Finding tests in all modules ============================ Normally, nose only looks for tests in modules whose names match testMatch. By default that means modules with 'test' or 'Test' at the start of the name after an underscore (_) or dash (-) or other non-alphanumeric character. If you want to collect tests from all modules, use the ``--all-modules`` command line argument to activate the :doc:`allmodules plugin <../../plugins/allmodules>`. .. Note :: The function :func:`nose.plugins.plugintest.run` reformats test result output to remove timings, which will vary from run to run, and redirects the output to stdout. >>> from nose.plugins.plugintest import run_buffered as run .. >>> import os >>> support = os.path.join(os.path.dirname(__file__), 'support') >>> argv = [__file__, '-v', support] The target directory contains a test module and a normal module. >>> support_files = [d for d in os.listdir(support) ... if not d.startswith('.') ... and d.endswith('.py')] >>> support_files.sort() >>> support_files ['mod.py', 'test.py'] When run without ``--all-modules``, only the test module is examined for tests. >>> run(argv=argv) test.test ... ok ---------------------------------------------------------------------- Ran 1 test in ...s OK When ``--all-modules`` is active, both modules are examined. >>> from nose.plugins.allmodules import AllModules >>> argv = [__file__, '-v', '--all-modules', support] >>> run(argv=argv, plugins=[AllModules()]) # doctest: +REPORT_NDIFF mod.test ... ok mod.test_fails ... FAIL test.test ... ok ====================================================================== FAIL: mod.test_fails ---------------------------------------------------------------------- Traceback (most recent call last): ...
