`FunctionTestCase` and run as a test. The simplest possible failing test is +therefore:: + + def test(): + assert False + +And the simplest passing test:: + + def test(): + pass + +Test functions may define setup and/or teardown attributes, which will be +run before and after the test function, respectively. A convenient way to +do this, especially when several test functions in the same module need +the same setup, is to use the provided `with_setup` decorator:: + + def setup_func(): + "set up test fixtures" + + def teardown_func(): + "tear down test fixtures" + + @with_setup(setup_func, teardown_func) + def test(): + "test ..." + +For python 2.3 or earlier, add the attributes by calling the decorator +function like so:: + + def test(): + "test ... " + test = with_setup(setup_func, teardown_func)(test) + +or by direct assignment:: + + test.setup = setup_func + test.teardown = teardown_func + +Please note that `with_setup` is useful *only* for test functions, not +for test methods in `unittest.TestCase` subclasses or other test +classes. For those cases, define `setUp` and `tearDown` methods in the +class. + +Test generators +=============== + +nose supports test functions and methods that are generators. A simple +example from nose's selftest suite is probably the best explanation:: + + def test_evens(): + for i in range(0, 5): + yield check_even, i, i*3 + + def check_even(n, nn): + assert n % 2 == 0 or nn % 2 == 0 + +This will result in five tests. nose will iterate the generator, creating a +function test case wrapper for each tuple it yields. As in the example, test +generators must yield tuples, the first element of which must be a callable +and the remaining elements the arguments to be passed to the callable. + +By default, the test name output for a generated test in verbose mode +will be the name of the generator function or method, followed by the +args passed to the yielded callable. If you want to show a different test +name, set the ``description`` attribute of the yielded callable. + +Setup and teardown functions may be used with test generators. However, please +note that setup and teardown attributes attached to the *generator function* +will execute only once. To *execute fixtures for each yielded test*, attach +the setup and teardown attributes to the function that is yielded, or yield a +callable object instance with setup and teardown attributes. + +For example:: + + @with_setup(setup_func, teardown_func) + def test_generator(): + # ... + yield func, arg, arg # ... + +Here, the setup and teardown functions will be executed *once*. Compare to:: + + def test_generator(): + # ... + yield func, arg, arg # ... + + @with_setup(setup_func, teardown_func) + def func(arg): + assert something_about(arg) + +In the latter case the setup and teardown functions will execute once for each +yielded test. + +For generator methods, the setUp and tearDown methods of the class (if any) +will be run before and after each generated test case. The setUp and tearDown +methods *do not* run before the generator method itself, as this would cause +setUp to run twice before the first test without an intervening tearDown. + +Please note that method generators *are not* supported in `unittest.TestCase` +subclasses. \ No newline at end of file diff --git a/examples/attrib_plugin.py b/examples/attrib_plugin.py new file mode 100644 index 0000000..c1f8458 --- /dev/null +++ b/examples/attrib_plugin.py @@ -0,0 +1,82 @@ +""" +Examples of test function/method attribute usage with patched nose + +Simple syntax (-a, --attr) examples: + * nosetests -a status=stable + => only test cases with attribute "status" having value "stable" + + * nosetests -a priority=2,status=stable + => both attributes must match + + * nosetests -a tags=http + => attribute list "tags" must contain value "http" (see test_foobar() + below for definition) + + * nosetests -a slow + => attribute "slow" must be defined and its value cannot equal to False + (False, [], "", etc...) + + * nosetests -a !slow + => attribute "slow" must NOT be defined or its value must be equal to False + +Eval expression syntax (-A, --eval-attr) examples: + * nosetests -A "not slow" + * nosetests -A "(priority > 5) and not slow" + +This example and the accompanied patch is in public domain, free for any use. + +email: mika.eloranta@gmail.com + +""" + +__author__ = 'Mika Eloranta' + +def attr(**kwargs): + """Add attributes to a test function/method/class""" + def wrap(func): + func.__dict__.update(kwargs) + return func + return wrap + +# test function with single attribute +@attr(priority = 1) +def test_dummy(): + print "dummy" + +# test function with multiple attributes +@attr(status = "stable", # simple string attribute + slow = True, # attributes can be of any type + # (e.g. bool) + priority = 1, # ...or int + tags = ["http", "pop", "imap"]) # will be run if any of the list items + # matches +def test_foobar(): + print "foobar" + +# another way of adding attributes... +def test_fluffy(): + print "fluffy" +test_fluffy.status = "unstable" +test_fluffy.slow = True +test_fluffy.priority = 2 + +# works for class methods, too +class TestSomething: + @attr(status = "stable", priority = 2) + def test_xyz(self): + print "xyz" + +# class methods "inherit" attributes from the class but can override them +class TestOverride: + value = "class" + # run all methods with "nosetests -a value" + + @attr(value = "method") + def test_override(self): + # run with "nosetests -a value=method" + print "override" + + def test_inherit(self): + # run with "nosetests -a value=class" + print "inherit" + diff --git a/examples/html_plugin/htmlplug.py b/examples/html_plugin/htmlplug.py new file mode 100644 index 0000000..aa1bcb6 --- /dev/null +++ b/examples/html_plugin/htmlplug.py @@ -0,0 +1,92 @@ +"""This is a very basic example of a plugin that controls all test +output.

Note :: + + Use of the multiprocess plugin on python 2.5 or earlier requires + the multiprocessing_ module, available from PyPI and at + http://code.google.com/p/python-multiprocessing/. + +.. + +Using the `nose.plugin.multiprocess` plugin, you can parallelize a +test run across a configurable number of worker processes. While this can +speed up CPU-bound test runs, it is mainly useful for IO-bound tests +that spend most of their time waiting for data to arrive from someplace +else and can benefit from parallelization. + +.. _multiprocessing : http://code.google.com/p/python-multiprocessing/ + +How tests are distributed +========================= + +The ideal case would be to dispatch each test to a worker process separately, +and to have enough worker processes that the entire test run takes only as +long as the slowest test. This ideal is not attainable in all cases, however, +because many test suites depend on context (class, module or package) +fixtures. + +Some context fixtures are re-entrant -- that is, they can be called many times +concurrently. Other context fixtures can be shared among tests running in +different processes. Still others must be run once and only once for a given +set of tests, and must be in the same process as the tests themselves. + +The plugin can't know the difference between these types of context fixtures +unless you tell it, so the default behavior is to dispatch the entire context +suite to a worker as a unit. This way, the fixtures are run once, in the same +process as the tests. (That, of course, is how they are run when the plugin +is not active: All tests are run in a single process.) + +Controlling distribution +^^^^^^^^^^^^^^^^^^^^^^^^ + +There are two context-level variables that you can use to control this default +behavior. + +If a context's fixtures are re-entrant, set ``_multiprocess_can_split_ = True`` +in the context, and the plugin will dispatch tests in suites bound to that +context as if the context had no fixtures. This means that the fixtures will +execute multiple times, typically once per test, and concurrently. + +For example, a module that contains re-entrant fixtures might look like:: + + _multiprocess_can_split_ = True + + def setup(): + ... + +A class might look like:: + + class TestClass: + _multiprocess_can_split_ = True + + @classmethod + def setup_class(cls): + ... + +Alternatively, if a context's fixtures may only be run once, or may not run +concurrently, but *may* be shared by tests running in different processes +-- for instance a package-level fixture that starts an external http server or +initializes a shared database -- then set ``_multiprocess_shared_ = True`` in +the context. Fixtures for contexts so marked will execute in the primary nose +process, and tests in those contexts will be individually dispatched to run in +parallel. + +A module with shareable fixtures might look like:: + + _multiprocess_shared_ = True + + def setup(): + ... + +A class might look like:: + + class TestClass: + _multiprocess_shared_ = True + + @classmethod + def setup_class(cls): + ... + +These options are mutually exclusive: you can't mark a context as both +splittable and shareable. + +Example +~~~~~~~ + +Consider three versions of the same test suite.

However, there +are a few other differences that may impact your test suite: + +* More tests may be found + + Because tests are dispatched to worker processes by name, a worker + process may find and run tests in a module that would not be found during a + normal test run. For instance, if a non-test module contains a test-like + function, that function would be discovered as a test in a worker process + if the entire module is dispatched to the worker. This is because worker + processes load tests in *directed* mode -- the same way that nose loads + tests when you explicitly name a module -- rather than in *discovered* mode, + the mode nose uses when looking for tests in a directory. + +* Out-of-order output + + Test results are collected by workers and returned to the master process for + output. Since different processes may complete their tests at different + times, test result output order is not determinate. + +* Plugin interaction warning + + The multiprocess plugin does not work well with other plugins that expect to + wrap or gain control of the test-running process. Examples from nose's + builtin plugins include coverage and profiling: a test run using + both multiprocess and either of those is likely to fail in some + confusing and spectacular way. + +* Python 2.6 warning + + This is unlikely to impact you unless you are writing tests for nose itself, + but be aware that under python 2.6, the multiprocess plugin is not + re-entrant. For example, when running nose with the plugin active, you can't + use subprocess to launch another copy of nose that also uses the + multiprocess plugin. This is why this test is skipped under python 2.6 when + run with the ``--processes`` switch. diff --git a/functional_tests/doc_tests/test_multiprocess/multiprocess_fixtures.py b/functional_tests/doc_tests/test_multiprocess/multiprocess_fixtures.py new file mode 100644 index 0000000..8b4c3af --- /dev/null +++ b/functional_tests/doc_tests/test_multiprocess/multiprocess_fixtures.py @@ -0,0 +1,16 @@ +from nose.plugins.skip import SkipTest +from nose.plugins.multiprocess import MultiProcess + +_multiprocess_can_split_ = True + +def setup_module(): + try: + import multiprocessing + if 'active' in MultiProcess.status: + raise SkipTest("Multiprocess plugin is active.

It also counts + as the successor of the GNU Library Public License, version 2, hence + the version number 2.1.] + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +Licenses are intended to guarantee your freedom to share and change +free software--to make sure the software is free for all its users. + + This license, the Lesser General Public License, applies to some +specially designated software packages--typically libraries--of the +Free Software Foundation and other authors who decide to use it. You +can use it too, but we suggest you first think carefully about whether +this license or the ordinary General Public License is the better +strategy to use in any particular case, based on the explanations below. + + When we speak of free software, we are referring to freedom of use, +not price. Our General Public Licenses are designed to make sure that +you have the freedom to distribute copies of free software (and charge +for this service if you wish); that you receive source code or can get +it if you want it; that you can change the software and use pieces of +it in new free programs; and that you are informed that you can do +these things. + + To protect your rights, we need to make restrictions that forbid +distributors to deny you these rights or to ask you to surrender these +rights. These restrictions translate to certain responsibilities for +you if you distribute copies of the library or if you modify it. + + For example, if you distribute copies of the library, whether gratis +or for a fee, you must give the recipients all the rights that we gave +you. You must make sure that they, too, receive or can get the source +code. If you link other code with the library, you must provide +complete object files to the recipients, so that they can relink them +with the library after making changes to the library and recompiling +it. And you must show them these terms so they know their rights. + + We protect your rights with a two-step method: (1) we copyright the +library, and (2) we offer you this license, which gives you legal +permission to copy, distribute and/or modify the library. + + To protect each distributor, we want to make it very clear that +there is no warranty for the free library. Also, if the library is +modified by someone else and passed on, the recipients should know +that what they have is not the original version, so that the original +author's reputation will not be affected by problems that might be +introduced by others. + + Finally, software patents pose a constant threat to the existence of +any free program. We wish to make sure that a company cannot +effectively restrict the users of a free program by obtaining a +restrictive license from a patent holder. Therefore, we insist that +any patent license obtained for a version of the library must be +consistent with the full freedom of use specified in this license. + + Most GNU software, including some libraries, is covered by the +ordinary GNU General Public License. This license, the GNU Lesser +General Public License, applies to certain designated libraries, and +is quite different from the ordinary General Public License. We use +this license for certain libraries in order to permit linking those +libraries into non-free programs. + + When a program is linked with a library, whether statically or using +a shared library, the combination of the two is legally speaking a +combined work, a derivative of the original library. The ordinary +General Public License therefore permits such linking only if the +entire combination fits its criteria of freedom. The Lesser General +Public License permits more lax criteria for linking other code with +the library. + + We call this license the "Lesser" General Public License because it +does Less to protect the user's freedom than the ordinary General +Public License. It also provides other free software developers Less +of an advantage over competing non-free programs. These disadvantages +are the reason we use the ordinary General Public License for many +libraries. However, the Lesser license provides advantages in certain +special circumstances. + + For example, on rare occasions, there may be a special need to +encourage the widest possible use of a certain library, so that it becomes +a de-facto standard. To achieve this, non-free programs must be +allowed to use the library. A more frequent case is that a free +library does the same job as widely used non-free libraries. In this +case, there is little to gain by limiting the free library to free +software only, so we use the Lesser General Public License. + + In other cases, permission to use a particular library in non-free +programs enables a greater number of people to use a large body of +free software. For example, permission to use the GNU C Library in +non-free programs enables many more people to use the whole GNU +operating system, as well as its variant, the GNU/Linux operating +system. + + Although the Lesser General Public License is Less protective of the +users' freedom, it does ensure that the user of a program that is +linked with the Library has the freedom and the wherewithal to run +that program using a modified version of the Library. + + The precise terms and conditions for copying, distribution and +modification follow. Pay close attention to the difference between a +"work based on the library" and a "work that uses the library". The +former contains code derived from the library, whereas the latter must +be combined with the library in order to run. + + GNU LESSER GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License Agreement applies to any software library or other +program which contains a notice placed by the copyright holder or +other authorized party saying it may be distributed under the terms of +this Lesser General Public License (also called "this License"). +Each licensee is addressed as "you". + + A "library" means a collection of software functions and/or data +prepared so as to be conveniently linked with application programs +(which use some of those functions and data) to form executables. + + The "Library", below, refers to any such software library or work +which has been distributed under these terms. A "work based on the +Library" means either the Library or any derivative work under +copyright law: that is to say, a work containing the Library or a +portion of it, either verbatim or with modifications and/or translated +straightforwardly into another language. (Hereinafter, translation is +included without limitation in the term "modification".) + + "Source code" for a work means the preferred form of the work for +making modifications to it. For a library, complete source code means +all the source code for all modules it contains, plus any associated +interface definition files, plus the scripts used to control compilation +and installation of the library. + + Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running a program using the Library is not restricted, and output from +such a program is covered only if its contents constitute a work based +on the Library (independent of the use of the Library in a tool for +writing it). Whether that is true depends on what the Library does +and what the program that uses the Library does. + + 1. You may copy and distribute verbatim copies of the Library's +complete source code as you receive it, in any medium, provided that +you conspicuously and appropriately publish on each copy an +appropriate copyright notice and disclaimer of warranty; keep intact +all the notices that refer to this License and to the absence of any +warranty; and distribute a copy of this License along with the +Library. + + You may charge a fee for the physical act of transferring a copy, +and you may at your option offer warranty protection in exchange for a +fee. + + 2. You may modify your copy or copies of the Library or any portion +of it, thus forming a work based on the Library, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) The modified work must itself be a software library. + + b) You must cause the files modified to carry prominent notices + stating that you changed the files and the date of any change. + + c) You must cause the whole of the work to be licensed at no + charge to all third parties under the terms of this License. + + d) If a facility in the modified Library refers to a function or a + table of data to be supplied by an application program that uses + the facility, other than as an argument passed when the facility + is invoked, then you must make a good faith effort to ensure that, + in the event an application does not supply such function or + table, the facility still operates, and performs whatever part of + its purpose remains meaningful. + + (For example, a function in a library to compute square roots has + a purpose that is entirely well-defined independent of the + application. Therefore, Subsection 2d requires that any + application-supplied function or table used by this function must + be optional: if the application does not supply it, the square + root function must still compute square roots.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Library, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Library, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote +it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Library. + +In addition, mere aggregation of another work not based on the Library +with the Library (or with a work based on the Library) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may opt to apply the terms of the ordinary GNU General Public +License instead of this License to a given copy of the Library. To do +this, you must alter all the notices that refer to this License, so +that they refer to the ordinary GNU General Public License, version 2, +instead of to this License. (If a newer version than version 2 of the +ordinary GNU General Public License has appeared, then you can specify +that version instead if you wish.) Do not make any other change in +these notices. + + Once this change is made in a given copy, it is irreversible for +that copy, so the ordinary GNU General Public License applies to all +subsequent copies and derivative works made from that copy. + + This option is useful when you wish to copy part of the code of +the Library into a program that is not a library. + + 4. You may copy and distribute the Library (or a portion or +derivative of it, under Section 2) in object code or executable form +under the terms of Sections 1 and 2 above provided that you accompany +it with the complete corresponding machine-readable source code, which +must be distributed under the terms of Sections 1 and 2 above on a +medium customarily used for software interchange. + + If distribution of object code is made by offering access to copy +from a designated place, then offering equivalent access to copy the +source code from the same place satisfies the requirement to +distribute the source code, even though third parties are not +compelled to copy the source along with the object code. + + 5. A program that contains no derivative of any portion of the +Library, but is designed to work with the Library by being compiled or +linked with it, is called a "work that uses the Library". Such a +work, in isolation, is not a derivative work of the Library, and +therefore falls outside the scope of this License. + + However, linking a "work that uses the Library" with the Library +creates an executable that is a derivative of the Library (because it +contains portions of the Library), rather than a "work that uses the +library". The executable is therefore covered by this License. +Section 6 states terms for distribution of such executables. + + When a "work that uses the Library" uses material from a header file +that is part of the Library, the object code for the work may be a +derivative work of the Library even though the source code is not. +Whether this is true is especially significant if the work can be +linked without the Library, or if the work is itself a library. The +threshold for this to be true is not precisely defined by law. + + If such an object file uses only numerical parameters, data +structure layouts and accessors, and small macros and small inline +functions (ten lines or less in length), then the use of the object +file is unrestricted, regardless of whether it is legally a derivative +work. (Executables containing this object code plus portions of the +Library will still fall under Section 6.) + + Otherwise, if the work is a derivative of the Library, you may +distribute the object code for the work under the terms of Section 6. +Any executables containing that work also fall under Section 6, +whether or not they are linked directly with the Library itself. + + 6. As an exception to the Sections above, you may also combine or +link a "work that uses the Library" with the Library to produce a +work containing portions of the Library, and distribute that work +under terms of your choice, provided that the terms permit +modification of the work for the customer's own use and reverse +engineering for debugging such modifications. + + You must give prominent notice with each copy of the work that the +Library is used in it and that the Library and its use are covered by +this License. You must supply a copy of this License. If the work +during execution displays copyright notices, you must include the +copyright notice for the Library among them, as well as a reference +directing the user to the copy of this License. Also, you must do one +of these things: + + a) Accompany the work with the complete corresponding + machine-readable source code for the Library including whatever + changes were used in the work (which must be distributed under + Sections 1 and 2 above); and, if the work is an executable linked + with the Library, with the complete machine-readable "work that + uses the Library", as object code and/or source code, so that the + user can modify the Library and then relink to produce a modified + executable containing the modified Library. (It is understood + that the user who changes the contents of definitions files in the + Library will not necessarily be able to recompile the application + to use the modified definitions.) + + b) Use a suitable shared library mechanism for linking with the + Library. A suitable mechanism is one that (1) uses at run time a + copy of the library already present on the user's computer system, + rather than copying library functions into the executable, and (2) + will operate properly with a modified version of the library, if + the user installs one, as long as the modified version is + interface-compatible with the version that the work was made with. + + c) Accompany the work with a written offer, valid for at + least three years, to give the same user the materials + specified in Subsection 6a, above, for a charge no more + than the cost of performing this distribution. + + d) If distribution of the work is made by offering access to copy + from a designated place, offer equivalent access to copy the above + specified materials from the same place. + + e) Verify that the user has already received a copy of these + materials or that you have already sent this user a copy. + + For an executable, the required form of the "work that uses the +Library" must include any data and utility programs needed for +reproducing the executable from it. However, as a special exception, +the materials to be distributed need not include anything that is +normally distributed (in either source or binary form) with the major +components (compiler, kernel, and so on) of the operating system on +which the executable runs, unless that component itself accompanies +the executable. + + It may happen that this requirement contradicts the license +restrictions of other proprietary libraries that do not normally +accompany the operating system. Such a contradiction means you cannot +use both them and the Library together in an executable that you +distribute. + + 7. You may place library facilities that are a work based on the +Library side-by-side in a single library together with other library +facilities not covered by this License, and distribute such a combined +library, provided that the separate distribution of the work based on +the Library and of the other library facilities is otherwise +permitted, and provided that you do these two things: + + a) Accompany the combined library with a copy of the same work + based on the Library, uncombined with any other library + facilities. This must be distributed under the terms of the + Sections above. + + b) Give prominent notice with the combined library of the fact + that part of it is a work based on the Library, and explaining + where to find the accompanying uncombined form of the same work. + + 8. You may not copy, modify, sublicense, link with, or distribute +the Library except as expressly provided under this License. Any +attempt otherwise to copy, modify, sublicense, link with, or +distribute the Library is void, and will automatically terminate your +rights under this License. However, parties who have received copies, +or rights, from you under this License will not have their licenses +terminated so long as such parties remain in full compliance. + + 9. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Library or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Library (or any work based on the +Library), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Library or works based on it. + + 10. Each time you redistribute the Library (or any work based on the +Library), the recipient automatically receives a license from the +original licensor to copy, distribute, link with or modify the Library +subject to these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties with +this License. + + 11. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Library at all. For example, if a patent +license would not permit royalty-free redistribution of the Library by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Library. + +If any portion of this section is held invalid or unenforceable under any +particular circumstance, the balance of the section is intended to apply, +and the section as a whole is intended to apply in other circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 12. If the distribution and/or use of the Library is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Library under this License may add +an explicit geographical distribution limitation excluding those countries, +so that distribution is permitted only in or among countries not thus +excluded. In such case, this License incorporates the limitation as if +written in the body of this License. + + 13. The Free Software Foundation may publish revised and/or new +versions of the Lesser General Public License from time to time. +Such new versions will be similar in spirit to the present version, +but may differ in detail to address new problems or concerns. + +Each version is given a distinguishing version number. If the Library +specifies a version number of this License which applies to it and +"any later version", you have the option of following the terms and +conditions either of that version or of any later version published by +the Free Software Foundation. If the Library does not specify a +license version number, you may choose any version ever published by +the Free Software Foundation. + + 14. If you wish to incorporate parts of the Library into other free +programs whose distribution conditions are incompatible with these, +write to the author to ask for permission. For software which is +copyrighted by the Free Software Foundation, write to the Free +Software Foundation; we sometimes make exceptions for this. Our +decision will be guided by the two goals of preserving the free status +of all derivatives of our free software and of promoting the sharing +and reuse of software generally. + + NO WARRANTY + + 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO +WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. +EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR +OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY +KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE +IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE +LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME +THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN +WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY +AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU +FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR +CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE +LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING +RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A +FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF +SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH +DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Libraries + + If you develop a new library, and you want it to be of the greatest +possible use to the public, we recommend making it free software that +everyone can redistribute and change. You can do so by permitting +redistribution under these terms (or, alternatively, under the terms of the +ordinary General Public License). + + To apply these terms, attach the following notices to the library. It is +safest to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least the +"copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public + License as published by the Free Software Foundation; either + version 2.1 of the License, or (at your option) any later version. + + This library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Please note that + this class is for documentary purposes only; plugins may not subclass + IPluginInterface. + +Hello World +=========== + +Here's a basic plugin. It doesn't do much so read on for more ideas or dive +into the :doc:`IPluginInterface ` to see all available hooks. + +.. code-block:: python + + import logging + import os + + from nose.plugins import Plugin + + log = logging.getLogger('nose.plugins.helloworld') + + class HelloWorld(Plugin): + name = 'helloworld' + + def options(self, parser, env=os.environ): + super(HelloWorld, self).options(parser, env=env) + + def configure(self, options, conf): + super(HelloWorld, self).configure(options, conf) + if not self.enabled: + return + + def finalize(self, result): + log.info('Hello pluginized world!') + +Registering +=========== + +.. Note:: + Important note: the following applies only to the default + plugin manager. Other plugin managers may use different means to + locate and load plugins. + +For nose to find a plugin, it must be part of a package that uses +setuptools_, and the plugin must be included in the entry points defined +in the setup.py for the package: + +.. code-block:: python + + setup(name='Some plugin', + # ... + entry_points = { + 'nose.plugins.0.10': [ + 'someplugin = someplugin:SomePlugin' + ] + }, + # ... + ) + +Once the package is installed with install or develop, nose will be able +to load the plugin. + +.. _setuptools: http://peak.telecommunity.com/DevCenter/setuptools + +Registering a plugin without setuptools +======================================= + +It is currently possible to register a plugin programmatically by +creating a custom nose runner like this : + +.. code-block:: python + + import nose + from yourplugin import YourPlugin + + if __name__ == '__main__': + nose.main(addplugins=[YourPlugin()]) + +Defining options +================ + +All plugins must implement the methods ``options(self, parser, env)`` +and ``configure(self, options, conf)``. Subclasses of nose.plugins.Plugin +that want the standard options should call the superclass methods. + +nose uses optparse.OptionParser from the standard library to parse +arguments. A plugin's ``options()`` method receives a parser +instance. It's good form for a plugin to use that instance only to add +additional arguments that take only long arguments (--like-this). Most +of nose's built-in arguments get their default value from an environment +variable. + +A plugin's ``configure()`` method receives the parsed ``OptionParser`` options +object, as well as the current config object. Plugins should configure their +behavior based on the user-selected settings, and may raise exceptions +if the configured behavior is nonsensical. + +Logging +======= + +nose uses the logging classes from the standard library. To enable users +to view debug messages easily, plugins should use ``logging.getLogger()`` to +acquire a logger in the ``nose.plugins`` namespace. + +Recipes +======= + +* Writing a plugin that monitors or controls test result output + + Implement any or all of ``addError``, ``addFailure``, etc., to monitor test + results. If you also want to monitor output, implement + ``setOutputStream`` and keep a reference to the output stream. If you + want to prevent the builtin ``TextTestResult`` output, implement + ``setOutputSteam`` and *return a dummy stream*. The default output will go + to the dummy stream, while you send your desired output to the real stream. + + Example: `examples/html_plugin/htmlplug.py`_ + +* Writing a plugin that handles exceptions + + Subclass :doc:`ErrorClassPlugin `. + + Examples: :doc:`nose.plugins.deprecated `, + :doc:`nose.plugins.skip ` + +* Writing a plugin that adds detail to error reports + + Implement ``formatError`` and/or ``formatFailure``. The error tuple + you return (error class, error message, traceback) will replace the + original error tuple. + + Examples: :doc:`nose.plugins.capture `, + :doc:`nose.plugins.failuredetail ` + +* Writing a plugin that loads tests from files other than python modules + + Implement ``wantFile`` and ``loadTestsFromFile``. In ``wantFile``, + return True for files that you want to examine for tests. In + ``loadTestsFromFile``, for those files, return an iterable + containing TestCases (or yield them as you find them; + ``loadTestsFromFile`` may also be a generator). + + Example: :doc:`nose.plugins.doctests ` + +* Writing a plugin that prints a report + + Implement ``begin`` if you need to perform setup before testing + begins. Implement ``report`` and output your report to the provided stream. + + Examples: :doc:`nose.plugins.cover `, :doc:`nose.plugins.prof ` + +* Writing a plugin that selects or rejects tests + + Implement any or all ``want*`` methods. Return False to reject the test + candidate, True to accept it -- which means that the test candidate + will pass through the rest of the system, so you must be prepared to + load tests from it if tests can't be loaded by the core loader or + another plugin -- and None if you don't care. + + Examples: :doc:`nose.plugins.attrib `, + :doc:`nose.plugins.doctests `, :doc:`nose.plugins.testid ` + + +More Examples +============= + +See any builtin plugin or example plugin in the examples_ directory in +the nose source distribution.

This can speed up CPU-bound test +runs (as long as the number of work processeses is around the number of +processors or cores available), but is mainly useful for IO-bound tests that +spend most of their time waiting for data to arrive from someplace else. + +.. note :: + + See :doc:`../doc_tests/test_multiprocess/multiprocess` for + additional documentation and examples. Use of this plugin on python + 2.5 or earlier requires the multiprocessing_ module, also available + from PyPI. + +.. _multiprocessing : http://code.google.com/p/python-multiprocessing/ + +How tests are distributed +========================= + +The ideal case would be to dispatch each test to a worker process +separately. This ideal is not attainable in all cases, however, because many +test suites depend on context (class, module or package) fixtures. + +The plugin can't know (unless you tell it -- see below!) if a context fixture +can be called many times concurrently (is re-entrant), or if it can be shared +among tests running in different processes. Therefore, if a context has +fixtures, the default behavior is to dispatch the entire suite to a worker as +a unit. + +Controlling distribution +^^^^^^^^^^^^^^^^^^^^^^^^ + +There are two context-level variables that you can use to control this default +behavior. + +If a context's fixtures are re-entrant, set ``_multiprocess_can_split_ = True`` +in the context, and the plugin will dispatch tests in suites bound to that +context as if the context had no fixtures. This means that the fixtures will +execute concurrently and multiple times, typically once per test. + +If a context's fixtures can be shared by tests running in different processes +-- such as a package-level fixture that starts an external http server or +initializes a shared database -- then set ``_multiprocess_shared_ = True`` in +the context. These fixtures will then execute in the primary nose process, and +tests in those contexts will be individually dispatched to run in parallel. + +How results are collected and reported +====================================== + +As each test or suite executes in a worker process, results (failures, errors, +and specially handled exceptions like SkipTest) are collected in that +process. When the worker process finishes, it returns results to the main +nose process. There, any progress output is printed (dots!), and the +results from the test run are combined into a consolidated result +set. When results have been received for all dispatched tests, or all +workers have died, the result summary is output as normal. + +Beware! +======= + +Not all test suites will benefit from, or even operate correctly using, this +plugin. For example, CPU-bound tests will run more slowly if you don't have +multiple processors. There are also some differences in plugin +interactions and behaviors due to the way in which tests are dispatched and +loaded. In general, test loading under this plugin operates as if it were +always in directed mode instead of discovered mode. For instance, doctests +in test modules will always be found when using this plugin with the doctest +plugin. + +But the biggest issue you will face is probably concurrency. Unless you +have kept your tests as religiously pure unit tests, with no side-effects, no +ordering issues, and no external dependencies, chances are you will experience +odd, intermittent and unexplainable failures and errors when using this +plugin. This doesn't necessarily mean the plugin is broken; it may mean that +your test suite is not safe for concurrency. + +New Features in 1.1.0 +===================== + +* functions generated by test generators are now added to the worker queue + making them multi-threaded. +* fixed timeout functionality, now functions will be terminated with a + TimedOutException exception when they exceed their execution time. The + worker processes are not terminated. +* added ``--process-restartworker`` option to restart workers once they are + done, this helps control memory usage.

In addition, all other packages +found in the working directory will be examined for python source files +or directories that match testMatch.

Any python source file, +directory or package that matches the testMatch regular expression +(by default: \fI(?:^|[b_.\-])[Tt]est)\fP will be collected as a test (or +source for collection of tests). In addition, all other packages +found in the working directory will be examined for python source files +or directories that match testMatch. Package discovery descends all +the way down the tree, so package.tests and package.sub.tests and +package.sub.sub2.tests will all be collected. + +Within a test directory or package, any python source file matching +testMatch will be examined for test cases. Within a test module, +functions and classes whose names match testMatch and TestCase +subclasses with any name will be loaded and executed as tests. Tests +may use the assert keyword or raise AssertionErrors to indicate test +failure. TestCase subclasses may do the same or use the various +TestCase methods available. + + +.SS Selecting Tests +To specify which tests to run, pass test names on the command line: + + +.nf +nosetests only_test_this.py +.fi +Test names specified may be file or module names, and may optionally +indicate the test case to run by separating the module or file name +from the test case name with a colon. Filenames may be relative or +absolute. Examples: + + +.nf +nosetests test.module +nosetests another.test:TestCase.test_method +nosetests a.test:TestCase +nosetests /path/to/test/file.py:test_function +.fi +You may also change the working directory where nose looks for tests +by using the \-w switch: + + +.nf +nosetests \-w /path/to/tests +.fi +Note, however, that support for multiple \-w arguments is now deprecated +and will be removed in a future release. As of nose 0.10, you can get +the same behavior by specifying the target directories \fIwithout\fP +the \-w switch: + + +.nf +nosetests /path/to/tests /another/path/to/tests +.fi +Further customization of test selection and loading is possible +through the use of plugins. + +Test result output is identical to that of unittest, except for +the additional features (error classes, and plugin\-supplied +features such as output capture and assert introspection) detailed +in the options below. + + +.SS Configuration +In addition to passing command\-line options, you may also put +configuration options in your project\'s \fIsetup.cfg\fP file, or a .noserc +or nose.cfg file in your home directory. In any of these standard +.ini\-style config files, you put your nosetests configuration in a +\fB[nosetests]\fP section. Options are the same as on the command line, +with the \-\- prefix removed. For options that are simple switches, you +must supply a value: + + +.nf +[nosetests] +verbosity=3 +with\-doctest=1 +.fi +All configuration files that are found will be loaded and their +options combined. You can override the standard config file loading +with the \fB\-c\fP option. + + +.SS Using Plugins +There are numerous nose plugins available via easy_install and +elsewhere. To use a plugin, just install it. The plugin will add +command line options to nosetests. To verify that the plugin is installed, +run: + + +.nf +nosetests \-\-plugins +.fi +You can add \-v or \-vv to that command to show more information +about each plugin. + +If you are running nose.main() or nose.run() from a script, you +can specify a list of plugins to use by passing a list of plugins +with the plugins keyword argument. + + +.SS 0.9 plugins +nose 1.0 can use SOME plugins that were written for nose 0.9. The +default plugin manager inserts a compatibility wrapper around 0.9 +plugins that adapts the changed plugin api calls. However, plugins +that access nose internals are likely to fail, especially if they +attempt to access test case or test suite classes. For example, +plugins that try to determine if a test passed to startTest is an +individual test or a suite will fail, partly because suites are no +longer passed to startTest and partly because it\'s likely that the +plugin is trying to find out if the test is an instance of a class +that no longer exists. + + +.SS 0.10 and 0.11 plugins +All plugins written for nose 0.10 and 0.11 should work with nose 1.0. + + +.SS Options + +.TP +\fB\-V\fR\fR\fR, \fB\-\-version\fR\fR +Output nose version and exit + + +.TP +\fB\-p\fR\fR\fR, \fB\-\-plugins\fR\fR +Output list of available plugins and exit.
