[TIP] pytest-2.1.2: bug fixes and fixes for jython

[holger krekel]

pytest-2.1.2 is a minor backward compatible maintenance release of the
popular py.test testing tool.  pytest is commonly used for unit,
functional- and integration testing.  See extensive docs with examples
here:

     http://pytest.org/

Most bug fixes address remaining issues with the perfected assertions
introduced in the 2.1 series - many thanks to the bug reporters and to Benjamin
Peterson for helping to fix them.  pytest should also work better with
Jython-2.5.1 (and Jython trunk, but not Jython-2.5.2).

If you want to install or upgrade pytest, just type one of::

    pip install -U pytest # or
    easy_install -U pytest

best,
