pynose 🐍👃 PyPI version

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``pynose`` is an updated version of ``nose``, originally made by Jason Pellerin.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