Note: As of 0.7.0 we no longer support 2.6, 3.2, or 3.3. We also removed nose2.compat.

nose2 aims to improve on nose by:

  • providing a better plugin api
  • being easier for users to configure
  • simplifying internal interfaces and processes
  • supporting Python 2 and 3 from the same codebase, without translation
  • encouraging greater community involvement in its development

In service of some of those goals, some features of nose are not
supported in nose2. See differences_ for a thorough rundown.


If you want to make contributions, you can use the Makefile to get started
quickly and easily::

# All you need is a supported version of python and virtualenv installed
make test

tox will run our full test suite
against all supported version of python that you have installed locally.
Don't worry if you don't have all supported versions installed.
Your changes will get tested automatically when you make a PR.

Use make help to see other options.

Original Mission & Present Goals

When nose2 was first written, the plan for its future was to wait for
unittest2 plugins to be released (nose2 is actually based on the
plugins branch of unittest2).
Once that was done, nose2 was to become a set of plugins and default
configuration for unittest2.

However, based on the current status of unittest2, it is doubtful that this
plan will ever be carried out.
