nose extends unittest to make testing easier
it easier to write, find and run tests.
By default, nose will run 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: http://readthedocs.org/docs/nose/
