nose: builtin plugin: testid
This plugin adds a test id (like #1) to each test name output. 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 #2 tests.test_c ... ok
Then you can rerun individual tests by supplying just the id numbers:
% nosetests -v --with-id 2 #2 tests.test_b ... ok
Then you can rerun individual tests by supplying just the 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.
