Nose

It enhances test loading and test running features of Python source code.

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.

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.

What is new in this release:

• Fixed:
• nose.importer causes bizarre import errors if sys.path includes symlinks.
• Suppress tracebacks caused by configuration errors.
• Doctest failures under Python 3.
• test_address's checking for builtins to work with Python 2 and 3.
• A bug where nose.tools was not being installed on systems without setuptools.
• A bug in xunit that was causing it to die ungracefully under Python 3.
• logcapture shouldn't buffer records, breaks %r point-in-time formatting.
• Added:
• Support for Python 3.3.
• The ability to skip generating .pyc files with --no-byte-complie.
