"""Collection of fixtures for simplified work with blockers.

You can use the :py:func:`blocker` fixture to retrieve any blocker
using blocker syntax (as described in :py:mod:`cfme.metaplugins.blockers`).
The :py:func:`bug` fixture is specific for bugzilla,
it accepts number argument and spits out the BUGZILLA BUG!
(a :py:class:``, not a :py:class:`utils.blockers.BZ`!).
The :py:func:`blockers` retrieves list of all blockers
as specified in the meta marker.
All of them are converted to the :py:class:`utils.blockers.Blocker` instances
