Basic usage *********** Use the nosetests script (after installation by setuptools): 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 possiblity to disable configuration files loading (might be useful when runnig i.e. tox and you don't 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 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. **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'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. 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 Don't 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 Don't 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 nose's 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 Don't 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=DEFAULT Set the log level to capture --with-coverage Enable plugin Coverage: Activate a coverage report using Ned Batchelder's 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] --with-profile Enable plugin Profile: Use this plugin to run tests using the hotshot profiler. [NOSE_WITH_PROFILE] --profile-sort=SORT Set sort order for profiler output --profile-stats-file=FILE Profiler stats file; default is a new temp file on each run --profile-restrict=RESTRICT Restrict profiler output. See help for pstats.Stats for details --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] --collect-only Enable collect-only: Collect and output test names only, don't run any tests. [COLLECT_ONLY]
