"""nose-compatibility plugin: allow to run nose test suites natively.
This is an experimental plugin for allowing to run tests written
in 'nosetests style with py.test.
Usage
-------------
type::
py.test # instead of 'nosetests'
and you should be able to run nose style tests and at the same
time can make full use of py.test's capabilities.
Supported nose Idioms
----------------------
* setup and teardown at module/class/method level
* SkipTest exceptions and markers
* setup/teardown decorators
* yield-based tests and their setup
* general usage of nose utilities
Unsupported idioms / issues
----------------------------------
- nose-style doctests are not collected and executed correctly,
also fixtures don't work.
- no nose-configuration is recognized
If you find other issues or have suggestions please run::
py.test --pastebin=all
and send the resulting URL to a py.test contact channel,
at best to the mailing list.
