### **[pynose](https://github.com/mdmintz/pynose)** fixes **[nose](https://nose.readthedocs.io/en/latest/)** to extend [unittest](https://docs.python.org/3/library/unittest.html) and make testing easier.



--------



``pynose`` is an updated version of ``nose``, originally made by Jason Pellerin.



This version of ``nose`` is compatible with ``Python 3.7+`` (including ``3.13+``).



Changes in ``pynose`` from legacy ``nose`` include:

* Fixes "AttributeError: module 'collections' has no attribute 'Callable'."

* Fixes "AttributeError: module 'inspect' has no attribute 'getargspec'."

* Fixes "ImportError: cannot import name '_TextTestResult' from 'unittest'."

* Fixes "RuntimeWarning: TestResult has no addDuration method."

* Fixes "DeprecationWarning: pkg_resources is deprecated as an API."

* Fixes all ``flake8`` issues from the original ``nose``.

* Replaces the ``imp`` module with the newer ``importlib`` module.

* The default logging level now hides `"INFO"` logs for less noise.

* Adds ``--capture-logs`` for hiding output from all logging levels.

* Adds ``--logging-init`` to use ``logging.basicConfig(level)``.

* The ``-s`` option is always active to see the output of ``print()``.

* Adds ``--capture-output`` for hiding the output of ``print()``.

* Adds ``--co`` as a shortcut to using ``--collect-only``.



--------



The original description of ``nose``:



>nose extends the test loading and running features of unittest, making

it easier to write, find and run tests.



>By default, nose runs tests in files or directories under the current

working directory whose names include "test" or "Test" at a word

boundary (like "test_this" or "functional_test" or "TestClass" but not

"libtest"). Test output is similar to that of unittest, but also includes

captured stdout output from failing tests, for easy print-style debugging.



>These features, and many more, are customizable through the use of

plugins. Plugins included with nose provide support for doctest, code

coverage and profiling, flexible attribute-based test selection,

output capture and more. More information about writing plugins

may be found on in the nose API documentation, here:

https://nose.readthedocs.io/en/latest/

```



Basic usage

***********



Use "pynose" OR "nosetests" to run tests:



    pynose [options] [(optional) test files or directories]



    nosetests [options] [(optional) test files or directories]



In addition to passing command-line options, you may also put

configuration options in a .noserc or nose.cfg file in your home

directory. 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 is also possibility to disable configuration files loading (might

be useful when running i.e. tox and you do not want your global nose

config file to be used by tox). In order to ignore those configuration

files simply set an environment variable "NOSE_IGNORE_CONFIG_FILES".



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 do not 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.



**It is important to note that the default behavior of nose is to not

include tests from files which are executable.**  To include tests

from such files, remove their executable bit or use the --exe flag

(see 'Options' section below).



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 *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.



Options

-------



-V, --version



   Output nose version and exit



-p, --plugins



   Output list of available plugins and exit. Combine with higher

   verbosity for greater detail



-v=DEFAULT, --verbose=DEFAULT



   Be more verbose. [NOSE_VERBOSE]



--verbosity=VERBOSITY



   Set verbosity; --verbosity=2 is the same as -v



-q=DEFAULT, --quiet=DEFAULT



   Be less verbose



-c=FILES, --config=FILES



   Load configuration from config file(s). May be specified multiple

   times; in that case, all config files will be loaded and combined



-w=WHERE, --where=WHERE



   Look for tests in this directory. May be specified multiple times.

   The first directory passed will be used as the working directory,

   in place of the current working directory, which is the default.

   Others will be added to the list of tests to execute. [NOSE_WHERE]



--py3where=PY3WHERE



   Look for tests in this directory under Python 3.x. Functions the

   same as 'where', but only applies if running under Python 3.x or

   above.  Note that, if present under 3.x, this option completely

   replaces any directories specified with 'where', so the 'where'

   option becomes ineffective. [NOSE_PY3WHERE]



-m=REGEX, --match=REGEX, --testmatch=REGEX



   Files, directories, function names, and class names that match this

   regular expression are considered tests.  Default:

   (?:^|[b_./-])[Tt]est [NOSE_TESTMATCH]



--tests=NAMES



   Run these tests (comma-separated list). This argument is useful

   mainly from configuration files; on the command line, just pass the

   tests to run as additional arguments with no switch.



-l=DEFAULT, --debug=DEFAULT



   Activate debug logging for one or more systems. Available debug

   loggers: nose, nose.importer, nose.inspector, nose.plugins,

   nose.result and nose.selector. Separate multiple names with a

   comma.



--debug-log=FILE



   Log debug messages to this file (default: sys.stderr)



--logging-config=FILE, --log-config=FILE



   Load logging config from this file -- bypasses all other logging

   config settings.



-I=REGEX, --ignore-files=REGEX



   Completely ignore any file that matches this regular expression.

   Takes precedence over any other settings or plugins. Specifying

   this option will replace the default setting. Specify this option

   multiple times to add more regular expressions [NOSE_IGNORE_FILES]



-e=REGEX, --exclude=REGEX



   Do not run tests that match regular expression [NOSE_EXCLUDE]



-i=REGEX, --include=REGEX



   This regular expression will be applied to files, directories,

   function names, and class names for a chance to include additional

   tests that do not match TESTMATCH.  Specify this option multiple

   times to add more regular expressions [NOSE_INCLUDE]



-x, --stop



   Stop running tests after the first error or failure



-P, --no-path-adjustment



   Do not make any changes to sys.path when loading tests [NOSE_NOPATH]



--exe



   Look for tests in python modules that are executable. Normal

   behavior is to exclude executable modules, since they may not be

   import-safe [NOSE_INCLUDE_EXE]



--noexe



   DO NOT look for tests in python modules that are executable. (The

   default on the windows platform is to do so.)



--traverse-namespace



   Traverse through all path entries of a namespace package



--first-package-wins, --first-pkg-wins, --1st-pkg-wins



   The nose importer will normally evict a package from sys.modules if

   it sees a package with the same name in a different location. Set

   this option to disable that behavior.



--no-byte-compile



   Prevent nose from byte-compiling the source into .pyc files while

   nose is scanning for and running tests.



-a=ATTR, --attr=ATTR



   Run only tests that have attributes specified by ATTR [NOSE_ATTR]



-A=EXPR, --eval-attr=EXPR



   Run only tests for whose attributes the Python expression EXPR

   evaluates to True [NOSE_EVAL_ATTR]



-s, --nocapture



   Do not capture stdout (any stdout output will be printed

   immediately) [NOSE_NOCAPTURE]



--nologcapture



   Disable logging capture plugin. Logging configuration will be left

   intact. [NOSE_NOLOGCAPTURE]



--logging-format=FORMAT



   Specify custom format to print statements. Uses the same format as

   used by standard logging handlers. [NOSE_LOGFORMAT]



--logging-datefmt=FORMAT



   Specify custom date/time format to print statements. Uses the same

   format as used by standard logging handlers. [NOSE_LOGDATEFMT]



--logging-filter=FILTER



   Specify which statements to filter in/out. By default, everything

   is captured. If the output is too verbose, use this option to

   filter out needless output. Example: filter=foo will capture

   statements issued ONLY to  foo or foo.what.ever.sub but not foobar

   or other logger. Specify multiple loggers with comma:

   filter=foo,bar,baz. If any logger name is prefixed with a minus, eg

   filter=-foo, it will be excluded rather than included. Default:

   exclude logging messages from nose itself (-nose). [NOSE_LOGFILTER]



--logging-clear-handlers



   Clear all other logging handlers



--logging-level=LEVEL



   Set the log level to capture. (Default: "WARNING")

   Levels: ["DEBUG", "INFO", "WARNING", "ERROR", "CRITICAL"]

   You may need to include `--logging-init` to change the default.



--with-coverage



   Enable plugin Coverage: Activate a coverage report using the

   Ned Batchelder coverage module. [NOSE_WITH_COVERAGE]



--cover-package=PACKAGE



   Restrict coverage output to selected packages [NOSE_COVER_PACKAGE]



--cover-erase



   Erase previously collected coverage statistics before run



--cover-tests



   Include test modules in coverage report [NOSE_COVER_TESTS]



--cover-min-percentage=DEFAULT



   Minimum percentage of coverage for tests to pass

   [NOSE_COVER_MIN_PERCENTAGE]



--cover-inclusive



   Include all python files under working directory in coverage

   report.  Useful for discovering holes in test coverage if not all

   files are imported by the test suite. [NOSE_COVER_INCLUSIVE]



--cover-html



   Produce HTML coverage information



--cover-html-dir=DIR



   Produce HTML coverage information in dir



--cover-branches



   Include branch coverage in coverage report [NOSE_COVER_BRANCHES]



--cover-xml



   Produce XML coverage information



--cover-xml-file=FILE



   Produce XML coverage information in file



--pdb



   Drop into debugger on failures or errors



--pdb-failures



   Drop into debugger on failures



--pdb-errors



   Drop into debugger on errors



--no-deprecated



   Disable special handling of DeprecatedTest exceptions.



--with-doctest



   Enable plugin Doctest: Activate doctest plugin to find and run

   doctests in non-test modules. [NOSE_WITH_DOCTEST]



--doctest-tests



   Also look for doctests in test modules. Note that classes, methods

   and functions should have either doctests or non-doctest tests, not

   both. [NOSE_DOCTEST_TESTS]



--doctest-extension=EXT



   Also look for doctests in files with this extension

   [NOSE_DOCTEST_EXTENSION]



--doctest-result-variable=VAR



   Change the variable name set to the result of the last interpreter

   command from the default '_'. Can be used to avoid conflicts with

   the _() function used for text translation.

   [NOSE_DOCTEST_RESULT_VAR]



--doctest-fixtures=SUFFIX



   Find fixtures for a doctest file in module with this name appended

   to the base name of the doctest file



--doctest-options=OPTIONS



   Specify options to pass to doctest. Eg.

   '+ELLIPSIS,+NORMALIZE_WHITESPACE'



--with-isolation



   Enable plugin IsolationPlugin: Activate the isolation plugin to

   isolate changes to external modules to a single test module or

   package. The isolation plugin resets the contents of sys.modules

   after each test module or package runs to its state before the

   test. PLEASE NOTE that this plugin should not be used with the

   coverage plugin, or in any other case where module reloading may

   produce undesirable side-effects. [NOSE_WITH_ISOLATION]



-d, --detailed-errors, --failure-detail



   Add detail to error output by attempting to evaluate failed asserts

   [NOSE_DETAILED_ERRORS]



--no-skip



   Disable special handling of SkipTest exceptions.



--with-id



   Enable plugin TestId: Activate to add a test id (like #1) to each

   test name output. Activate with --failed to rerun failing tests

   only. [NOSE_WITH_ID]



--id-file=FILE



   Store test ids found in test runs in this file. Default is the file

   .noseids in the working directory.



--failed



   Run the tests that failed in the last test run.



--processes=NUM



   Spread test run among this many processes. Set a number equal to

   the number of processors or cores in your machine for best results.

   Pass a negative number to have the number of processes

   automatically set to the number of cores. Passing 0 means to

   disable parallel testing. Default is 0 unless NOSE_PROCESSES is

   set. [NOSE_PROCESSES]



--process-timeout=SECONDS



   Set timeout for return of results from each test runner process.

   Default is 10. [NOSE_PROCESS_TIMEOUT]



--process-restartworker



   If set, will restart each worker process once their tests are done,

   this helps control memory leaks from killing the system.

   [NOSE_PROCESS_RESTARTWORKER]



--with-xunit



   Enable plugin Xunit: This plugin provides test results in the

   standard XUnit XML format. [NOSE_WITH_XUNIT]



--xunit-file=FILE



   Path to xml file to store the xunit report in. Default is

   nosetests.xml in the working directory [NOSE_XUNIT_FILE]



--xunit-testsuite-name=PACKAGE



   Name of the testsuite in the xunit xml, generated by plugin.

   Default test suite name is nosetests.



--all-modules



   Enable plugin AllModules: Collect tests from all python modules.

   [NOSE_ALL_MODULES]



--co, --collect-only



   Enable collect-only: Collect and output test names only,

   but do not run any tests. [COLLECT_ONLY]



--capture-output, --capture_output



   Enable capturing output. This hides the output of print().

   (os.environ["NOSE_CAPTURE"] = "1")



--capture-logs, --capture_logs



   Enable capturing logs. This hides output from all log levels.

   (os.environ["NOSE_CAPTURELOGS"] = "1")



--logging-init



   Using this will call `logging.basicConfig(level)`, which may

   be needed if you're trying to change the default logging level

   with `--logging-level=LEVEL`.
