After -you've run once to generate test ids, you can re-run individual -tests by activating the plugin and passing the ids (with or -without the # prefix) instead of test names. - -For example, if your normal test run looks like:: - - % nosetests -v - tests.test_a ... ok - tests.test_b ... ok - tests.test_c ... ok - -When adding ``--with-id`` you'll see:: - - % nosetests -v --with-id - #1 tests.test_a ... ok - #2 tests.test_b ... ok - #3 tests.test_c ... ok - -Then you can re-run individual tests by supplying just an id number:: - - % nosetests -v --with-id 2 - #2 tests.test_b ... ok - -You can also pass multiple id numbers:: - - % nosetests -v --with-id 2 3 - #2 tests.test_b ... ok - #3 tests.test_c ... ok - -Since most shells consider '#' a special character, you can leave it out when -specifying a test id. - -Note that when run without the -v switch, no special output is displayed, but -the ids file is still written. - -Looping over failed tests -------------------------- - -This plugin also adds a mode that will direct the test runner to record -failed tests. Subsequent test runs will then run only the tests that failed -last time. Activate this mode with the ``--failed`` switch:: - - % nosetests -v --failed - #1 test.test_a ... ok - #2 test.test_b ... ERROR - #3 test.test_c ... FAILED - #4 test.test_d ... ok - -On the second run, only tests #2 and #3 will run:: - - % nosetests -v --failed - #2 test.test_b ... ERROR - #3 test.test_c ... FAILED - -As you correct errors and tests pass, they'll drop out of subsequent runs. - -First:: - - % nosetests -v --failed - #2 test.test_b ... ok - #3 test.test_c ... FAILED - -Second:: - - % nosetests -v --failed - #3 test.test_c ... FAILED - -When all tests pass, the full set will run on the next invocation. - -First:: - - % nosetests -v --failed - #3 test.test_c ... ok - -Second:: - - % nosetests -v --failed - #1 test.test_a ... ok - #2 test.test_b ... ok - #3 test.test_c ... ok - #4 test.test_d ... ok - -.. note :: - - If you expect to use ``--failed`` regularly, it's a good idea to always run - using the ``--with-id`` option. This will ensure that an id file is always - created, allowing you to add ``--failed`` to the command line as soon as - you have failing tests. Otherwise, your first run using ``--failed`` will - (perhaps surprisingly) run *all* tests, because there won't be an id file - containing the record of failed tests from your previous run. - -""" -__test__ = False - -import logging -import os -from nose.plugins import Plugin -from nose.util import src, set - -try: - from cPickle import dump, load -except ImportError: - from pickle import dump, load - -log = logging.getLogger(__name__) - - -class TestId(Plugin): - """ - Activate to add a test id (like #1) to each test name output.
