I'm pleased to announce the 0.9.0a1 release of nose, a test runner that
brings py.test convenience to unittest, without resorting to (too much)
magic.

nose 0.9 includes a host of new features, as well as numerous
backwards-incompatible changes to interfaces and implementation. For
this reason, I'm releasing it first as an alpha version.

Thanks to the many folks who have contributed patches and ideas and
made bug reports for the development version of 0.9, especially Mika
Eloranta, Jay Parlar, Kevin Dangoor, Scot Doyle and Philip J. Eby.

Here's a quick rundown of what's new in 0.9.0a1.

- Plugins

 The most important new feature is support for plugins using
setuptools entrypoints. nose plugins can select and load tests (like
the builtin doctest plugin), reject tests (like the builtin attrib
plugin, contributed by Mika Eloranta, that allows users to select tests
by attribute), watch and report on tests (like the builtin coverage and
profiler plugins), completely replace test result output (like the html
result plugin in the examples directory) or any combination of the
above. Writing plugins is simple: subclass nose.plugins.Plugin and
implement any of the methods in nose.plugins.IPluginInterface.

- Better compatibility with unittest

 Test loading has been consolidated into a test loader class that is
drop-in compatible with unittest.TestLoader. Likewise test result
output, including output capture, assert introspection, and support for
skipped and deprecated tests, in nose.result.TextTestResult. If you
want those features and not the rest of nose, you can use just those
classes. nose.main() has also been rewritten to have the same signature
as unittest.main().

- Better command line interface

 Command line test selection is more intuitive and powerful, enabling
easy and correct running of single tests while ensuring that fixtures
(setup and teardown) are correctly executed at all levels. No more -f
-m or -o options; now simply specify the tests to run:

   nosetests this/file.py that.module

 Tests may be specified down to the callable:

   nosetests this/file.py:TestClass that.module:this_test
   nosetests that.module:TestClass.test_method

 There are also new options for dropping into pdb on errors or
failures, and stopping the test run on the first error or failure
(thanks to Kevin Dangoor for the idea).

- More!

 Helpful test decorators and functions in nose.tools. Support for
generators in test classes. Better import path handling -- that you can
shut off! Detailed verbose logging using the logging package. And
more...
